Scientists studying rare earth and critical elements now have a solid foundation for future research, as detailed in a special volume of the Society of Economic Geologists. This review volume, featuring several papers authored and co-authored by the U.S. Geological Survey, provides a comprehensive review of the current state of knowledge for rare earth and critical elements in ore deposits.

In addition, on March 30th at 1:00 PM EDT, American Geosciences Institute (AGI) will co-host a webinar titled Underpinning Innovation: The Science and Supply of America's Critical Minerals and Materials. USGS speakers include Larry Meinert, the program coordinator of the USGS Mineral Resources Program and Steve Fortier, the director of the USGS National Minerals Information Center. In addition, Rod Eggert, the deputy director of the Critical Minerals Institute, Ames Laboratory will be a featured speaker.

This webinar is based on a March 3rd Congressional briefing organized by AGI on behalf of the Mineral Science & Information Coalition. The webinar will address the efforts being taken at the federal level to ensure a steady supply of critical minerals and materials.

The special volume, entitled "Rare Earth and Critical Element in Ore Deposits," represents an important contribution to our understanding of where, how, and why individual critical elements occur and should be of use to both geoscientists and public policy analysts. While the papers in this volume provide an overview of the state of knowledge concerning the economic geology of rare earth and critical elements, they also demonstrate the lack adequate data on the occurrence of these elements in many deposit types.

Critical minerals and materials are key components of the innovation economy. Minerals are a part of almost every product we use on a daily basis, either as the raw materials for manufacturing processes or as the end products themselves. Advanced technologies for communications, clean energy, medical devices, and national security rely on raw materials from mines throughout the world.

The concept of element criticality is useful for evaluation of the fragility of commodity markets. This fragility is commonly due to a potential risk of supply disruption, which may be difficult to quantify because it can be affected by political, economic, geologic, geographic, and environmental variables. For instance, in 2010, China curtailed exports of rare earth metals and sparked major concern about the security of global supply chains for a range of vital minerals and materials.

Critical elements may be recovered either as primary commodities or as by-products from mining of other commodities. For example, nearly 90 percent of world production of niobium (Nb) is from the Araxá niobium mine (Brazil), whereas gallium (Ga) is recovered primarily as a by-product commodity of bauxite mining or as a by-product of zinc processing from a number of sources worldwide. Critical elements that are solely produced as by-product commodities pose a particular supply risk because their production is tied to other markets and thus fluctuations in their supply can be independent from their demand.

Rare earth elements are a focus of this volume because price spikes of these commodities over the past several years have created broad interest. As demonstrated in the papers in this volume, ore-grade enrichment of REEs can occur in a variety of deposit types.

Note the bright red patch on the wolf's hindquarters in this thermal image of a captive wolf at the Grizzly and Wolf Discovery Center in West Yellowstone. This is where fur was shaved to replicate the loss of fur associated with sarcoptic mange. The fur will eventually grow back. USGS scientists are examining thermal imagery of wolves as one step in assessing impacts of sarcoptic mange on the survival, reproduction and social behavior of this species in Yellowstone National Park. All research animals are handled by following the specific requirements of USGS Animal Care and Use policies. Researchers at the USGS Northern Rocky Mountain Science Center and their partners place thermal remote cameras near deer and elk carcasses in Yellowstone National Park to capture images of wolves with mange feeding in the wild. Red-colored blotches in the thermal images reveal areas of hair loss from which wolves with mange lose heat. Researchers at the USGS Northern Rocky Mountain Science Center and their partners place thermal remote cameras near deer and elk carcasses in Yellowstone National Park to capture images of wolves with mange feeding in the wild. Red-colored blotches in the thermal images reveal areas of hair loss from which wolves with mange lose heat.

During winter, wolves infected with mange can suffer a substantial amount of heat loss compared to those without the disease, according to a study by the U.S. Geological Survey and its partners.

Using a remotely triggered thermal camera to capture vivid and colorful images, scientists gathered body temperature data from mange-infected gray wolves in Yellowstone National Park and compared that to a sample group of healthy captive wolves with shaved patches of fur to simulate mange-induced hair loss. Using these data, scientists were able to quantify the level of heat loss, or energetic costs, during the winter months.

Results show that a more severe mange infection could increase heat loss by around 1240 to 2850 calories per night which represent roughly 60-80 percent of the average wolf’s daily caloric needs.

“That lost heat has to be replaced, otherwise the wolves’ core body temperatures would be getting colder,” said Paul Cross, USGS ecologist and lead author of the study. “To replace that lost heat wolves would need the equivalent of about two to four extra pounds of elk meat per day.”

Sarcoptic mange, present in one of 10 known packs in Yellowstone as of 2015, is a skin disease caused by a mite that burrows into the skin, causing irritation and scratching that then leads to hair loss. Researchers engineered the remotely-triggered thermal camera for use in Yellowstone to record the surface temperatures of wolves with and without mange-induced hair loss. Those images could then be compared with images from healthy, captive wolves. In addition, field crews observed or photographed all radio-collared wolves and their pack mates for the purpose of recording infection status.

The study also found that increased wind speed was a more significant factor in heat loss than colder temperatures. To compensate for the extra heat loss, infected wolves would need to increase food consumption in addition to other daily energy demands for survival. For wolves with mange this is more difficult as hair loss and depressed vigor leaves them vulnerable to hypothermia, malnutrition and dehydration, which can eventually lead to death.

Data from GPS-collared wolves in Yellowstone indicated that wolves with mange reduce daily movement distances depending on the degree of infection. In addition, the wolf with the most hair loss became more active during the day than during the twilight hours, which is opposite behavior of a healthy wolf.

“By definition, parasites drain energy from their hosts. In this study we estimated just one portion of the energetic costs of infection,” said Cross. “Even when parasites do not kill their hosts they are affecting the energy demands of their hosts, which could alter consumption rates, food web dynamics, predator-prey interactions and scavenger communities.”

Mange was introduced into the Northern Rockies in the early 1900s by the Montana state wildlife veterinarian in an attempt to help eradicate local wolf and coyote populations. The disease persists in coyotes and foxes and once wolves were reintroduced into the ecosystem in 1995-96, they appeared to be free of mange until 2002.

The article “Energetic costs of mange in Yellowstone wolves estimated from infrared thermography” is published in Ecology.

The study is a collaborative effort between the USGS, Pennsylvania State University, University of Western Australia, Yellowstone National Park, University of Wollongong, NWB Sensors Inc. and Montana State University.

Hot Days Can Trigger Yosemite Rockfalls

USGS Newsroom - Mon, 03/28/2016 - 11:00
Summary: After more than three years of monitoring the towering granite cliffs of Yosemite National Park, scientists have new insights into a potentially important mechanism that can trigger rockfalls in the park. Although many conditions can trigger rockfalls, some rockfalls are more likely to happen in the hottest part of the day, during the hottest part of the year.

After more than three years of monitoring the towering granite cliffs of Yosemite National Park, scientists have new insights into a potentially important mechanism that can trigger rockfalls in the park. Although many conditions can trigger rockfalls, some rockfalls are more likely to happen in the hottest part of the day, during the hottest part of the year.

Rockfalls in Yosemite are common and part of the natural process of erosion, but they also pose hazards to park visitors. Improved understanding of this thermal triggering mechanism may assist the National Park Service in managing rockfall hazards in the park.

To explain this phenomenon, U.S. Geological Survey and NPS geologists placed sensitive deformation and temperature gauges in a crack behind a large, partially detached slab of granite clinging to a Yosemite Valley cliff.  The scientists found that daily heating and cooling of the rock surface caused the crack to open and close by nearly half an inch. The resulting stress can cause such cracks to grow, destabilizing the rock slabs to the point where they fall, in a process called exfoliation.

According to Brian Collins, USGS geotechnical engineer and coauthor of the study, “Our research provides clear evidence that thermal effects can move large slabs of rock and that these movements, over time, can lead to rock falls.”

“Summertime rockfalls have been something of a mystery,” said Greg Stock, Yosemite park geologist and coauthor of the study. “With this work we now have a plausible explanation for why they happen.”

The full report, “Rockfall triggering by cyclic thermal stressing of exfoliation fractures,” is published in the current issue of the journal Nature Geoscience, and is available online.
