Life Cycles of Byproduct Critical Minerals
Project objectives are to 1) assess the overall life cycle of selected byproduct critical elements tellurium (Te), indium (In), gallium (Ga), and germanium (Ge), 2) perform an assessment of critical element resources and examine the processes and conditions controlling the concentration of byproduct critical elements by deposit type, and 3) improve understanding of the surficial geochemistry...
New Applications of Hyperspectral Imaging to Delineate Critical Minerals Concentrated in Regolith and Mine Waste Materials
Our project will develop new and innovative spectral methods and remote sensing tools for understanding how critical minerals are concentrated by weathering, regolith/soil formation, mining, runoff and ore processing. These tools will help us to use mineralogy derived from spectral measurements (lab, field, and remote sensing) to help delineate vectors towards recoverable resources and to...
Geoenvironmental Health Models of Mineral Deposits
Our objectives are to: 1) complete bioaccessibility testing on monominerallic samples of important ore and gangue minerals for selected elements of toxicological concern, and 2) create a compendium of mineral deposit geoenvironmental health models.
Application of the National-Scale Soil Geochemical and Mineralogical Data for the Conterminous U.S.
Project goals were to produce interpretive products based on the exising national-scale geochoemical and mineralogical data and maps for soils of the conterminous U.S.
Backgrounds and Baselines
This project developed a geochemical information base through studies ranging in scale from site-specific to regional and national.
USGS Abandoned Mine Lands Initiative
The U.S. Geological Survey (USGS) conducted an Abandoned Mine Lands (AML) Initiative during the fiscal years 1997 through 2001 to provide technical assistance in support of Federal Land Management Agency (FLMA) actions to remediate contamination associated with abandoned hard rock mining activities. This initiative was part of a larger strategy by the U.S. Department of the Interior and the U....
