Dr. Robert Hazen Robert M. Hazen, Senior Staff Scientist at the Carnegie Institution’s Geophysical Laboratory and Clarence Robinson Professor of Earth Science at George Mason University, received his B.S. and S.M. in geology at the Massachusetts Institute of Technology (1971), and the Ph.D. at Harvard University in earth science (1975).

He is author of 350 scientific articles and 20 books, including Genesis: The Scientific Quest for Life’s Origin. The Past President of the Mineralogical Society of America, Hazen’s recent research focuses on the role of minerals in the origin of life, the co-evolution of the geo- and biospheres, and the development of complex systems. He is also Principal Investigator of the Deep Carbon Observatory, a 10-year project to study the chemical and biological roles of carbon in Earth’s interior (http://dco.ciw.edu). Hazen is active in presenting science to nonscientists through writing, radio, TV, public lectures, and video courses. In addition, Hazen is a professional trumpeter and is a member of the National Gallery Orchestra and the National Philharmonic.

The Great Oxidation Event Origins of Earth’s Most Colorful Minerals

Robert Hazen’s colorful presentation will focus on his research in the new field of “mineral evolution,” which focuses on the changing diversity and distribution of mineral species through 4.5 billion years of Earth history. The most startling finding of mineral evolution is that two-thirds of all known minerals are the consequence of life, most dramatically by the rise of atmospheric oxygen about 2.5 billion years ago. Recent studies on the evolution of minerals containing elements sensitive to oxidation state, including As, Co, Cr, Cu, Hg, Mo, Ni, S, and U, reveal that many of the most beautiful minerals on Earth could not have occurred prior to the rise of oxygen, and would thus not occur on a nonliving world. Hazen will contrast the mineral evolution of Earth, Mars, and the Moon, and reveal why many of our most beautiful minerals are unambiguous signs of life.

Dr. Peter Megaw Peter has been a passionate mineral collector since first setting foot in Santa Eulalia in 1977.

He moved to Tucson in 1979 and quickly joined the Tucson Gem and Mineral Society, serving in most roles (except Treasurer) over the years. Dr. Megaw took on the job of Exhibits Chair for the Tucson Show in 1984, a job he has kept for most of the last 30 years, giving him the opportunity to visit most of the world’s major mineral museums with a special eye out for what they should bring to Tucson.

His mineral collecting has come to focus exclusively on minerals of Mexico. He won the Desautels Trophy in 2006 for the Best Case of Minerals at the Tucson Show for a case of Mexican Minerals and is is one of the first Carnegie Mineral medal awardees. He has also been awarded the Romero Trophy three times for the best Mexican specimen on exhibit in the Tucson Show. He frequently contributes to top mineral publications and has received multiple awards. He is photo-moderator for submissions on Mexico to Mindat and co-moderator of the FMF Mineral Forum, often with tongue planted firmly in cheek.

Adventures in Mexico’s Great Specimen Mines

Megaw’s 35 years of “Mineral Collecting Adventures in Mexico” have been a fringe benefit of exploring Mexico for silver-lead-zinc and silver-gold deposits, which “necessitates” frequent visits to established mining districts to see what’s new. Sometimes he finds only a few flats of nice specimens in Mapimi or Charcas, but sometimes he’s presented with unique opportunites like being one of the first to crawl into the Cave of the Giants at Naica. Mostly it’s being in the right place at the right time whether underground, on the surface, or in the air. “Exploring in the shadow of the headframe” gets you there often. Enjoy this geological, historical, cultural, mineralogical and exploration context for a few localities that have been the source of several major specimen recovery projects.

Dr. James Houran Dr. James Houran grew up around fossils, gems and minerals. Mentors in the Central Illinois Gem & Mineral Club laid the foundation of a passion that continues to grow. Jim holds a Ph.D. in Psychology and has authored over 100 articles on personality, sensation and perception. He regularly appears in the media talking about his research, including the Discovery Channel, A&E, BBC, National Geographic, NBC’s Today Show, USA Today, New Scientist, Psychology Today and Forbes.com.

He is a member of the Mineralogical Association of Dallas (MAD) and a life-long collector specializing in “thumbnail” gem crystals. Jim is an active member of the hobby. He hosts the DVD series “Mineral Perspectives: Thumbnails” from BlueCap Productions, authors publications for Gems & Gemology, Rocks & Minerals, Lapis and the Mineralogical Record, and cocoordinates many featured exhibits for the Denver Gem and Mineral Show, the Munich Show and the Tucson Gem and Mineral Show.

Thumbnail Specimens: Little Treasures Collecting and Competing Thumbnail specimens are traditionally assumed to be an American niche, but these little treasures have a long if somewhat quiet history in the hobby and span worldwide interest. Houran has studied many of the top thumbnail collectors in the hobby past and present and has amassed his own collection of world-class thumbnail mineral specimens. This presentation reveals the often misunderstood motivations and focus behind these collectors and demystifies the allure of why small specimens of top quality can have such a big impact, individually and as a group.

The Arkenstone Open House Friday Evening

Evan Jones Longtime mineral collector and dealer Evan Jones was born in Arizona in 1961 and began collecting minerals at the age of 9. The son of well known mineral collector and author Bob Jones, he frequented museums, attended mineral shows, field collected and visited mineral dealers from an early age. After earning a degree in Geology from Arizona State University, Evan worked as a mineral wholesaler for Bitner’s Inc. from 1986 to 1998, then struck out on his own as a mineral dealer. In 2012, he formed a new mineral dealership, Unique Minerals, Inc., which specializes in fine minerals for collectors and can be seen at most major mineral shows. He helped organize the “Arizona Mineral Treasures” exhibition at the 2012 Tucson Gem & Mineral Show, organized the recent supplement to the Mineralogical Record magazine “Mineral Collections in Arizona,” and is on the advisory board of the University of Arizona Mineral Museum in Tucson, Arizona. His collection of minerals from Arizona is considered to be one of the finest in private hands, unless you ask Les Presmyk, who also has one of the finest collections in private hands.

The Milpillas Mine, Sonora, Mexico - A Modern Bonanza

In the summer of 2007 Evan was contacted by an itinerant miner from Sonora, Mexico who said he had azurite and malachite specimens for sale.

They met and Evan was dazzled by several small but high quality plates of lustrous azurite crystals and velvety malachite pseudomorphs from a new location. Thus began his journey of dealing in copper minerals from the Milpillas mine in Sonora, Mexico, an underground mine which exploits a partially-oxidized porphyry copper deposit. During the past seven years, Milpillas has produced an unbelievable suite of finely crystallized and colorful minerals including world-class azurites, amazing malachite pseudomorphs, the finest brochantite crystals ever found, well crystallized coppers, cuprites, barites and several rare copper species.

Les Presmyk Les Presmyk, Principal Mining Engineer for SRP in Phoenix, and along with his wife, Paula of 38 years, are both Arizona natives.

He received his B.S. degree in Mining Engineering at the University of Arizona (1975), working underground at the Magma Mine in Superior and the San Manuel Mine for Magma Copper for 11 years. He has worked for SRP for almost 28 years, dealing with coal and nuclear fuel contracts and mine issues for SRP’s generating stations.

Les started collecting minerals at the age of 10. He collected world-wide until 1980, when he decided to specialize in Arizona specimens. Paula is the thumbnail collector. They started their business, De Natura, in 1977 and today are long-time dealers at the Tucson and Denver Shows. He has been a member of the Tucson Show Committee for 29 years. His collection of Arizona minerals is considered to be one of the best in private hands, unless you ask Evan Jones, who also has one of the finest collections in private hands.

Red Cloud - The World’s Greatest Wulfenite Locality

While it may be a bit presumptious to proclaim the Red Cloud as the world’s greatest wulfenite locality, it is certainly in the very top echelon. Since the mine opened in the 1870’s, the value and beauty, along with its unique color of the wulfenite specimens, have enticed miners to preserve them. As dealers like Ward’s, George English and Foote were getting their starts in the late 1800’s, specimens from Arizona, and especially Red Cloud wulfenite, figured prominently in their ads and offerings. For the past 140 years, the Red Cloud has been a source for orange to orange-red to red wulfenite, enticing hundreds of field collectors to try their luck, and always setting the bar by which all other wulfenite localities have been judged. The mine has continued to produce up the early part of the 21st century and not many localities can claim to have produced specimens over three centuries!

Dr. David Mustart David A. Mustart, Professor of Geology at San Francisco State University, received his B.Sc. in Geology at University of British Columbia (1965) and his Ph.D. in Experimental Petrology on the origin of pegmatites, with Richard H. Jahns at Stanford (1972). Dr. Mustart worked in precious metal mining districts in the Yukon and Northwest Territories, and for the past 42 years has taught courses in geochemistry, mineralogy and ore deposits at San Francisco State.

David set his sights on geology at age 6, when he recognized his passion for collecting minerals in British Columbia. He has developed his current teaching and research collection by concentrating on mineral associations from major ore deposits, both through leading trips to active mines in the Western U.S. and by acquiring specimens from sites world-wide.

Origin of Precious Metal Deposits - Mines that Produce World-Class Collectible Specimens

World-class specimens of gold and silver are found at only a handful of sites worldwide, and from only a few ore deposit types. At these sites, a combination of critical geologic conditions have converged to produce masterpieces like “The Dragon�, with exquisite forms such as dendrites, leaves, wires, herringbones, hoppered octahedra, and arborescent sprays.

Dr. Mustart will explore why such sites are so rare, explaining both the unique combination of geologic processes that must occur, and the few times in Earth’s evolution when events impacting the continents led to the formation of these remarkable precious metal deposits.

Dr. Robert Cook Longtime gold specimen collector and retired geology professor Robert B Cook attended Colorado School of Mines where he obtained his degree in Mining Engineering in 1966 and continued his education at the University of Georgia where he was the first person to receive a Ph. D. in Geology in the university’s 200 year history.

After graduation he worked in mineral exploration for several years, ultimately ending up at Auburn University where he taught for 35 years, during 22 of which he was Head of its Department of Geology. Over his career he conducted exploration programs as a consultant in a variety of foreign countries and essentially all western states. He has also acted as consultant for the U.S. Department of Defense, NASA, the United Nations, and the United States Department of Justice.

He retired from Auburn in 2007 at which time the university established an endowed chair in his name. Bob continues to prospect gold specimens in both Nevada and Colorado, works with the Tellus Science Museum where much of his gold collection is on loan, and is striving to develop a geological field camp near Leadville, Colorado.

Gold Rush - Crystallized Gold Specimens from Classic California Localities Few minerals are as widely recognizable as gold, and undoubtedly some of the best gold mineral specimens originate from California. Of the California mines, Eagles Nest in Placer County and the Mockingbird and Colorado Quartz Mines in Mariposa County stand out for the spectacular quality of specimens that have been found there.

Dive into explanations of the different mine geology and see some of the most important specimens found at these three classic California localities.

Anthony Fraser Mr. Anthony (Tony) Fraser was born and raised on the Central Victorian Goldfields.

At a very young age, he developed a keen interest in rocks, minerals and fossils. Anthony played a pivotal role in the discovery of several new mineral species, including Ulrichite, Selwynite and Whycheproofite. He graduated as a Geologist in 1990 and worked for several years in the industry as an Exploration Geologist and Mine Geologist throughout Australia. He launched his career at his first Tucson Show in 1994 when co-founding Crystal Classics, and in the early 2000s he founded Gold Nugget Export to focus on prospecting. Anthony is currently actively involved in several mining entities and mining projects both in Australia and Internationally. Anthony is also Chairman and Senior Curator of the National Dinosaur Museum in Canberra, Australia.

Gold Fever - Monster Gold Nuggets of Victoria’s “Golden Triangle”

The Central Victorian Goldfields of South Eastern Australia were discovered in 1851, and soon rose to international prominence with the discovery of the largest gold nuggets ever documented. Of all the “Monster Nuggets” known worldwide, around 90% were unearthed on the Central Victorian Goldfields, the largest being the “Welcome Stranger” with a gross weight of 2520 Troy ounces, or just over 172 lbs! The lure for riches and a fascination for Monster Nuggets is ongoing today, and with the advancement of modern metal detecting technology many prospectors scour the Central Victorian Goldfields in hope of hitting the jackpot. But how are such large masses of gold formed? What type of geological environments are such Nuggets found? Why is Central Victoria such a prolific Nugget producer? All this and more shall be revealed in the talk “The Monster Gold Nuggets of the Central Victorian Goldfields.” (above) Fraser with a nugget now on display at The Perot Museum (left) With his “improvised meteorite-spotting mobile”
