Mineral Resources Research

This project incorporates new geophysical technologies developed at the Tucson office of the Geology, Minerals, Energy, and Geophysics Science Center over the last 20 years for assessing mineral deposits concealed by basin sediments. These technologies include: textural classification of magnetic and magnetotelluric data and methods to characterize bedrock/basement lithologies, improved lineament...

The Macro and Micro Analytical Methods Development Project (MMAMD) provides access to the expertise of highly experienced research scientists and state of the art analytical instrumentation to develop new and unique analytical capabilities to solve complex problems beyond routine analysis.

Project objectives are to develop a modern probabilistic quantitative mineral resource assessment of Puerto Rico, U.S. Virgin Islands and adjacent geologically similar areas that examines the potential for minerals-based economic development and trade within the region.

The Development of Assessment Techniques and Analysis Project (DATAPII) objective is to modernize the application and development of USGS mineral resource and integrated multiresource assessment methodologies and capacity that are applicable at a variety of spatial and temporal scales, and national and international in scope.

Scientific research can make our resource assessments of critical minerals more effective. This project focuses on the Stillwater Complex, Montana, which has rocks enriched in platinum-group elements (PGE), chromium, cobalt, and nickel. Project objectives are to update databases, evaluate new mapping techniques, document new styles of mineralization, and document and support research on the...

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...

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.

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.

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.
