Continental Scale Geophysics — Integrated Approaches to Delineate Prospective Environments for Critical Metals
Regional geophysical data that are available over continental scales such as magnetic, gravity, and magnetotelluric data can provide a foundation towards identifying and understanding the footprints and deep plumbing systems underlying these important ore systems. Our project will use continental-scale geophysical data to map the locations of deep crustal and mantle structures that may act as...
Heavy-Mineral Sand Resources in the Southeastern U.S.
We are assessing the extent of industrial mineral resources hosted by heavy-mineral sands in the coastal plain of the southeastern United States. “Heavy-mineral sands" (HMS) is a term commonly used in industry and geologic literature to describe layered sediments deposited in coastal environments that contain dense (“heavy") minerals of economic value. The heavy minerals extracted from these...
Sagebrush Mineral Resource Assessment
The USGS Mineral Resources Program completed a comprehensive assessment and inventory of potential mineral resources covering approximately10 million acres of federal and adjacent lands in Oregon, Idaho, Nevada, Utah, Wyoming and Montana.
