Mineral Resources Program

Regional Studies and Mineral Resources

Geologic, geophysical, and geochemical studies are used to evaluate the mineral endowment of strategic and critical minerals in selected regions of the United States.  Understanding the formation of major mineral deposits, which provide for society’s needed resources, can have broad impact on the economy and the environment.

Development and Validation of Hyperspectral Imager for Field and Lab Scanning

The Mineral Resources Program has advanced methods of imaging spectroscopy (hyperspectral remote sensing) that are now used routinely by the earth science and remote sensing communities for mineral mapping, soil quality mapping, hazard mitigation, and other terrestrial and planetary applications. The USGS is highly qualified to advance this technology based on its world class expertise in...

USGS High Resolution Spectral Library

The USGS Spectral Library contains reflectance spectra, including samples of minerals, rocks, soils, physically constructed as well as mathematically computed mixtures, plants, vegetation communities, microorganisms, and man-made materials. The samples and spectra collected were assembled for the purpose of using spectral features for the remote detection of these and similar materials. The...

Geologic Map of Alaska

In January 2016, the U.S. Geological Survey released the first ever digital geologic map of Alaska. This map reflects more than a century of work and provides a visual context for the abundant mineral and energy resources found throughout the state. The map also is available to use in three different formats: a professional GIS database, a public interactive version via a web browser, and an...

Western Alaska Range Metallogeny and Tectonics

There are many different types of mineral deposits present in the Western Alaska Range: plutonic gold, porphyry copper-gold (Pebble prospect), epithermal gold, tin-silver skarns, sedimentary barite, mafic hosted nickle-platinum-group elements, uranium-thorium rare earth elements, and even a diamond prospect.

Petrogenesis and REE Metallogenesis of 1.4 Ga Magmatism in the Conterminous U.S.

This project evaluated the petrology and metallogeny of rare earth element-mineralized 1.4 Ga intrusive systems at Mountain Pass and in the St. Francois Mountains relative to those of other, apparently, unmineralized 1.4 Ga intrusive systems in the conterminous U.S.

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.

Nonmetallic Industrial Mineral Resources of the U.S.

In 2012, this project initiated a multi-year effort to characterize domestic nonmetallic industrial mineral resources that are important for national infrastructure, agriculture, and energy development. Activities included (1) a national-scale compilation of production data, providing a snapshot of the nonmetallic industrial mineral deposits that were of significance through the 20th century...

Multidisciplinary Studies to Image and Characterize the Mineral Resource Potential of the Midcontinent Rift, USA

This multidisciplinary study seeks to image and characterize the mineral resource potential of the Midcontinent Rift System. Combining various geophysical methods with detailed mapping and geochemical analyses will help to define the geographic extent of the Rift and clarify its geologic makeup and configuration.

Alaska Geophysical Survey Interpretation

Available geophysical data for Alaska have not been fully exploited. Project objectives were to conduct systematic analysis of existing gravity, aeromagnetic and airborne electromagnetic data to map geologic trends, structural geologic and tectonic patterns, and identify key lithologies for direct integration with geologic framework and mineral potential studies.

MIneral Resources External Research Program

In 2004, the Mineral Resources Program introduced an External Research Program, which ran through 2014. This grant and/or cooperative agreement opportunity was available to universities, state agencies, industry, or other private sector organizations that had the ability to conduct research in topics that met the goals of the Mineral Resources Program.

Basement Tectonic Framework of the U.S.: Role of Cratonization of Juvenile Crust and Structural Modification in Forming Metallogenic Provinces

Project objectives were to publish a map of the nation's geologic basement. The map portrayed these pieces (domains) from the most ancient to recent, by the events that influenced their composition, starting with their origin.

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.
