Critical Minerals

This project continues work on large magmatic systems in the U.S., where critical mineral commodities important to clean energy technologies can be concentrated. Modeling of large mafic intrusion extents will continue, and new geophysical methods will be applied to improve understanding of magmatic systems.

The project objective is to develop and apply solution and in situ isotopic and trace element methods to emerging research opportunities to gain a better understanding of the processes controlling critical mineral deposits, metal mobility, and other geological inquiries.

The USGS, in combination with Geoscience Australia and the Geological Survey of Canada, formed the Critical Minerals Mapping Initiative (CMMI) in 2019 to combine expertise and collaboratively conduct research on critical mineral resources.

The Alaska Resource Data File (ARDF) site provides descriptions of mines, prospects, and mineral occurrences for individual U.S. Geological Survey 1:250,000-scale quadrangles in Alaska.

The Project objective is to facilitate the full potential of stable isotope (C,H,N,O,S), noble gas isotope (He, Ar, Ne, Ar, Kr, Xe), active gas geochemistry (CO2, H2S, SO2, CH4, HF, HCl, N2, H2, organics, light hydrocarbons), and solute geochemistry measurements of minerals and fluids (including single fluid inclusions) in multidisciplinary studies of fundamental processes that affect mineral...

This project supports the Earth Mapping Resources Initiative (EarthMRI) by developing a mineral systems approach for defining focus areas. This project is investigating domestic sources of critical minerals in three sequential stages: inventory, research, and assessment. 1) Inventory the abundance of critical minerals in ore, minerals, and processed materials from major deposits in each system...

We support the geospatial component of Mineral Resources Program research and provide public access to research results and geospatial information. We facilitate all aspects of the data life cycle, including the publication and archiving of geospatial information and products. We also develop and steward national-scale data layers considered foundational to the Mineral Resources Program as well as...

The National Geochemical Database project assembles, reformats, corrects, and archives historical data obtained from the geochemical analysis of millions of geologic samples collected for USGS studies. These data, representing hundreds of millions of dollars' worth of USGS research, are provided to USGS researchers; other Federal agencies; State Geological Surveys and Environmental Protection...

The project seeks to better understand the mineral systems of the Boulder batholith and surrounding region in Montana using new airborne geophysical data in conjunction with geologic mapping.

Our objective is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, and mineral districts of the United States.

Alaska is dominated by a history of tectonic events that foster mobilization and concentration of a wide variety of mineral commodities that are critical to the US economy and are vital to national defense, renewable-energy, and emerging electronics technologies.

The rare earth elements (REEs) are a group of metals with unique physical and chemical properties that are critical to a variety of technological applications. For example, neodymium (Nd) is a REE used to manufacture high strength, lightweight magnets that power electric motors at all scales, from cell phones to airplanes. Reliance on REE imports puts the U.S. at high risk for supply disruption...
