USMIN Mineral Deposit Database
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.
GIS Prospectivity Analysis for Critical Minerals in Ore-Forming Systems in Alaska
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.
Multidisciplinary Investigations of REE Mineralization at Mountain Pass and in the Southeast Mojave Desert, California
In this time of increased focus on renewable energy technologies, rare earth elements (REEs) are of critical importance. For example, neodymium (Nd) is a REE used in the generator and motor magnets of wind turbines and electric vehicles. Reliance on REE imports puts the U.S. at high risk for supply disruption. The project will integrate geology, geophysics, petrology, geochronology, and economic...
A Shallow to Deep View Inside the Hydrothermally Altered and Mineralized Silverton Caldera Complex: New Geologic Insights Gained From Modern Geophysical Interpretations
The Silverton caldera complex in southwest Colorado hosts base and precious metals that have been mined since the late 1800s. Extensive mine workings, excellent bedrock exposures, and deeply incised drainages make this area a natural laboratory ideally suited for furthering our understanding of the mineral systems in a volcanic environment. In addition, state-of-the-art geophysical data processing...
Mineral Resource Online Data Catalog
This project makes the digital spatial data produced by the Mineral Resources Program available via a web portal so that users can easily access spatial data for solving scientific and technical problems: the Mineral Resources Online Spatial Data site.
Evaluation of Critical Elements in Carbonatites
The project objective is to determine the processes responsible for critical element enrichment in carbonatites and to enhance our ability to identify and assess economic deposits. This project will work at various scales to meet this objective and will primarily focus on deposits within the US or our Critical Minerals Mapping Initiative collaborative Nations Canada and Australia.
Isotope and Chemical Methods for Mineral and Geoenvironmental Assessments and Support of USGS Science Strategy
This Project integrates several geochemical tools—stable isotope geochemistry, noble gas geochemistry, active gas geochemistry, single fluid inclusion chemistry, and fluid inclusion solute chemistry—in studies of the processes that form mineral deposits and the processes that disrupt them during mining or natural weathering. Research is directed toward fundamental scientific questions or, in...
Critical Mineral Recovery Potential from Tailings and Other Mine Waste Streams
The primary objectives of this one-year scoping project are to determine the feasibility of extracting byproduct mineral commodities, such as critical minerals, from mine tailings. We plan to analyze the existing data and reports from an active mine site on the composition of their mill tailings pile, and collect preliminary reconnaissance samples to identify appropriate analytical techniques that...
Research Mineralogy - X-ray Diffraction Lab
The primary goal of this project is to ensure the availability of state-of-the-art mineralogical analyses and, when needed, development of new analytical methods that can be applied to topical studies in Energy and Minerals Mission Area, as well as the other mission areas. The project includes mineralogy by X-ray diffraction (XRD), qualitative and semi-quantitative x-ray fluorescence spectroscopy...
Lithium from Source to Sink: Genesis and Evolution of Li Brines and Clays
The purpose of this project is to trace the lithium (Li) geochemical cycle in the Great Basin, with an emphasis on the pathways that lead to the development of lithium clay and brine resources.
Mineral Resource Assessment Training
The USGS Mineral Resources Program conducts mineral resource assessments and is training USGS scientists in how to conduct these assessments for future work. As a practical exercise, the scientists will conduct an assessment for tungsten in the U.S.
Volcanic-related Beryllium Deposits of the US: Geologic Setting, Genesis, and the Potential for Post-Extraction Recovery of By-Product Critical Minerals
Project objectives are: 1) to fully establish a comprehensive and robust geologic and geochemical framework for the occurrence of volcanic-related beryllium (Be) deposits; 2) further our understanding of the fundamental ore processes that lead to formation of volcanogenic beryllium (Be)-boron (B)-lithium (Li)-phosphorus (P) group deposits, by investigating processes favorable for enhanced...
