Identifiction of the Area 1. Name English: Quadrilátero Ferrífero Geopark Portuguese: Geopark Quadrilátero Ferrífero
2. Surface area, physical and human geography characteristics 2.1. Physiographic aspects As described by Barbosa & Rodrigues (1967), the Quadrilátero Ferrífero - QF – corresponds to a geological block from the Precambrian epoch whose contours were revealed by differential erosion. Thus,quartzites and itabirites form crests in altitudes between 1,300 and 1,600 meters. These crests correspond to the alignment of the Curral Range to the North, of the Ouro Branco Range to the South, of the Moeda Range to the West, and of the block formed by the Caraça Range, and the beginning of the Espinhaço Range (Serra do Espinhaço) to the North. This structure is already observed in the map elaborated by Claussen in 1840 (Map 5). The influence of altitude variations favors the appearance of microclimates presenting temperature and humidity quite different from the annual mean temperature of the region, which is approximately 20°C, and annual mean precipitation ranging from 1,300mm to 2,100mm. The predominantly hot-tempered climate of the Quadrilátero Ferrífero is marked by two well-defined seasons: dry winter and wet summer (Silva, 2007). The headwaters of two large hydrographic basins – São Francisco River Basin (Bacia do Rio São Francisco), and Doce River Basin (Bacia do Rio Doce) - are located in the region and supply water to the Metropolitan Area of Belo Horizonte. Geologic structures influence the course of rivers, forming stretches of cascades, and deep valleys. This occurs mainly in the Velhas River (Rio das Velhas), where the variations in the altitude of the relief are remarkable. (Barbosa & Rodrigues, 1967).

2.2. Biological aspects, bioma The Quadrilátero Ferrífero spreads across a region of vegetal covering which shares the biomes the Brazilian Tropical Savanna (Cerrado) and the Atlantic Rainforest (Mata Atlântica). The wide diversity of hydrological, pedological, topographical, geological, and geomorphological features, as previously observed, creates sufficient conditions for the existence of a great floristic diversity in the region, with a variety of biota, especially seasonal forests, semi-deciduous forests, montane, and submon-
Miguel Andrade
tane. Although it was formerly well-distributed, it should be observed that the Atlantic Rainforest biome is nowadays extremely degraded, restricted to isoladed fragments of vegetation. The Brazilian Tropical
Savanna biome is constituted by a mosaic of
phytophysiognomies, where forest areas as ciliary forests, gallery forests, open areas including campo limpo (field with sparse vegetation), campo sujo (dirty field), campo cerrado (cerrado field) as well as intermediate areas as cerradão (cerrado woodlands) and cerrado sensu stricto are observed. A typical physiognomy of the Brazilian Tropical Savanna - the campo rupestre(fields of altitude in iron ore ranges) – is characteristic in the Quadrilátero Ferrífero. It usually occurs at altitudes over 900 meters, on rocky outcrops, presenting sandy, fine or pebbly soil, poor in
nutrients and organic matter, and low capacity
to retain water.
2.3. Human aspects The population of the area proposed for the Geopark is of approximately 3,154,506 inhabitants, and since the discovery of gold at the end of the 17th century to present the region of the Quadrilátero Ferrífero has the largest urban concentration of the state of Minas Gerais. In its northern part, the state capital of Belo Horizonte has nearly 2.4 million inhabitants. The cities of the region have a population of about 22% of the state population, and they are responsible for 26.8% of the GDP for the state of Minas Gerais.

3.1. History of the proposition of the Geopark As the potential of the Quadrilátero Ferrífero for the comprehension of the Earth Sciences and the mining history is widely accepted, evaluation studies on the potential of this region to become a Geopark from UNESCO which was initially proposed by the Geopark Project of the Brazilian Geologocal Survey – CPRM (Schobbenhaus 2006) have been performed since 2006. One of the pioneer studies was the PhD thesis entitled “Geological heritage and geoconservation in the Quadrilátero Ferrífero: potential to create a Geopark from UNESCO” (Ruchkys 2007), submitted at the UFMG. In this very year, the Mineral and Metallurgic Pole of Excellence from State Secretary of Science, Technology and Higher Education of Minas Gerais – SECTES, issued the Public Notice Number 14-2007 Network of Mineral Technologies by which the Research Support Foundation of Minas Gerais – FAPEMIG approved a project aiming selection and establishment of pilot sites to create the Quadrilátero Ferrífero Geopark. The project was launched with the „Seminar Quadrilátero Ferrífero Geopark: a new perspective of use for the geoscientific heritage‟ which included lectures held by UNESCO representatives, by the Brazilian Geological Survey (Serviço Geológico do Brasil – CPRM), by universities, by mining companies, by NGOs, and by the Araripe Geopark in Brazil. After this seminar, many communications were presented at renowned events for the diffuse proposal, as well as workshops for the communities surrounding some geological sites. In April 2009, the Promoting Group of Quadrilátero Ferrífero Geopark was created by the State Government, which, under the supervision of SECTES/Mineral and Metallurgic Pole of Excellence, promoted the necessary political articulations for the effective proposal of the Geopark to the State Government.
3.2. Management Proposal The territorial management systems have become considerably more complex in Brazil. The model recommended by UNESCO for the creation of geoparks is innovative and the State of Minas Gerais pioneered in proposing the compatibility of conservation and scientific education with the economical activity, signalizing a commitment of the State Government as a promoter of the economical, social, and environmental development. 3

The Quadrilátero Institute, which will be in charge of the geopark management, is being created. This institute is a non-profit private entity and will hold as an objective “to develop and to promote actions related to the integrated territorial development of the Quadrilátero Ferrífero presenting sustainable social, economical, cultural, and environmental bases”. The system of management of the Quadrilátero Ferrífero Geopark is comprised of Management Committee, Instituto Quadrilátero and sites that are managed independently: 1. Management Committee - With headquarters in the Fundação Centro Tecnológico de Minas Gerais - CETEC, the Committee evolves of the Quadrilátero Ferrífero Geopark Promoting Group, who are initially responsible for supporting and proposing the implementation of the Quadrilátero Ferrífero Geopark. The Management Committee establishes and monitors the guidelines of the installation and functioning of Geopark. The guidelines are executed for the Geopark QF Operações entailed to the Instituto Quadrilátero. The powers of the Committee Manager are to elaborate Start-up Guidelines for the Geopark, to control the performance of the Guidelines, to support the 4
Management of the Geopark via its Technical Chambers (Scientist, Tourism, Socio-environmental, Culture and Education), to establishing the rules for communication of the Geopark with the society This Committee will be consolidated in the following two months evolving from the current Promoting Group. 2.
The Instituto Quadrilátero - A private organisation without lucrative ends, that in 2006 received of Government of the State of Minas Gerais the qualification of Organisation of the Civil Society of Public Interest (OSCIP), which qualifies it to act as a partner also in governmental projects.
The Instituto is responsible for management of the Geopark and has the objective to develop and to promote actions connected to the comprehensive territorial development of the Quadrilátero Ferrífero with social, economic, cultural and sustainable environmental bases. The Instituto Quadrilátero, via Division Geopark QF Operações, validates the cooperation agreements with the institutions managing of the sites, supports all activities related to the implementation and operation of the Geopark, including capturing resources in Brazil and abroad. The tasks of Geopark QF Operações are: a. Drawing up the procedures that to do work the guidelines of the Management Committee for the operation of Geopark; b. Articulate the cooperation agreements to be signed with the institutions managing of sites; c. Attract resources and partners; d. Elaborate reports on the operation of Geopark for the Management Committee; e. Administrate the programs of training of managers of sites; f. Coordinate the development continues of new content and new exhibitions; g. Establish procedures to finance sites and monitors them; h. Define the design of products associated with the Geopark; and i.
Mobilise the communities and visitors on specific campaigns, among other functions.

3.3. Mechanisms for establishing the geopark The mechanisms for establishing the geopark and the regulation of human activities in the sites proposed are conditioned to the Brazilian legislation. The majority of the geological sites proposed coincides with previously created conservation units recognized by the federal and state entities where the environmental agencies belonging to the system SEMAD: IGAM, FEAM, and IEF, along with COPAM, participate in the processes of environmental control, monitoring, and regulations. As it concerns an area of great mineral importance, the DNPM plays a strong role in the control and release of areas for mining, according to legal conditions. The mining sector is experiencing a new moment of environmental responsibility and has pointed to the environmental compensations performing convenient actions towards the implementation of centers and programs of environmental education, and interpretation which may be developed in the sites proposed for the geopark. 6
Regarding the Quadrilátero Ferrífero, the performance of outstanding entrepreneurs as Vale (main Brazilian mining company), Açominas (iron and steel metallurgy), and AngloGold (gold mining) among others, is remarkable. The federal legislation that regulates the use of natural resources - Forest Code Law 4,771/65 and Law 5,197/67 of Fauna Protection, and CONAMA resolution 13/90, relating to the 10km buffer zone around the Conservation Units - UCs, set bounds to the use of resources, determine the creation of UCs at a government level, demarcate legal preservation areas within private properties, as well as economical activities permitted around the Conservation Units (SEMAD, 2005). Law 6,902 of April 27, 1981 institutes the Environmental Protected Areas - APAs, provide legal mechanisms for the management of soil and human activities in private areas, entrusting the environmental agency with the duty of managing the licensing of these activities. It should be emphasized that the area proposed for the Geopark is part of the Southern Environmental Protected Area of the Belo Horizonte Metropolitan Region - APA Sul RMBH. Special Premise The installation of the Quadrilátero Ferrífero Geopark sites in areas under mineral exploration rights will be allways progressed after the owners approval and the proposed strategy by the Promoting Group is to invite these private owners to led the site installation, management, and sponsoring.

1.1 – Area proposed for the Geopark The area proposed for the Geopark covers: Curral Range (Serra do Curral) to the North from the Rola Moça Range (Serra do Rola Moça) to the Piedade Range (Serra da Piedade), Moeda Range (Serra da Moeda) to the West; Ouro Branco Range (Serra de Ouro Branco), Itatiaia Range (Serra do Itatiaia), Itacolomi Peak (Pico do Itacolomi) to the south; Passagem / Matacavalos /Mariana, Antônio Pereira, Frazão Peak (Pico do Frazão), Caraça Range (Serra do Caraça), Tamanduá Range (Serra do Tamanduá), Brucutú Peak (Pico do Brucutú), Cambotas Range (Serra das Cambotas), Piedade mountain range to the east, comprising an approximate area of 5,900 km², involving several municipalities whose economy is based on mineral extraction and metallurgy. This region benefits from a privileged location, for it is partly situated in the metropolitan area of Belo Horizonte (capital of the state of Minas Gerais), providing therefore good access options. It includes the municipalities of São Gonçalo do Rio Abaixo, Barão de Cocais, Santa Bárbara, Catas Altas, Alvinópolis, Mariana, Ouro Preto, Ouro Branco, Congonhas, Belo Vale, Moeda, Itabirito, Rio Acima, Brumadinho, Mario Campos, Sarzedo, Ibirité, Nova Lima, Raposos, Sabará, Caeté, Belo Horizonte, Santa Luzia in the state of Minas Gerais.

General geological description
2.1 – Evolution of the geoscientific knowledge The geoscientific interest in the Quadrilátero Ferrífero is well expressed by the quantity of works developed in the region, which were initiated through the research work developed by Vieira Couto and afterwards by Wilhelm Ludwig vonEschwege, who published several works on the mineral wealth of Minas Gerais in Europe from 1811 to1833. Besides Eschwege, the Bavarian naturalists Spix and Martius as well as the travellers Mawe, Burton and Saint-Hilaire published interesting observations about the Quadrilátero Ferrífero. In 1876, the School of Mines of Ouro Preto, which enabled the multiplication of studies and
publications on the
Piedade Range
Quadrilátero Ferrífero including papers published in other languages and disseminated in foreign countries, was inaugurated. The French mineralogist Henry Gorceix was appointed director of the School of Mines, which soon became an internationally highly regarded school. The detailed geological
knowledge of the Quadrilátero Ferrífero, regarding its
geological
cartography, was compiled by the Program of Geological
Mapping conducted by the USGS and DNPM from 1945 to 1962. As a result of these works, maps containing more than 40 sheets at a scale of 1:25,000 were presented in a series of publications, summarized by Dorr at a scale of 1:150,000 in 1969. In the final summary, the author presents a stratigraphic column for the Quadrilátero Ferrífero, which with some is still in use (Dorr, 1969).

2.2 – Geological context The geological context of the Quadrilátero Ferrífero is characterized by three large sets of rocks: metamorphic complexes of Archean crystalline rocks; sequences of Archean greenstone belts represented by the Rio das Velhas Supergroup and Paleo and Mesoproterozoic metasedimentary sequences represented by the Minas Supergroup, Sabará Group, Itacolomi Group, and Espinhaço Supergroup (Map 2).
Map2
The metamorphic complexes of Archean crystalline rocks are formed by a different lithologies diversity exposed in the adjacencies and in the central portion of the Quadrilátero Ferrífero. They are structured in domes and constitute of polydeformed gneisses with tonalite to granite composition and subordinately, granites, granodiorites, amphibolites, and ultramafic rocks, generated in the Archean and remobilized during Proterozoic events (Herz 1970, Cordani et al. 1980, Machado et al. 1989, Belo de Oliveira & Teixeira 1990, Romano et al. 1992, Machado & Carneiro 1992, Noce 1995). 11
Application Dossier Geopark Quadrilatero Ferrifero Project The Rio das Velhas Supergroup is considered by Almeida (1977) and Schorscher (1986) a greenstone belt sequence. According to Dorr (1969), the rocks that form this unit are composed by the Nova Lima and Maquiné groups. Since then, several proposals of lithostratigraphic denomination and division have been presented for this supergroup. Despite the divergences regarding the subdivisions, there is consensus that the Rio das Velhas Supergroup is composed by the two original groups defined by Dorr (1969): Nova Lima and Maquiné. The Nova Lima Group is the basal unit of the Rio das Velhas Supergroup and is constituted by phyllites, graphite phyllites, chlorite-schists, sericite-schists, metagraywackes, mafic, and ultramafic rocks, iron formations of the Algoma type, metacherts, and dolomites. Some informal lithostratigraphic units are proposed by Ladeira (1980), Oliveira et al. (1983), Belo de Oliveira (1986), Vieira & Oliveira (1988), and Vieira et al. (1991). According to Noce (1995), the difficulty to establish lithostratigraphic units acceptable for the whole Nova Lima Group is due to the intense deformation, alteration processes, and deep weathering associated with the lack of a more detailed cartography in many areas. In 1996, the DNPM and the CPRM concluded the Rio das Velhas Project, which aimed at mapping the Rio das Velhas Greenstone Belt in the Quadrilátero Ferrífero at a scale required for prospection and mineral exploration. Mapping was conducted on 27 sheets, at the scale 1:25,000 and summarized in a geological map at the scale 1:100,000. In this work, the rocks of the Rio das Velhas Supergroup were grouped in associations of lithofacies genetically related. The Nova Lima Group is formed by the following associations, from the bottom to the top: (1) metavolcanic-plutonic mafic-ultramafic; (2) chemical metavolcano-sedimentary; (3) chemical pelitic metasedimentary; (4) clastic metavolcano-sedimentary; (5) marine clastic metasedimentary (resedimented) association. The Maquiné Group is the top unit of the Rio das Velhas River Supergroup occurring restricted to the mid-east portion of the Quadrilátero Ferrífero. According to Dorr (1969), this group is composed by the following formations, from the bottom to the top: Palmital, constituted by sericitic quartzites, quartzose phyllites, and phyllites; and Casa Forte, originally defined by Gair (1962), constituted by sericitic quartzites, schists, and phyllites. In the Rio das Velhas Project, previously mentioned, the Maquiné Group was recognized as a non-marine clastic metasedimentary association presenting a coastal facies (Palmital Formation), and a fluvial one (Casa Forte Formation).
12
The Minas Supergroup was originally denominated as Minas “Series”, by Derby (1906). Since then its stratigraphic organization has remained essentially the same, composed by three Groups: Caraça, Itabira, and Piracicaba (Dorr 1969). This unit usually overlay rocks belonging to the metamorphic complexes and to the Rio das VelhasSupergroup in tectonic contact. The Caraça Group, base of this unit, presents the Moeda Formation in the lower part and the Batatal Formation in the upper part. The Moeda Formation contains quartzites
Mangabeiras Park
with intercalations of phyllites and conglom erate levels. Either ferruginous or carbonaceous sericitic phyllites predominate within the Batatal Formation. The intermediate unit consists of the Itabira Group constituted by a sequence of chemical metasediments, the basal Cauê Formation overlain by the Gandarela Formation. The Cauê Formation is composed of itabirite, dolomitic itabirite, ferruginous dolomite, and phyllite. The Gandarela Formation is formed by dolomites, dolomitic phyllite, and siliceous dolomite. The Piracicaba Group is the upper unit
presenting the following formations
from the bottom to the top: Cercadinho, Fecho do Funil, Taboões, and Barreiro. The Cercadinho Formation is characterized by the alternation of quartzites and phyllites, frequently ferruginous. Phyllites, dolomitic phyllites, and dolomite lenses form the Fecho do Funil Formation. The fine-grained
orthoquartzites found in the Taboões
Formation and the phyllites and graphite phyllites found in the Barreiros Formation have restricted occurrence. The Sabará Group corresponds to the Sabará Formation (Dorr 1969) ele-
Daniel Mansur
vated to the category of Group by Renger et al. (1994). It is formed by chlorite schists and phyllites, metagraywackes, conglomerates, quartzites, and rare ferriferous formations. Its rocks outcrop along practically the entire Quadrilátero Ferrífero, except for the Moeda Syncline. The Itacolomi Group, restricted to the southeast and south portions of the Quadrilátero Ferrífero, is constituted by quartzites, conglomerate
quartzites, and conglomerate lenses with itabirite, phyllite, quartzite, and pebbles of vein quartz.
The Espinhaço Supergroup occurs in the northeast portion of the Quadrilátero Ferrífero, represented by the quartzites from the Cambotas Range.
According to Crocco-Rodrigues (1991), the stratigraphic position of this unit, initially correlated with the
Tamanduá Group by Simmons & Maxwell (1961), has always been controversial, as it includes distinct rock sequences tectonically juxtaposed.
13
Application Dossier Geopark Quadrilatero Ferrifero Project In the regional geological context of the Quadrilátero Ferrífero, besides the stratigraphic
Itabitito Peak
sequence previously described, it is also important to mention the presence of basic and metabasic intrusive rocks which cut the supracrustal sequences and the granite-gneiss terrains, especially to the west of Belo Horizonte, as well as in the Caraça Range.
Miguel Andrade
2.3 – Geological history A variety of tectonic models have been proposed to explain the complex pattern for years. Among the main models, the works of Alkmim & Marshak (1998) should be emphasized. Based on results of structural studies and evaluating compiled data, they suggest
that the Quadrilátero Ferrífero has undergone four phases of
deformation. These authors present a summary of the tectonic evolution of this region: (1) Formation of Archean granite-greenstone terrains: the
Mangabeiras Park
most ancient crystalline rock basements are aged 3,200 Ma. All the fragments of continental crust from this time form the basement onwhich the sedimentary and greenstone successions were deposited between 2,800-2,700Ma (Rio das Velhas Supergroup). The granitoid plutonism created a classical Archean

granite-greenstone belt with granite-gnaisse domes surrounded Casa Bandeirante

2.4 –Mining history The region proposed for the Quadrilátero Ferrífero Geopark is
Morro Velho Mine Source
historically marked by the development of activities related to the extraction of mineral resources. In the 16th century, the Portuguese effort to conquer mineral wealth in the Americas and to accomplish fast success as the spaniards in Mexico, Peru, and Bolivia concentrated on two strategies: the ncessant search to access gold and silver reported by he natives, especially along the Paraguai and Amazon iver and the Bandeirantes¹ expeditions through the Brazilian middle-eastern hinterlands. History demonstrated that the second strategy turned out to be successful. A

considerable amount of the gold produced in colonial and imperial Brazil came from this region, occupied since the end of the 17th century by the research expeditions of precious minerals. In the region of the Quadrilátero Ferrífero, two events were remarkable: the research expedition of precious minerals carried by Fernão Dias and the discovery of gold in Ouro Preto. These events influenced the settlement in the Quadrilátero Ferrífero, which initially occurred along two main axes, Sabará (influenced by Fernão Dias‟s expedition) and Mariana and Ouro Preto (influenced by the discovery of gold in the Tripuí creek). These discoveries together with a series of expeditions that followed prepared the great phase of the gold explorations and the settlement in the Quadrilátero Ferrífero with the foundation of the villages of Mariana, Vila Rica de Ouro Preto, and Vila Real deSabará. Several hamlets and villages within or near the Quadrilátero Ferrífero had their birth associated with gold mining, such as: Caeté, Congonhas, Catas Altas, Santa Bárbara, Barão de Cocais, Cachoeira do Campo, Ouro Branco, Nova Lima, São Gonçalo do Rio Acima, and Piedade do Paraopeba, among others. Ferrand (1894) and Barbosa & Rodrigues (1967) call attention to the four phases of gold exploration in the Quadrilátero Ferrífero of which the first three happened during the colonial period, permitting decisively the settlement in the region; the last one occured during the imperial period using mechanized extraction techniques. ¹ Translator‟s Note: First Brazilian explorers of the 16th – 18th century who ventured through the hinterlands focusing on native slave-hunting and on the conquest of new land, gold and precious stones.

In the colonial period, gold exploration was limited to alluvial gold employing slave workforce and rudimentary techniques toextract the gold found on the earth‟s surface and on river beds. The works on river banks and terraces and in mountain valleys used pit workings. This method consisted of excavations in the shape of a funnel where the miner removed the soil to the point of the pebble bed. As the gold was found, the caves were deepened in order to reach the hard rock. In the workings on the mountain flanks (workings in eluvial and colluvial material), the miners used the difference in level to have streams of water flow through the whole mass, dragged, and collected underneath. Thus, in the first phase the extraction used to be carried Draw of mining – Rugendas 1824
out along the axis of the rivers where the gold was being discovered. As the supply of gold exhausted, the deposits on hillsides started to be explored up to terraces of 30 to40 meters
above the level of the river, characterizing the second
phase. In some places, a third phase happened with the exploration of terraces of 60 to70 meters above the river. During the third phase the gold content decreased. Rudimentary techniques were used in mines and the lack of means for
deepening the exploration resulted in decreasing
output. From the second half of the 18th century onwards, the population started to abandon the mines and to dedicate to other economical activities as agriculture, which was limited by the inappropriate conditions for its development, and trading. Several factors led to the decline of the mines: the economical policy adopted by the Portuguese crown itself with a confuse and repressive legislation, inadequate administration, lack of concern to improve mining techniques and individualism of the mine owners. ²Translator‟s Note: Literally, “the little cripple”. His nickname is associated with a debilitating painful disease which caused deformities in his body and eventually the loss of toes and fingers. Even suffering with the disease and body limitations, Aleijadinho continued to execute his works of art.
17
Application Dossier Geopark Quadrilatero Ferrifero Project The mixture of races and cultures in the colonial period turned the Quadrilátero Ferrífero into a civilizing, and cultural cradle,
permitting the appearance of an artistic movement linked to architecture, literature, and music. The baroque art
flourished especially with the masterpieces of Antônio Francisco Lisboa – known as Aleijadinho² - and Manuel da Costa Ataíde, observed in several towns of the Quadrilátero Ferrífero. In the field of music, the region also counted on renowned artists as Jose Joaquim Emérico. Moreover, the Quadrilátero Ferrífero was also the cradle of the first expressive literary movement in Brazil with the participation of Cláudio Manuel da Costa, Tomás Antônio Gonzaga and Alvarenga Peixoto. In the fourth phase of gold mining in the Quadrilátero Ferrífero (during the 19thcentury), more modern methods of sub-surface and surface mining were used. Gold production increased only after admission of foreign – mostly British – capital in the Brazilian mining industry in 1824. In 1810 the mineralogist and geologist Wilhelm Ludwig Von Eschwege was hired. Upon his arrival, he was assigned to evaluate the situation of the gold mines in Minas Gerais, study ways to improve the production as well as consider the possibilities to implant new mining techniques capable of recovering the decadent mining industry of the country. As specialists insisted that the mines were not exhausted and could still offer good results with the use of advanced techniques, the English identified the opportunity to found companies and acquired promising mines in Minas Gerais. The Imperial Brazilian Mining Association was the first to be established - in 1824 - and bought the gold mine Gongo Soco, in the region of Caeté. With the arrival of the English capital, the mining techniques used in the 18th century were replaced by the sophisticated machinery directed to the extractive activity, as crushers, and hydraulic wheels. However, at this very time, other economical activities attracted the attention of the population and the provincial government itself, particularly cattle raising, agriculture, and coffee plantation, the first Brazilian export product in 1831. The phase of iron forges occurred simultaneously to the fourth phase of gold extraction and even before it. Initially rudimentary, it was characterized by variations in the manner of melting, using from pans and home stoves to more refined methods. According to Rosiére et al. (2005), the iron mining activities in the region of the Quadrilátero Ferrífero (in Itabirito) already occurred during the gold cycle with the first attempts to exploit the enormous reserves through small iron industries. The metallurgy of iron in this period is not very well documented and Landgraf et al. (1994) suggest that it was influenced by the use of the African knowledge on iron extraction once they presented a rudimentary technique, efficient though.
18
From 1777 onwards, several factors led to a higher interest in the development of mines and iron forges (a millenary process of direct reduction of ore using charcoal in small-sized ovens) in Brazil. According to Azevedo & Paula (2003), the arrival of D. Rodrigo de Sousa Coutinho was relevant to Brazil. Being a skillful politician and a competent administrator, he took over the Ministry of Marine and Ultramarine Affairs from 1796 to 1803 and became therefore responsible for the colonial policy. Another important factor was the foundation of the Royal Academy of Sciences in Portugal in 1777, stimulating research to evaluate the economical situation of Portugal and its colonies. Furtado (1994) states that the main target of these studies was to diagnose the Portuguese delay in relation to other European nations, find the reasons and propose solutions. The arrival of the Portuguese Royal family in Brazil in 1808 was essential for the development of the metallurgy of iron, which received encouragement and financial support for the establishment of the first three units in the country, two of which in Minas Gerais: The Royal Iron Factory of Morro do Pilar and Patriotic Iron Factory in Congonhas in the Quadrilátero Ferrífero. In this period, the metallurgy of iron in Brazil had the contribution and experience of some experts as Manoel da Câmara Ferreira Bettencourt e Sá; the Swedish Carl Hedberg; the Germans Varnhagen, and Eschwege, who counted on the Crown‟s recommendation and financial support. The activities of mineral extraction, mainly gold, and iron, determine the present landscape of the Quadrilátero Ferrífero, being important to the development of its history and culture. The large number of towns and historical hamlets, mines and sites of mineral extraction, small agricultural areas, iron and steel factories, train stations, tourist attractions are elements that confirm the great cultural and historical value of the region of the Quadrilátero Ferrífero (Barbosa & Rodrigues 1967).

3. Listing and description of geological sites Fifty-five sites of natural, cultural, and historic interest, especially those that represent the geological history of the Quadrilátero Ferrífero and of the mining history of Brazil, have been recognized. For the first phase of implementation of the Geopark, a seletion of 29 sites – geological and non-geological - is considered (Map 2). The selection of sites was based on the recommendations by the Brazilian Commission of Geological and Paleobiological Sites - SIGEP and partially used the inventory made by Ruchkys (2007). SIGEP was established in 1997 with the objective of recognizing the Brazilian geological heritage. In order to understand the history of mining and of the geological evolution of the region, it is essential to emphasize the importance of the following sites.

4. Quartzites and basal conglomerate from the Moeda Formation – Moeda Range This site is located in the Moeda Range, around 17 km to the south of Belo Horizonte. It was formed in a context of relative global quiescence and existence of a recently consolidated Archean platform that originated the Minas proto-basin, initially with continental followed by marine sedimentation. The Minas Supergroup started to deposit at approximately 2.5Ga, along a passive-margin basin developed in the pre-existent continental platform. The first record regarding the opening of this basin is marked by auriferous and uraniferous metaconglomerates found in the basal part of the Moeda Formation. This unit was Moeda Range

5. Caraça Range and Sanctuary The Caraça Range is the generic name for a set of mountains that present the highest altitudes of the Quadrilátero Ferrífero, with the Sun Peak (Pico do Sol) reaching 2,072m a.s.l. The Caraça Range is composed essentially of quartzites from the Moeda Formation belonging to the Caraça Group. The Inficionado Peak, located in this mountain range, holds quartzite caves, among which the Centenário grotto, the world's largest in this lithology. The cave tunnels form a quadratic network of labyrinths reaching – 481m of depth of difference in level and a total of 3,790 m of horizontal projection (4,700m of linear development). Due to this characteristic, the Caraça Range is recognized as geological heritage of Brazil by SIGEP.

Itacolomi Peak The Itacolomi Group represents a typical deposition of fluvial environment and alluvial fans in narrow intermontane depression. The alluvial fans are sediments occurring typically adjacent to the mountainous areas. The quartzites from the Itacolomi were first described as new rocks by Eschwege, in view of their wide distribution and own characteristics, and denominated itacolumite or quartzite itacolomi. The Swiss geologist Dr. Heusser, climbed the Itacolomi Peak in 1859 and recognized carstic features in the quartzite.

The main lithotypes constitute the sandy and clayey sediments from the Fonseca Formation, probably formed in the Eocene. These deposits are covered by the ferruginous conglomerates (“canga”) from the Chapada de Canga Formation. The

fossiliferous record from the Fonseca Formation is characterized by a wide variety of Angiosperm families, of which the Melastomataceae and Mimosaceae constitute the most abundant families. The most remarkable fossil belongs to the Family Bombacacea – a relatively well-preserved flower, presenting prints left by petals and stamen (male reproductive organ of the flower). It is the only fossiliferous site of the Geopark.

For the purpose of assuring its profits, the Portuguese Crown instituted several fiscal measures related to the production, payment, and circulation of gold to control the quantities extracted in the mines. Within the systems adopted for collecting the taxes, the most significant is the Quinto, a tax charged by the Portuguese Crown correspondent to 20% of all gold founfound in the colony. Compared to the crown, trading attributed a much higher value to gold. Therefore, the Crown had

constantly to deal with problems such as smuggling, tax dodging, and forgery. Coin counterfeiting is an example of the multiple forgery tactics developed in the Colonial Period especially when the first melting were established (from 1724 to 1735). Inácio de Souza Ferreira, together with Manuel Francisco, and other accomplices, founded an illegal mint in a well-located country house in the Paraopeba Valley. Once equipped and structured, it soon started to produce gold bars and coins with genuine minting dies stolen from the official melting houses and considered useless. The country house where the illegal melting house of the Paraopeba Valley operated is extremely important for the history of mining and an example of the misconduct caused by the gold in the colonial period.
3. Patriotic Factory (Iron Foundry) As with mining, iron metallurgy also represents the vocation of the region of the Quadrilátero Ferrífero and the explorations of iron define the
Ruins of Patriotic Factory
landscape. Eschwege had the idea to build a plant toproduce iron at industrial scale. Therefore, he formeda private company to construct this plant that was named Patriotic Factory (Fábrica Patriótica). The construction started in 1811 and in 1812 the first iron was forged using a mallet at industrial scale. The ruins of the Patriotic Factory are preserved by the IPHAN as a historical testimony of the iron metallurgy

industry in Brazil. This site was recognized as a National Heritage Monument in 1938 as the first iron factory in Brazil.
4. Morro da Queimada The Morro da Queimada (“Burned Hill”), which is the birthplace of the city of Ouro Preto, is being transformed into an archeological park, where researchers will undertake excavation work that aims to improve the knowledge of the occupations during the Gold Cycle in Brazil. The IPHAN is responsible for this initiative. According to IPHAN director in OuroPreto and general coordinator of project, Benedito Tadeu de Oliveira, they intend to also to create a new tourist attraction for Ouro Preto.

5. Pedra Pintada Archeological Site The archeological site of Pedra Pintada with its cave paintings is located 3 kilometers from Vila de Cocais, Barão dos Cocais district. It was studied in 1843 by the Danish Naturalist Peter Lund, and more recently, by historians Alexandra Simões Siqueira and Janaína Fonseca Mota, who estimate that the paintings are 4,000 years old. There are 122 paintings made with mineral pigments (mostly iron toxides), divided in 3 panels, where animals are predominant, as well as weaponry. In 1998, the archeologist André Proust headed a UFMG and IEPHA team which copied over three thousand paintings, which are now part of the Museum of Natural History of UFMG in Belo Horizonte, and of the Museum of Man in Paris, France.
6. Tripuí Ecological Station Tripuí is considered one of the oldest places in the colonial history of Minas, where one can still find the remains of the old royal road that leads to Ouro Preto. It is currently one of the most importante natural conservation areas in Minas Gerais, being world renowned for hosting a rare animal, considered to be a “living fossil” and a relic from our biological past, Peripatus acacioi.

Gold Museum The former Gold Intendency and Melting House of Sabará, built in1721, is a beautiful genuine example of 18th century colonial architecture and now houses the Gold Museum. As one enters the museum the visitor get an exact impression of how miners lived at that time, from rustic engineering to utensils, and furniture. It is the only construction of its kind that is still standing in Minas Gerais. Its architectural style is typical of the 18th century. On the top floor pieces of furniture and religious imagery are in exhibition. On the bottom floor, where the pavements are made of pebbles, assorted pieces, models, and instruments are displayed, all related to gold and diamond mining. A press, brought to the building in the early 18th century for marking gold bars, is still at its original place. Gold Museum

D – Economic Activity & Business Plan 1. Economic activity The population of the area proposed for the Geopark is of approximately 3,154,506 inhabitants, and since the discovery of gold at the end of the 17th century to present the region of the Quadrilátero Ferrífero has the largest urban concentration of the state of Minas Gerais. In its northern part, the state capital of Belo Horizonte has
nearly 2.4 million inhabitants. The cities
of the region have a population of about 22% of the state population, and they are responsible for 26.8% of the GDP for the state of Minas Gerais. The Quadrilátero Ferrífero is the most important mineral province in the Southeast of Brazil, with mining being the basis for the economy of several cities that are part of it. Brazil has an important place in two of the most important minerals of the Quadrilátero Ferrífero: iron and gold; the country is the second largest iron ore producer in the world. In 2008, its production was 19% of the world production (IBRAM 2009). In 2006, Minas Gerais produced 70% of the iron ore in Brazil, with almost all the production being from the Quadrilátero Ferrífero. The Brazilian production of gold was 55 tons in 2008, which is nearly 2% of the world
Piedade Range
production. Minas Gerais is responsible for 39.7% of it. According to Foscolo et al. (2008), Minas Gerais has the largest concentration of operational mines in the world. In general, cities that are part of the Quadrilátero Ferrífero have a dynamic economy and have had, in the past few years, a growth of their Gross Domestic Product (GDP) above the national and state averages. The economy of the region is
strongly influenced
Miguel Andrade
by Belo Horizonte, which is responsible for around 73% of the GDP, which is mostly made up by the services and industry. As faras the Human Development Index (HDI) goes, most cities are at a mid-level and just a few of the cities like Nova Lima and Belo Horizonte are at a high level.

1.1.
Sources of financing
Sources of financing the Quadrilátero Ferrífero Geopark are from calls for the financing of projects and also from the establishment of partnerships. The projects listed in item I are financed by such partnerships and on the resources of public institutions of promotion. Significant support financial is supplied by the State Secretary of Science, Technology and Higher Education of Minas Gerais, through the Mineral and Metallurgic Pole of Excellence. In the second half of 2010 was started the delineation of the lines of support for the Federal Government of Brazil to the Geopark, through the Ministry of the National Integration. The Instituto Quadrilátero is able to attract national and international resources for the implementation and operation of Geopark.
2. Existing and planned facilities 2.1. Infrastructure The Quadrilátero Ferrífero Geopark is well located in relation to the main points of origin for tourism in
Brazil. Belo
Horizonte is 586km away from Sao Paulo, 434 kilometers from Rio de Janeiro, and 716km away from Brasília, and these are moderate distances, considering the size of Brazil. The capitals have airports with regular and charter flights. The Quadrilátero Ferríferoregion has two airports, one international (Confins), and another national (Pampulha). The International Airport of Confins is located between the towns of Confins and Lagoa Santa, 38km away from downtown Belo Horizonte; the airport has direct international flights to Lisbon, Panama City, and Miami. The two first destinations have flights five times a week, through TAP and COPA Airlines, respectively. The latter has four flights a week through American Airlines. There is also a stop to Buenos Aires (TAM/GOL/Varig), Paris (TAM), and Miami (TAM). The government of Minas Gerais is responsible for the largest road construction ever planned for Belo Horizonte, called Linha Verde. It is an adequation of the streets that connect downtown to the International Airport, which is now a freeway, so that this trip can be done in 35 minutes. The downtown airport of Belo Horizonte/Pampulha is used for general and regional aviation, and it has flights from the capital to several destinations in the state and in neighboring states. A special bus line links the two airports.

The Quadrilátero Ferrífero region is part of an extensive system of state and federal roads, making all the cities of the geopark accessible. As a rule, the cities of the Quadrilátero Ferrífero have basic infrastructure such as water, electricity, and public health care systems sufficient to supply local population, some of then nedding improvements, especially when facing the possibility of increased tourism. The tourism infrastructure tends to be concentrated in cities. The colonial towns, Ouro Preto, Ouro Branco, Mariana, Catas Altas, Santa Bárbara, and the cities of the Belo Horizonte metropolitan area, Sabará, Nova Lima, Rio Acima, and Brumadinho, are the main areas of infrastructure within the Geopark. There are several hotels, bed and breakfasts, restaurants, camping grounds, tourism agencies, local guides, as well as a diverse local commerce. Rural infrastructure is mostly made up of roadside businesses providing accommodation and family-owned restaurants.
42
2.2. Protected Areas The National System of Conservation Units - SNUC was created on July 18, 2000 by Law 9,985, and regulated on August 22, 2002 by Decree 4,430, was a response to the need to preserve the diversity of biomes, ecosystems, and species within the national territory. It is capable, therefore, of enabling the national preservation goals, allowing for the integrated management of protected areas. Conservation Units are divided in two categories related to the nature of its use, as: Full Protection Units, and Sustainable Use Units (Biodiversitas, 2005). In the area proposed for the creation of the Geopark the following conservation units associated to geological sites are present:
Mariana, Ouro Preto Belo Horizonte, Brumadinho, Ibirité, Nova Lima Caeté, Sabará Ouro Preto Barão de Cocais, Belo Horizonte, Brumadinho, Caeté, Catas Altas, Ibirité, Itabirito, Mário Campos, Nova Lima, Raposos, Rio Acima, Santa Bárbara, Sarzedo. Catas Altas, Santa Bárbara
2.3. Building the future The concept of the geopark proposed by UNESCO is innovative as it combines science, culture, and education to diversify and complement touristic offers, and it may be seen as a strategy for territorial development. Based on these premises, we present the construction of the present and the future of the Quadrilátero Ferrífero Geopark.
43
Application Dossier Geopark Quadrilatero Ferrifero Project
2.3.1. Quadrilátero Ferrífero 2050 Program The Department of Geology of the School of Mines - UFOP with the support of the State Secretary of Science, Technology and Higher Education of Minas Gerais has implemented the Quadrilátero Ferrífero 2050 Project (http://www.qfe2050.ufop.br/). It is a Center for Advanced Studies of the Quadrilátero Ferrífero created with the intent to promote, conducte, and publish studies and knowledge in the fields of Earth Sciences, mining activities, and sustainable development of the territory of the Quadrilátero Ferrífero.
2.3.2. Mining and geopark The Quadrilátero Ferrífero is one of the main mineral districts in Brazil and the world, and mining activities shaped its landscape, and are references in the area. In the geopark proposal, the concepts of geological potential and geological/mining heritage are considered to be complementary – therefore, the mining areas have their value recognized, and their legal rights respected. Considering that the mining companies have shown a growing concern to harmonize their activities with conservation, and that they have accounted for billions of dollars
invested in agreements for social-environmental responsibility and
environmental compensations, the initiatives of geotourism and geoconservation that include education and interpretation of the geological heritage might be developed with the support of these companies, and even using their properties. An example of how this is
already happening is the Center for Biodiversity Research and Conservation in the area of the exhausted mine
Córrego do Meio in Sabará, through a project of Vale mining company. The initiative is unprecedented in Brazil, and it consists of recovery and transformation of an old mine into a space to develop research and conduct
activities for environmental
conservation and recovery of areas that have suffered human intervention in the past. Aside from that, there is the decommissioning and recovery of the exhausted mines of Morro Velho (underground) and Águas Claras (open pit).
43
However, in relation to education of the general public, especially children, there is still the understanding that it all still remains to be done when it comes to interpretation and use of geological sites. In this sense, environmental education and interpretation programs should be proposed and developed for each site for this purpose, and they should include: (a) Implementation of geotourism paths integrating the sites; interpretative visits for schools of the towns that are part of the geopark; interpretative visits included in the touristic products of the towns involved. The observation of geological aspects is so much more interesting and profitable if the observation is pedagogically directed, and if locations of clear geological nature are used. Since these requirements are met, one of the purposes of geotourism has been achieved, which is to bring the non-profissional public closer to the
geological language,
making it to understand scientific observations. In this sense, the definition of geotourism paths-routes is a way to organize and integrate the educational possibilities of the Quadrilátero Ferrífero, showing the main spots to be visited by tourists. The routes help the organization of
specific
segments, to meet also specific demands. There already a few works that might help implement such tours. In 2008, the CPRM launched a site with a proposal for a virtual tour of the Quadrilátero Ferrífero, with indication of some of the sites proposed for the Quadrilátero Ferrífero Geopark. The product was developed within the
Ibero-American Mineral Routes Program and to
the territorial organization for the sustainable development of society – RUMYS and it is available online (http:// www.cprm.gov.br/estrada_real/index.html). The objective of this site together with the results of the research project financed by PUC Minas in 2006 is as follows: “Gold Route a proposal for geotourism-cultural routes in the Circuito do Ouro and Estrada Real in the context of the Quadrilátero Ferrífero”, is the basis for the creation and publication of routes. In 2003, the Department of Geology of the School of Mines UFOP launched the project “Minas High Lands”, which proposed routes integrated in the natural aspects of the Quadrilátero Ferrífero (available at http://200.131.211.7/terras).
44
Application Dossier Geopark Quadrilatero Ferrifero Project Another interesting proposal is presented by Liccardo (2007), which is
Antônio Liccardo
the creation of mineral tourism routes linked to a mineral tourism circuit, which is a variation of geotourism that reaches not only those who appreciate nature, but also those who appreciate, collect, and purchase minerals and gemstones, an area that has special economic importance in Minas Gerais. In the area of the Quadrilátero Ferrífero Geopark, the highlight is the production of imperial topaz – in Rodrigo Silva, a district of Ouro Preto - and for soapstone, which is used for adornments and handicraft. Aside from the routes, it is important that each site has an infrastructure that is capable to promote the geological or mining resources with the right interpretative materials and signaling made available, such as panels
Handicraft made of soapstone
and signs, and the production of audiovisual material to promote sites that are to be distributed in the cities that are part of geopark. The production of interpretative materials should consider the
expectations of each audience (local population,
students, and geotourists) in order to develop different support programs, making the scientific language associated with the mining, and geological resources accessible, so that these different publics can
appreciate and understand it. The geopark
already has folders and pamphlets available for some of the sites that are part of the proposal. The sites located in state parks have the Instituto Estadual de Florestas – IEF “tour guides” project, printed materials to publicize and increase tourism for the public to know, respect, and protect natural resources. It is also important to create panoramic observations points for the geological resources within the geopark, creating a special environment. Special attention should be paid to the main traffic routes where these points may allow an introduction to the significance of the resources of the Quadrilátero Ferrífero, explaining the landscape evolution.
45
(b) Creation and implementation of education projects for the schools that are part of Geopark: It is believed that learning through projects may favor the knowledge of the geology of the Quadrilátero Ferrífero by children, once the learning takes place through experience. To foster the knowledge of the territory by children, we are analyzing the possibility of establishing a joint venture with the Rocha Amiga Project (Friendly Rock Project), which was developed in Portugal, and is the result of cooperation between several universities and schools. The project aims to create consciousness in students about how important rocks are in their daily lives, supporting, and providing essential materials for their lives, from shelter, water, and substract to the development of plants and animals, and industrial and technological uses. The project can be adapted to the local reality, and involves new fronts like: customizing eco-friendly tote bags with geological themes, drawing contests, writing contests, and pedagogical experience with prizes. We intend to develop the project contemplating the following phases: establishment of partnership; establishing it in the towns of the region and their educational networks; creation of teaching materials and sending these to the schools; development of activities in the schools. Aside from the Rocha Amiga Project, we intend to develop other projects like “Geopark goes to school” and “School goes to Geopark”, based on the experiences of other geoparks. (c) Development of an integrated museum program for the museums that are part of the Quadrilátero Ferrífero and have collections related to the mining or geology: A difference between geoparks and other types of parks is their ability to make geosciences more popular; museums that have collections related to these themes must have an educational proposal to promote geological resources. These museums must work as an educational space to stimulate visitors to learn more about minerals, rocks, and fossils that register 4.5 billion years of Earth history. All these museums already develop educational programs, but these are not yet directed to the geopark, and therefore specific programs should be developed. The types of educational programs implemented will depend on the sizes of the museums, their financial resources, personnel availability, and type of collection catalogue. However, each museum should aim to maximize their educational purpose, and for that, the exhibit displays play a fundamental role. The exhibits should be innovative, attractive, and make visitors think, to be both pleasurable and educational. The Quadrilátero Ferrífero has a few museums associated with the history of mining or the geological resources, and out of these we highlight the Museum of Science and Technique of the School of Mines – UFOP, the Djalma Guimarães Museum of Mineralogy (that will be incorporated by the Museum of Mines and Metal, which is part of the Praça da Liberdade Cultural Circuit) in Belo Horizonte; the Museum of Natural History –PUC Minas, and UFMG; the Gold Museum in Sabará.

3. Análise do Potencial Geoturístico O Quadrilátero Ferrífero é uma área privilegiada do ponto de vista do The Quadrilátero Ferrífero is a privileged area as far as tourism planning goes in the
Handicraft made of soapstone
state of Minas Gerais. The reason for that is that most of its cities are part of the Circuito do Ouro as proposed by the SETUR, and by the Programa Estrada Real (Royal Road Program). The Circuito do Ouro is a series of roads that connect cities that are related to the history of gold mining, including Ouro Preto, Mariana, Congonhas, Sabará, Ouro Branco, Itabirito, Santa Bárbara, Santa Luzia, Caeté, Nova Lima, Belo Vale, Raposos, Cata Altas, Barão de Cocais, Bom Jesus do Amparo, Itabira, São Gonçalo do Rio Abaixo and Rio Acima. Parts of the Estrada Real - ER are included in the Circuito do Ouro presenting remnants of the Imperial Age, such as bridges, manholes, combined sewers, stone walls, and rails, pavements, old mines, as well as forgotten villages. State law nº. 13,137 from 1999 on the Pro-
Antônio Liccardo
gram to Incentivize the Tourism Potential of the Estrada Real refers to “the roads and its variants built during the 17th, 18th, and 19th centuries, in the states
territory”. Therefore, the term “Estrada
Real” refers to the union of three large pathways to the mines that were used by colonizers in different times. The routes of the three large pathways to access the mines – Old Path (Caminho Velho), New Path (Caminho Novo), and the Path to the Diamond District (Caminho para o Distrito Diamantino) – used the former roads, which might possibly date to native trails dating thousands of years. The Old Path connected São Paulo, from Piratininga, and its villages in the Paraiba Valley to the Velhas River region, and it was, in the earlier stages of gold discovery, the main route of access and supply of the gold mines. The New Path was hired by the Portuguese Crown and opened by Garcia Rodrigues Paes in order to connect Rio de Janeiro directly to the mines. The Path to the Diamond District connected two centers in the same captaincy of Minas Gerais: Vila Rica and the Arraial do Tijuco, center of diamond production. Another highlight of the tourism in the Quadrilátero Ferrífero is associated with the local food, which is one of the most typical and varied in Brazil, which is the result of a mixture of different cultural heritages from the people that helped to build this state. From the Portuguese influence, there is a preference for the simplicity of preparations, which highlight the natural qualities of products, and the sophistication of seasonings, and the delicate patisserie. African and native influences are also present. 47
A local drink is cachaça, sugar cane liquor brought to Minas by explorers and miners as a way to stay warm in the cold nights. Currently cachaça is made in farms all over the state, and is served as an appetizer or as a drink in bars. The mixture of cultural heritage of the people that helped make the state has also left behind beliefs and signs in the practices of local communities. Tourists from all over the country and the world are attracted by the regional festivals of Minas Gerais, which through celebrations, reenactments, masses, and vigils showcase all the religiousness of its people. The parties of the African immigrants were incorporated in Minas Gerais, especially through the sisterhoods of Nossa Senhora do Rosário.Congado, which mixes African traditions with elements of Portuguese-Spanish and native dance, and popular representations, was created through the permanence of characteristics of African religious rituals, adapted to the cult of God and the saints as depicted by Catholicism. The Divino, Nossa Senhora da Conceição, São Pedro, and São João festivals are important parts of the lives of locals (Rebio, 2005). During the Holy Week, in the towns of Ouro Preto, Mariana, Congonhas, and Sabará, colorful made from pavements of sawdust, representing the Passion of the Christ, is represented. The jubilee of the Piedade Range is an event to honor the patron saint of Minas Gerais. The carnival takes over the streets in many cities, with the carnival character of “King Momo”, caricature groups, and samba schools. The “ora-pro-nobis” festival and often called “the poor man‟s meat” due to its high protein content, is organised in Sabará, during the month of May. In Itabirito, every year there is the
Pastel do Angu festival, dedicated to celebrate a deep-fried
savoury pastry made out of cornmeal in the month of June. The pastry
GoldMuseum - Sabará
or Pastelmay be filled with beef, chicken, dried salted cod fish, or banana hearts. Concerning still tourism, the capital Belo Horizonte has a rich architecture in the modern style: the architectural complex of Pampulha (Igreja de São Francisco de Assis, Museu de Arte,Casa do Baile, and the Iate Tênis Clube), oneof the main landmarks of the city.
José Israel Abrantes
The complex wasdesigned by architect Oscar Niemeyer and built in the 1940s, and it became the most daring accomplishment of the government of Juscelino Kubitschek, then the mayor of Belo Horizonte. It is registered as a historical site by the state and federal Heritage Institutes, the series of buildings is a reference in modern architecture in Brazil and worldwide. The combination of cultural and environmental factors in the Quadrilátero Ferrífero makes it an adequate destination for ecotourism, as well as for cultural, scientific, and geotourism.

4. Overview and policies for the sustainable development 4.1. Promotion of the geopark concept in the Quadrilatero Ferrifero region We intend to increase awareness of the Quadrilátero Ferrífero Geopark, with the publish of information and concepts, to make it easier to understand, as well as to increase public participation. For that, technical-scientific events and workshops will be conducted with local communities. Aside from that, traveling photography exhibits will happen in the towns included in the Geopark, to display its rich geological resources and their significance.
4.2. Strenghtening and creation of international, national, and regional partnerships We intend to develop actions to widen the network of strategic partners of the Quadrilátero Ferrífero Geopark in the territory. For this purpose, we will formalize them through joint ventures of technical cooperation, or partnerships with the mining industry and with local government, so as to provide the geosites with touristic and educational infrastructure. Seeking cooperation through a network that promotes integrated actions, and strengthens the geopark concept, formal partnerships through cooperation agreements will be developed with the Geopark Araripe, as well as with other Brazilian states that are seeking candidacy: Serra da Bodoquena Geopark, and Campos Gerais Geopark. About geoparks outside Brazil, we intend to establish partnerships with the geoparks that have already been visited by the Quadrilátero Ferrífero Geopark Promoting Group, out of which we highlight: Reserve Geologique de Haute Provence (France), Madonie (Italy), and Naturtejo (Portugal), to promote an exchange of experience.
4.2.1.
Promotion of local development
We intend to develop actions that value local products and craftsmanship, to promote territorial cohesion. We will focus especially on those that directly relate to the geological resources: soapstone and itabirite. Several institutions are active in Minas Gerais with programs for training, qualification, technical assistance, and quality control of products: SEBRAE, SENAC, and CETEC. The current programs and projects developed by these institutions that relate to the geopark region will be assessed. 49
4.2.2. Making geotourism more dynamic To make geotourism more dynamic, we intend to implement the geotourism routes suggested by the project funded by PUC Minas (2006) and Serviço Geológico do Brasil – CPRM (2008), as well as structuring a route where sites of mineral interest will be prioritized, as suggested by Liccardo (2007). We also intend to create some circuits for visiting mines that developed throughout history and that are now abandoned, such as Morro da Queimada Mine in Ouro Preto and Morro de Santo Antonio in Mariana. For that, some areas will be selected to have interpretative panels, which will also be placed on some roads. Through a collective effort the cultural and touristic resources of the Morro Velho and Córrego do Meio mines will be made more dynamic. To make geological knowledge easier for tourists, support material such as folders, guidebooks, and catalogs will be created or reprinted. Professionals that will work on the Geopark will be trained through partnerships with the Tourism departments of PUC Minas, UFMG, and UFOP.
4.2.3. Developing educational programs We intend to develop, launch, and contribute to educational projects adequate to the different levels of education. In this context, we should highlight the development of the Projeto Rocha Amiga in a way adapted to the reality of the Quadrilátero Ferrífero Geopark territory, and the contribution to educational actions that have already been developed by museums, which are situated in the Geopark. To provide learning quality on the geological resources, the following programs will be implemented: “Geopark goes to school”, and “School goes to Geopark”. To develop the educational programs, we will establish partnerships with higher education institutions, with the development of extension projects.
4.2.4. Promoting geoconservation The process of inventory of the geological sites of the Quadrilátero Ferrífero will continue, as well as the proposal of new sites for the Comissão Brasileira de Sítios Geológicos e Paleobiológicos – SIGEP (Brazilian Committee for Geological and Paleobiological Sites). Communication and partnerships with environmental agencies will be strengthened, so as to follow up on the impact on the sites described. Partnerships with mining companies will be strengthened to promote recovery of degraded areas, to be used for tourism and education. 50

1. Scientific Support Some of the most important research and education institutions of the Southeast of Brazil are located in the area proposed for the geopark, such as UFMG, UFOP, and PUC Minas. These Universities have several undergraduate and graduate courses that can provide support to geopark, as well as develop research, and extension projects. There are also other institutions that have demonstrated an interest in the geology of the Quadrilátero Ferrífero, from other parts of Brazil, among which we may highlight USP, UnB, UNICAMP, UNESP Rio Claro, and UFRJ. The natural and cultural richness of the Geopark have been constant source of research and monitoring through covenants, projects, and contracts between the educational and research institutions, and Conservation Units administrations, and local government. The results of these works are made available as to supply local and regional demands, and have informed decisions for development policy, through partnerships between NGOs, government agencies, the private sector, and educational institutions. There is a great number of doctoral theses, master‟s theses, and undergraduate theses that deal with the geology of the Quadrilátero Ferrífero, and other related topics.
2. Governmental Programs: Circuito do Ouro, Estrada Real The region is part of two touristic products that are already well-defined, and complement each other: the Circuito do Ouro (http://www.circuitodoouro.org.br/) and the Estrada Real (http://www.estradareal.org.br/). The Circuito do Ouro (Gold Circuit) is one of the products of tourism regionalization public policies in Minas Gerais, and the region is often given, according to the demands of the cities that are part of it, projects and actions for tourism road signs, training, and improvement courses for tourism services, awareness, creation of a strategic development plan, creation of specific tours, and promotion as a tourist destination. The Instituto Estrada Real – IER has a series of initiatives for the promotion of the integrated development of tourism in the Estrada Real (Royal Road), creating business opportunities for local industry.

3 National and international scientific relevance The Quadrilátero Ferrífero is world renowned for its scientific importance of Pre-Cambrian geology. Aside from that, its mineral resources are a record of significant steps in the mining history of Minas Gerais and Brazil. Natural resources in the Quadrilátero Ferrífero are part of several protected preservation areas, which include rock formations (related to the geological resources), river courses, waterfalls, and native vegetation of varied ecosystems like Brazilian Tropical Savanna (Cerrado), fields of altitude in ranges, and remnants of the Atlantic Rainforest.
4 UNESCO presence in the geopark The area proposed for the geopark is recognized by UNESCO for its historical, cultural, and biological importance. Several cities of the Quadrilátero Ferrífero are recognized as Brazilian historical and cultural heritage, like the cities of Mariana, Sabará, Congonhas, and Ouro Preto, with the last two being considered world heritage since they preserve one of the largest amounts of colonial architecture and monuments of Minas Gerais baroque. In 2005, UNESCO recognized a part of the Man and Biosphere Program the Espinhaço Biosphere Reserve which occupies a 30,700 km2 area, and includes almost the entire area proposed for the Quadrilátero Ferrífero Geopark. The region has been recognized by research work in identification of biodiversity conservation priorities. Developed for all Brazilian biomes within the National Program for Biological Diversity Conservation (PRONABIO), of the Ministry of the Environment, with co-funding by GEF, these research indicated more than 300 priority areas throughout the country, one of them the Espinhaço Range (SEMAD, 2005). 4.1. Local development The Quadrilátero Ferríferois undoubtedly one of the richest and most diversified regions in the world. Its geological, geomorphological, historical, and biological importance justifies the adoption of measures that promote its territorial development in an integrated way, to respect these resources.
57
The recognition of the area as a UNESCO Geopark, in a heavily mined area, will be remarkable for Minas Gerais and Brazil, as it will reflect the importance of the establishment of a territorial development model that respects mining activites as well as guarantees conservation of resources, and local development through activities connected to tourism and education. With the creation of the Quadrilátero Ferrífero Geopark with the actions already developed by the Espinhaço Biosphere Reserve, important areas of human and economic development will benefit. Among these we might mention folk art and tourism, which combined work to increase the quality of living for several communities, promoting citizenship, and cooperation. These activities were mentioned in the application document for the creation of the Espinhaço Biosphere Reserve. Folk art enables economic development through a view of a social economy that focuses on creating jobs and income. In the geopark region, folk art is expressed through crafts that use natural resources, among which we should highlight the use of rocks from waste dumps of abandoned mines, such as soapstone and itabirite. These products are clearly associated with the geopark, and might become more widely traded with its creation. Several other products featuring the geopark might be created and sold: stuffed rocks and minerals, artifacts and jewelry, themed foods, among others. These products may be developed with the support of institutions that have programs for training, qualification, technical assistance, and quality control of products, among which we highlight the Support Service for Micro and Small Business - SEBRAE, National Service of Commercial Learning - SENAC and the Fundation Center for Technology of Minas Gerais - CETEC.. 4.2. Cooperation with existing geoparks or those being created in Brazil Considering that Brazil has, as of 2009 only one UNESCO geopark, the Araripe Geopark, it is fundamental that strategies for integration and cooperation between these are created, promoting the exchange of experiences, and the development of integrated and joint programs. The government of the state of Ceará, where the Araripe Geopark is located, tries to encourage the establishment of other geoparks in Brazil. The Quadrilátero FerríferoGeopark has a strategic geographical position in the continental position of Brazil, and can therefore assume an integrative role, helping widen the network of geoparks in Brazil, and forming and effective network of geoparks in Brazil, and in Latin America. As new geoparks are created in Brazil, the proposal for integration also allows for the exchange of information, knowledge, and experiences among these geoparks, promoting cooperative research, conservation, and the publicish of Brazilian natural resources, as well as promoting sustainable development.

Application Dossier Geopark Quadrilatero Ferrifero Project 4.3. Potential for contribution to the World Network of Geoparks The Quadrilátero Ferrífero Geopark is proposed in an area that has several active mines, which is a unique situation. The idea is that the geopark may promote the development of the territory in an integrated manner, guaranteeing alternatives for the communities once the mines are exhausted. The unique characteristics of the geopark might allow for the creation of valuable knowledge for the configurations of geoparks all over the world, with the development of actions that integrate conservation of the resources with their exploration. The team responsible for the proposal intends to invite geoparks of the world for cooperation, as well as to take part in, and promote technical-scientific and cultural events, such as workshops, congresses, seminars, and festivals. The Quadrilátero Ferrífero Geopark is proposed for a territory where the historical occupation, social development, and actions for conservation of environmental resources have all come together to create a favorable environment for the development of research and the exchange of experience.
