RMAG July Short Course Unconventional Resource Assessment and Valuation (URAV) Bryce Kalynchuk, Rose & Associates Rose & Associates’ short course focuses on a staged investment approach for dealing with low permeability resource size and value characterization of candidate multi-well projects. URAV emphasizes the need to develop the participant’s competency in the use of probability, uncertainty, and aggregation to assess and develop unconventional resources. The premise for this short course is that sound estimation of key engineering, geotechnical, and economic parameters is essential for maximizing profitability. Type curves and sequential aggregation techniques are discussed. Composite mapping strengths and chance assessment guidelines for tight sands, carbonates and shales are provided. Due to uncertainty and the huge capital outlays at risk, unconventional resource characterization requires a staged, probabilistic approach conducive to more informed decision-making and portfolio management.

BOARD OF DIRECTORS MEETING 17. The Educational Outreach Committee is planning a booth for a science fair in November and continues to work on making contacts at schools and recruiting volunteers. In honor of the On the Rocks fossil fish collecting trip to Wyoming this month, June’s geologic news is related to new fossils discovered in Australia. A new species of herbivorous dinosaur was discovered in New South Wales, Australia. The Cenomanian ornithopod, Fostoria dhimbangunmal, was an early duck-billed dinosaur. The specimen was found in an opal mine and was preserved entirely in opal. Those sound like some shimmery fossils!

PRESIDENT’S LETTER By Tom Sperr

Fun With Big Iron Is there no adult supervision in your company? So get out there, touch some iron. It helps keep you honest and motivated. For when you do go to the well, I have collected a few rules that you might remember. On the well-site everything is a snake and all those snakes are poisonous. You can get hurt, so take care and don’t get in the way. Everything on a rig is heavier than you think. Always look up - nothing on the ground is going to fall on you. If a hand asks you to do something, he is messing with you. There is no such thing as a key or extender. If the crew needed a key or extender they could find them. Don’t smell or taste anything that you did not bring with you. Steel toed footwear is a fashion statement on a rig. There is nothing to paint if you don’t have toes. If you see everyone running from the rig, get ahead of them. Always show up with a box of donuts for the doghouse. If you fail the drug test, while the rest of the crew has passed, you have a real problem and should seek professional help. Take care of your car keys and cellphone in the outhouse as there are no fishing tools for these objects.

Going out on a well can be a joy. Granted, as an office geologist it’s pretty easy; you witness a test or a logging run, look at a few samples and swap lines with the company man. I took our young son with me to see the Frontier sandstones drilled on a wildcat north of Rawlins, WY. The rig broke down on our way out there and we stayed for several days in Rawlins in a motel waiting on repairs. Ben thought this geology stuff was a pretty cool job; a pool to play in and pizza every night. We also spent a couple of cold, starry nights in the sand dunes north of Rawlins sleeping in the back of my truck after we resumed drilling. And I’ll never forget watching from the rig floor a thunderstorm flash lightning as it walked its way across eastern Montana, or coyotes howling at sunset while hiking the backside of Teddy Roosevelt National Park near our rig. We really should take time out of our busy office life to get out to the field. It’s sobering when you pull up and see all the equipment and people on site and realize this was just a spot on a map in your office last week. Is this really the best place to drill? Did you do everything you could to pick the right location? Why did anyone listen to you?

PRESIDENT’S LETTER can. The two best vehicles to take to the rig are a rental car and a company car. The only thing that can go farther than a 4X4 is a company car. Don’t ask where: you can find a good vegan meal or a good glass of pinot noir, or where the nearest Starbucks is. The best steak in town is often in the gas station. Just because the bars in the next state are open an hour later is not a good reason to visit them. A passing nod at the rancher on the road is a big ‘Howdy’ in Wyoming. Remember these other Wyoming rules: only open one car door at a time, sit in the corner of the bar where you can see the front door, speed limits are merely suggestions, and no, those oysters are not fresh and not from the ocean. Hot dogs can be roasted at the flare line, but beware of condensate. And always, always, don’t forget your phone charger. Have a good visit and be sure to show up with the donuts.

Challenge yourself to be warm enough in North Dakota in January; it’s not possible. The plug in front of your motel is not for your Tesla. You will be longer at the rig than you think. The common rule is to multiply any time estimate times 2 and add 2 more. Remember 2n+2 where ‘n’ may be minutes, hours or days. Take plenty of underwear. If you wanted to have a family, you shouldn’t have gone into the oil business. No, they don’t shut down for Thanksgiving, Hanukkah or Christmas. Cows don’t die on locations. Look for the drag marks behind them and see where they come from. All dead cows on locations are prize cows, which is why the cow was dragged there. Don’t lend the mud-logger money, it only encourages them. “We don’t do it that way in Texas” is not an excuse. Prognoses are like models. All are wrong and some are occasionally useful. Just because the water truck got through that puddle doesn’t mean you

LEAD STORY

THE WESTERN GRID, EXPLAINED BY GREG BUNCE, MAR 11, 2019

Gunter was not just a mathematician; he was also an English clergyman, a geometer, and an astronomer. He made several contributions to society, but we’re going to focus on his invention of the Gunter Chain in 1620 (Fig 2). The Gunter Chain, which was used for surveying, was quickly adopted as a statutory measurement in England and in the British Empire. What made it so popular was its ease of measuring and surveying plots of land for legal purposes. The Gunter Chain measures 66 feet in length and contains 100 links, making it very portable and convenient when working with English units. Measuring an acre (a standard British parcel) was as easy as laying out 10 square chains. When working with smaller plots of land, you’d simply divide the links by 100,000 to get the acres. Additionally, a statute mile was 80 chains.

Have you ever wondered why the patterns of development in the Western United States are so orthogonal (i.e., “right-angled”)? Pan around a map and you’ll see the confines of the grid just about everywhere. Grid-like development is nothing new — it can be traced back to early developments in the Middle East. But, why is it so prevalent in the West? It turns out this gridiron pattern is connected to a 17th-century mathematician, the Treaty of Paris, and Thomas Jefferson. Yup, there’s definitely a connection here, which also helps explain the West’s notoriously wide streets and big city blocks, as well as our nation’s entangled dependence on feet, yards, and miles (i.e., the United States customary units). Read on and we will explore the Western Grid more.

THE SURVEY CHAIN

Let’s start with the previously mentioned 17th-century mathematician: Edmund Gunter.

LEAD STORY

FIGURE 3: Northwest Territory

thirteen colonies, a large swath of land, referred to as the Northwestern Territory (Fig 3), was ceded to the United States. This was good news for a new nation carrying a sizable amount of wartime debt. Fortunately, the largely uninhabited Northwest Territory could be divided and sold off in sections (parcels) to generate revenue for the new nation. Though, first, this land had to be surveyed. The early American Congress further solidified the acre as the official unit of land measurement with the Land Ordinance of 1785 and the resulting Northwest Ordinance of 1787. These ordinances provided the framework for public lands and the procedures for organizing territorial lands west of the Appalachian Mountains.

»»CONTINUED FROM PAGE 14

Because of its ease in calculations, the Gunter Chain was quickly adopted and became widely used for surveying and land management records. In fact, it was so popular that it made its way across the Atlantic with the early colonists. The acre, noted in the Articles of Confederation (1781), was declared the standard unit of land measurement for the new nation. The Gunter Chain made a huge impact when it was developed, and we can still see its lasting effect as we begin to look closer at the western United States grid.

STANDARD UNITS OF MEASURE (THE ACRE)

Okay, let’s jump ahead to 1783 and the Treaty of Paris. At this point in American history, the thirteen original colonies had just pulled off the seemingly impossible and defeated the British Empire, ending its colonial rule. This treaty marked the official end of the Revolutionary War and the beginning of independent American governance. In addition to the

New RMAG Publication! Subsurface Cross Sections of the Southern Rocky Mountain Basins In 1977 RMAG published Subsurface Cross Sections of Colorado, a compilation of stratigraphic cross sections from all Colorado basins. This publication has been a valuable resource for geologists wanting to establish a basis for stratigraphic correlations. Well logs were presented on all cross sections, which was very helpful in understanding the log response for the different stratigraphic picks. During the 41 years since this publication, numerous wells have been drilled and digital logs now allow cross sections to be easily enhanced with color. In this update of the 1977 publication, we have expanded this volume to the southern Rocky Mountain basins. Some of the cross sections in this volume are timely in that there are emerging plays associated with the basin and stratigraphic interval represented in the cross sections.

LEAD STORY

FIGURE 4: PLSS Principal Meridians

the present-day Public Land Survey System (PLSS) (Fig 4). This system was originally proposed by Thomas Jefferson and was mandated by Congress to oversee the cadastral surveys of the public lands. Essentially, it was set up to facilitate the transfer of federal lands to private citizens. The Bureau of Land Management (BLM) is the official record keeper of the surveys. Over the past 200 years, almost 1.5 billion acres have been surveyed into townships (and ranges) and sections. These surveys were conducted primarily west of the original thirteen colonies and north of Texas (Texas has Spanish roots and Spanish land grants). Presently, areas of Alaska are still being surveyed. As with any measuring system, you need a starting point. Within each PLSS system, this is where a defined meridian line (north-south) meets a defined base line (east-west). Most of Utah is within the Salt Lake Meridian PLSS system for which the base and

FIGURE 6: Townships, Ranges and Sections

Roosevelt. All official surveys in Utah have an underlying reference to one of these two points. In other words, every township and section in Utah is numbered off of these locations. Other PLSS states have their own unique meridians (Fig 4). Townships are made up of thirty-six square miles, with each square mile known as a section. Sections are eventually subdivided down to an acre by way of half sections, quarter sections, quarter-quarter sections, etc. (Fig 6). An acre, again, is simply 10 square chains, and there are 640 acres in a section (a square-mile) or 40 acres in a quarter-quarter section. Hence the phrase, “40 acres and mule” is all you needed to be self-sufficient. No matter how you shake it, though, land measurements in the West are consistently divisible by the magic 66-foot Gunter Chain. You’ll see its effect everywhere. This measuring unit was so successful because it made the math easy — and many early surveyors had a shaky grasp of mathematics and they were required to work quickly. These early surveyors typically placed a permanent monument at section and quarter-section corners. These markers are still heavily used today and are the starting point for almost every Western legal description you’ll encounter, including land deeds (the transfer of private property), water rights (well

OUTCROP | July 2019

locations), and taxing areas, as well as municipal annexations and, consequently, voting districts. Because of this, it has been difficult for the US to adopt the International System of Units (the modern metric system). It is precisely this survey pattern that explains why the western United States is so orthogonal. Although the grid is not unique to the West, it’s certainly at the core of all land sales and, as a result, it influences many development patterns. Let’s look at a few examples.

»»CONTINUED FROM PAGE 18

THE WESTERN GRID

One of the more dominant patterns you’ll see in the West is the rectangular city block. You could argue that the Mormon pioneers helped carry this development pattern west from Missouri with their Plat of Zion (Fig 7) and their subsequent establishment of more than 700 communities. Contrast this pattern with the pre-PLSS pattern of the early colonial settlers in Boston (Fig 8). Large city blocks are a common theme in the West. They typically vary between 198 feet, 330 feet, and 660 feet (which is 3, 5, and 10 chains). Often, two sides of the block are 660 feet, with the adjacent sides being 198 feet or 330 feet. Looking at Portland

(Fig 9), their blocks are unusually small for the West at 198 feet x 198 feet. On the other side of the spectrum, Salt Lake City (Fig 9) is known for having the largest blocks in the West at 660 feet x 660 feet. Blocks are more rectangular in San Francisco (Fig 9) and Phoenix (Fig 9), as they measure 660 feet x 198 feet and 660 feet x 330 feet, respectively. If you have ever tried to cross the street in downtown Salt Lake City, you know our intersections are

Vol. 68, No. 7 | www.rmag.org

extremely wide. You’ll see the Gunter Chain’s lasting mark at these intersections as well. Looking at Portland (Fig 9) and Salt Lake City (Fig 9) again, you’ll notice two variations of the chain. Salt Lake City (Fig 9) has large intersections that are based on two chain lengths (132 feet), whereas in Portland and San Francisco intersections measure half a chain (33’). In Phoenix (Fig 9), you’ll notice intersections measure one full chain length (66 feet).

is the disguised grid. These are often large communities where the land is typically purchased by the section (or more) and then is made to feel less grid-like. Two good examples of this pattern are Sun Lakes (Fig 11) and Sun City in Arizona. As you move through these communities, you forget that you’re on the grid. It’s remarkable how a few key points in history have permanently affected the growth and development patterns in the western United States. It’s also interesting how these same decisions have made it difficult for us to turn our backs on the imperial-based measurement system (i.e., United States customary units). So, the next time you’re out wandering the

SECTION LINES AND ADDRESSING Another notable mention are “section line roads.” These roads are laid out in a one-mile by one-mile grid pattern that follows the section lines.

Mudrock Sedimentology and Sequence Stratigraphy Core Workshop

Dates: Sept 10-11, 2019

Locations: USGS Lakewood and Stratum Reservoir, Golden Instructors: Stratigraphix Prerna Singh, Ph.D., Sven Egenhoff, Ph.D Ali Jaffri, Ph.D Abstract: Many factors affect the volumetric and flow capacity of mudrocks including (i) organic content type, maturity, distribution (ii) mineralogic composition - ductile vs. brittle thus affecting the geomechanical properties and (iii) current day stress fields - imperative for decisions including orientation of horizontal wells and completion design. Sedimentology and Sequence Stratigraphy can provide an understanding and explain the systematic variation of the abovementioned factors. This two-day course will use lectures, core, thin-section and well-log data to highlight critical details impacting understanding resource distribution as well as planning landing zones and completions. We will examine four public and three proprietary cores across seven formations (Wolfcamp, Eagle Ford, Mancos, Mowry, Bakken, Niobrara, and Haynesville). High-quality photographs of key features in proprietary cores will be provided as part of course material (no other photography will be permitted).

‘The Longmont Detachment Mega-Landslide, Fact or Fiction’ By Ken Kittleson

KEN KITTLESON: I have been a geologist for 47 years, obtaining my B.S. and M.S. degrees from the University of Iowa. The first 13 years were spent working in the oil and gas business for such companies as Exxon, Placid Oil, American Petrofina and Stauffer Oil and Gas before the OUTCROP | July 2019

downdip up to 1.6 km. (1 mi.) above other well-cemented, unfaulted volcanic ash detachment surfaces. Secondly, a two-stage post-Laramide Longmont Detachment was discovered following the identification of a resistivity geophysical well log on the boundary between a 187 sq. km. (72 sq. mi) eastern area (ELD) and a 345 sq. km. (133 sq. mi.) western area (WLD). This discovery precipitated a post-Laramide Longmont Detachment age with the ELD developing from transverse movement on the updip Longmont Fault, located just south of Longmont, Colorado, followed by a later WLD detachment as a classical landslide. This talk will also explain the development of such well-known geological features southeast of Boulder, Colorado as Marshall Mesa, Davidson Mesa (the overlook onto Boulder from the Boulder Turnpike) and the “White Rocks” outcrop next to Boulder Creek.

Ten years ago, I proposed the discovery of a 531 sq. km. (205 sq. mi.) landslide detachment east of Boulder, Colorado termed the Longmont Detachment. This theory was met with skepticism and difficult to comprehend and ultimately accept within a normal geologist’s perspective, where a superficial landslide of 26 sq. km. (1 sq. mi.) maybe considered incredible. This detachment theory was added to the list of mechanisms, including strike-slip faulting by the USGS to explain the area’s complex faulting. The results of a 5-year geophysical well log investigation detail several significant new discoveries that characterize how the area’s unique stratigraphic and structural geology have allowed such a massive structure to develop. The two major ones include a single-event volcanic origin for the study area’s upper Cretaceous section, explaining how uniform plates up to 160 m. (525 ft.) thick and 12.4 sq. km. (4.8 sq. mi.) could detach and then move

collapse of the business in 1986. Following the acquisition of a M.S. degree from Colorado State, I worked as a geologist in the environmental business for 22 years until my retirement in 2011. Since then, I have devoted my time to geological and structural research as well as 28

volunteering in the Denver Public School’s Balarat Outreach Program where I teach 3rd grade students about nature and geology. I was the recipient of RMAG’s “Distinguished Public Service to Earth Science” 2013 award for this work.

Sequence Stratigraphy and Geologic Reservoir Characterization of the Niobrara in the Northern San Juan Basin By Walter Nelson

OUTCROP | July 2019

lithostratigraphic units with significant sequence stratigraphic surfaces interpreted. Numerous extensive outcrop locations (in and around Pagosa Springs, Piedra, and Durango, CO) along with three new cores along the CO-NM border form the foundation for sequence stratigraphic interpretation of the Niobrara marine cycle in this study. Establishing and applying a sequence stratigraphic framework to any section creates consistent reference standards for communication, research, and further correlation. Comparisons of lithologic and geochemical data from equivalent strata between the northern San Juan Basin and DJ Basin reveal significant differences in the timing and style of source-rock deposition (and associated low-oxygen conditions). The sequence stratigraphic framework also emphasizes tremendous lateral facies changes within the basal Niobrara section (i.e. Fort Hays Limestone to Tocito Sandstone). Once refined and applied, this stratigraphic framework can be used for predicting the distribution of reservoir and geomechanical properties in addition to enhancing the current understanding of the Niobrara and the Western Interior Seaway.

In the northern San Juan Basin, the Niobrara Formation is represented by the upper half of the Mancos Shale (the Smoky Hill Member and Cortez Member). This section is generally equivalent to the Niobrara Formation along the Colorado Front Range. Although the Fort Hays Limestone is absent west of Pagosa Springs, the C Chalk and B Chalk are well-expressed as two resistant bench-forming calcareous units in the northern San Juan Basin. These two calcareous units have also been established as prospective hydrocarbon targets by operators in the area. Calcareous facies equivalent to the A Chalk were not deposited in the northern San Juan Basin due to siliciclastic dilution during the regressive latter half of the Niobrara marine cycle. The overall third-order Niobrara marine cycle includes these members of the Mancos Shale: the Juana Lopez, Montezuma Valley, Smoky Hill, and Cortez Members. The Smoky Hill Member sits just above the basal Niobrara unconformity in most of the study area, and the entire section also has greater thickness and siliciclastic content than its equivalent farther east along the Front Range. Despite these differences, the four Niobrara fourth-order cycles (T7a-R7a thru T7d-R7d) have been assigned to distinct

I went to the Denver Gem and Mineral Show last September on the very last day. Among the treasures I uncovered, on a bargain table no less, was a fist-sized chunk of fault breccia healed by strained clots of authigenic calcite and dolomite. There, my eye was immediately drawn to a scintillating, ruby-red crystal of cinnabar nestled tightly in a vug. For $10 I added this piece to my collection and I have been perplexed by it ever since. It is a real beauty, but is it poisonous? I’ll try to answer that question here. Cinnabar, mercuric sulfide (HgS), is the only important ore mineral of mercury. The name cinnabar is derived from the Persian zinjirfrah and the Arabic zinjafr, both of which translate to “dragon’s blood” (Bonewitz, 2005). Cinnabar forms in association with near-surface volcanic hydrothermal systems. Cinnabar is a highly visible mineral, occurring as deep blood to ruby-red crystals and aggregates that are so striking, they have attracted human attention for at least 5 millennia. Consequently, humans have mined cinnabar

Vol. 68, No. 7 | www.rmag.org

and its most notorious component, mercury (a.k.a. quicksilver), for a very long time. To the ancient world, mercury represented a magical substance with occult powers. Cinnabar was also used for cosmetic and medicinal purposes. We now know that mercury is one of the most toxic natural substances and this has led to vast reduction in mercury production over the last few decades. Places of historic cinnabar mining, as well as places where mercury was used, remain as sites of environmental contamination. Diagnostic properties for cinnabar include its bright red color (and congruent scarlet streak), low hardness (2-2.5) a high-specific gravity (8.1 g/cc, due to the Hg content), perfect cleavage on {10bar10} and adamantine (brilliant) luster (Johnsen, 2002). Cinnabar is highly birefringent. Also, cinnabar, at 3.08, has the highest refractive index of any mineral – a characteristic that gives it that extra sparkle. Cinnabar is a sulfide that belongs to the higher-symmetry rhombohedral subset

(Hermann-Mauguin symbol 32) of the hexagonal crystal system. Most cinnabar occurs as granular, massive or earthy incrustations and surface coatings. When euhedral crystals occur, they display rhombohedral forms, often as penetration twins (Klein, 2002; Johnsen, 2002). Most cinnabar is pure HgS, although some substitution of Se and Te for S is noted. Metacinnabar, a high-temperature polymorph stable above 344°C, is isometric and it lacks the bright red color of cinnabar, occurring as metallic gray to black in color with a black streak (Klein, 2002). Cinnabar is found at the margins of large, low-temperature, hydrothermal systems and occurs as pore-filling impregnations in sandstones and veins and fracture fills adjacent to volcanics, fumaroles and hot springs. Commonly, cinnabar mineralization is discovered in association with relatively young volcanic systems. Cinnabar is “low-temperature” hydrothermal because it forms at less than 200°C. The host rocks can OUTCROP | July 2019

be sedimentary, igneous or metamorphic. Mercury has relatively high solubility in alkaline hydrothermal fluids. Cinnabar yields liquid mercury – quicksilver – after being heated in a furnace. The mercury escapes from the furnace as a vapor that is then captured and condensed into liquid mercury (Kesler, 1994). The liquid mercury is then funneled into standard storage flasks that hold 76 pounds of the material. Mineral associations of cinnabar include mercury, pyrite, marcasite, realgar, stibnite, antimonite, quartz, chalcedony, barite, dolomite and calcite (Klein, 2002; Johnsen, 2002, Mineral Data Publishing, 2005). Mercury is slightly concentrated in organic matter reservoirs. Hg is released as a vapor phase during combustion of coal and petroleum (Reimann and Caritat, 1998). Cinnabar is well-known to be associated with petroleum hydrocarbons. Small amounts of petroleum have been observed in California Coast Range cinnabar deposits and elevated mercury concentrations occur in

It has been demonstrated that introduction of volcanic hydrothermal fluids created cinnabar deposits with petroleum bitumen (Peabody and Einaudi, 1992). Cinnabar has been exploited by humans many thousands of years. Hundreds of kilograms of pulverized cinnabar were used in a burial tomb for dozens of people discovered in Palencia, Spain. The closest cinnabar mine was 160 kilometers away, indicating a “significant and intentional work process.” The cinnabar, which perfectly preserved the bones, was dated to 5,000 years ago (Martin-Gil et.al., 1995). Employing the bacteriostatic properties of mercury compounds revolutionize the science of embalming. In the 1800s, William Hunter concocted a mixture of vermilion dispersed in turpentine, lavender oil and chamomile oil which was injected into the femoral arteries of corpses (Martin-Gil et.al., 1995). Cinnabar has long been recognized as a coloring agent. Because it has a hardness of 2-2.5 on the Mohs scale, cinnabar is easily ground into a fine powder which makes it easy to mix into formulations. Many of the ancient cultures that coexisted with volcanoes independently discovered, processed and utilized cinnabar for ceremonial and artistic uses (Geology.com, 2019). Ancient Romans used cinnabar in paintings and frescoes. The Mayans used cinnabar to decorate burial chambers and the bodies of

revered dead. Indigenous Americans used cinnabar as a pigment for ritual use. Cinnabar was used in Greece, Spain and Turkey. For all these cultures, cinnabar was exploited for its rich, red color. Cinnabar was identified as the coloring agent in red inks and pigments in pre-tenth century Chinese manuscripts using Raman Spectroscopy (Clark et. al., 1998). Cinnabar is the major component in the red artists pigment known as vermilion, and “cinnabar” and “vermilion” have been used interchangeably for centuries (Gettens et. al., 1972). Cinnabar continues to be used as vermilion in artist’s paint, although less toxic substitutes (like cadmium red) are now favored. Cinnabar has been used in Chinese traditional medicines for thousands of years. Cinnabar is still an ingredient in 40 traditional medicines still in use (Liu et. al., 2008). Medicinal use of cinnabar has a long history in India and Europe as well. The Swiss physician and alchemist Paracelsus recommended mercury-based antiseptics to treat new diseases like syphilis OUTCROP | July 2019

and typhus (Martin-Gil et.al., 1995). Ironically, cinnabar was taken orally or rubbed on the skin to promote health and immortality (Bonewitz, 2005). We now know that these practices were likely to create the opposite of their intended effects. The economies of gold and silver production were tightly linked to mercury, hence cinnabar, availability. This is because of the ability of mercury to dissolve silver and gold, particularly important for removing finely divided flakes and dust. Adding liquid mercury formed an alloy by dissolving the silver and gold. Afterward, the mercury is removed by boiling (Jones, 2011). This important use of mercury expanded greatly in the 1500s and 1600 by spread of the patio process for recovering gold from ore. In this process, gold ore is spread onto a flat patio, covered with mercury and then crushed Kesler,1994). The ore crushing process was initially conducted by having people walk over the mix, but it didn’t take long for this effort to disable or kill the workers due to Hg toxicity (Jones, 2011). Mules

then replaced people. The mercury, laden with dissolved gold, was then recovered and boiled off leaving a gold residue. The patio process became the method of choice for extracting gold in the New World. Because the only source of cinnabar at the time was Almaden, Spain, the Spanish Crown exacted great wealth from the trade in cinnabar. The cost of quicksilver for gold production was 1/5th of the gold proceeds to the Crown (Kesler, 1994). The California gold rush would not have been as prosperous if not for the development of cinnabar mines south of San Jose, California. These mines, which started producing mercury ore in 1845, became more valuable than any of the gold mines discovered later. Because mercury was readily available from these mines, and at low cost compared to sources in Mexico and Spain, California gold mining became a much more productive enterprise (Jones, 2011). In more modern times, mercury has found widespread use in batteries, fluorescent lamps, mercury

Vol. 68, No. 7 | www.rmag.org

switches, thermometers and barometers, detonators, chlor-alkali (caustic soda and chlorine) production plants, gold ore processing and dental amalgams (Reimann and Caritat, 1998). Mercury use has been phased out in many applications because of the adverse effects of mercury pollution on the environment. For instance, Hg use in batteries has been severely reduced (Gray, 2009). Dental fillings used to be made of an amalgam comprised of 50% mercury, 35% silver and 12% tin with the remainder being copper or zinc (Kesler, 1994). In the modern world, mercury-based dental amalgams have been superseded by polymer resins and other nontoxic substitutes (Geology.com, 2019). We now know that mercury is among the most toxic of natural substances to be encountered by humans. Mercury is a central nervous system poison. Depending on exposure variables, mercury poisoning can lead to permanent damage to the brain, kidneys and developing fetus. Brain function effects may include irritability, shyness, tremors, changes in vision or hearing and

memory problems (ATSDR, 1999). Mercury toxicity depends on the form of mercury (pure liquid, inorganic Hg or organic Hg), the route of exposure (ingestion, inhalation or absorption) and the dose, the duration and the frequency of exposure. Inorganic mercury in cinnabar has been used in Chinese traditional medicines for 2000 years. Liu et. al. (2008) studied the toxicology of cinnabar through different organ systems and concluded that cinnabar is insoluble and poorly absorbed by the gastrointestinal system but that it accumulates in the kidneys where renal dysfunction may follow long-term use. Inorganic mercury is simply less toxic (but not non-toxic) than liquid or organic forms. A particularly sinister manifestation of mercury toxicity occurs when Hg is methylated by bacteria and this organic mercury bioaccumulates in the food chain, particularly in shellfish and fish (Chaline, 2012). Methylmercury becomes increasingly concentrated in higher trophic levels of the food chain. That is why the fatty tissues of long-lived fish such as shark and swordfish OUTCROP | July 2019

are enriched in mercury and there are health advisories regarding exposure to meals from these fish (ATSDR, 1999). Although cinnabar is widely distributed on Earth, only a handful of localities have it in economic abundance or yield exceptional specimens (Gettens et. al., 1972). The Almaden district in Spain has been the site of cinnabar extraction for more than 2000 years – it was a place that liquid mercury dripped from the walls. This locality still yields valuable specimens and ore which makes it – possibly – the oldest continuously working mine on Earth (Bonewitz, 2008). Other important localities for cinnabar include Peru, Italy, Idria in Slovenia, Uzbekistan and the Hunan Province in China (Johnsen, 2002; Bonewitz, 2005). In the United States, important localities include New Almaden and New Idria in California; Humboldt and Pershing Counties, Nevada; Terlingua, Brewster County, Texas; and Kirby, Pike county, Arkansas (Mineral.net, 2019).

my cinnabar sample toxic?” The answer is ‘Yes, it is’. As with other minerals that may be poisonous, the trick to collecting and curating them is limiting potential exposures. As for my cinnabar sample, I have it stored in a box where it cannot collect, or generate, dust. Whenever I handle it, which is rarely, I wear nitrile gloves. I don’t sniff it. And, I never, never, never eat it. Tips for handling any potentially toxic substance, mineral or otherwise, include: Avoid inhaling dust, especially when breaking. Do not heat the material. Wear chemically-resistant (nitrile) gloves when handling. Do not get the material on your skin. Do not ingest. Always wash your hands. Have fun with your cinnabar, just don’t treat it like Cinnabon.
