Rare Earth Element Deposits in the Southeast Mojave Desert
In an effort to better understand domestic resource potential, the USGS is investigating the genetic relationship between rare earth element deposits at Mountain Pass, California and Music Valley (Pinto Mountains, California) and extend these studies across a 130-km long belt of alkaline Proterozoic rocks in the southeast Mojave Desert. Such a combined study would significantly improve our...
Lithium Clays as a Source of Lithium and a Buffer for Lithium Concentration in Brines
We are collaborating with academic and industry geologists to develop a predictive model for lithium partitioning between lithium-bearing clays and lithium brines. We are conducting laboratory experiments to measure lithium partitioning between clays and brines. Experimental results will be compared with real-world data to learn whether this model may be used as an exploration tool for predicting...
Sagebrush Mineral Resource Assessment
The USGS Mineral Resources Program completed a comprehensive assessment and inventory of potential mineral resources covering approximately10 million acres of federal and adjacent lands in Oregon, Idaho, Nevada, Utah, Wyoming and Montana.
Magmatic-Tectonic History and Component Sources of Major Precious Metal Deposits in the Southern Walker Lane
We conducted linked investigations to address the magmatic-hydrothermal evolution, post-mineralization structural histories, and sources of host rocks and hydrothermal mineral components of three significant, subduction-related, Au-Ag districts in the Walker Lane structural zone in the western Great Basin.
Alaska Critical Minerals Cooperative
The project developed means to use several large legacy digital databases together in GIS to identify areas with mineral resource potential for critical minerals in Alaska.
Global Mineral Resource Assessments
In response to the growing demand for information on the global mineral-resource base, the U.S. Geological Survey (USGS) completed assessments for undiscovered resources of porphyry and sediment-hosted copper, platinum-group elements, and potash.
Headwaters Province - Idaho and Montana: Earth Science Studies in Support of Public Policy Development and Land Stewardship
The Headwaters Province project provided geoscience data and interpretations to the Federal Land Management Agencies (FLMA) that were basic to sound policy and land-stewardship practices.
