Multi-scale Screening Techniques for Legacy Mine Land (LML) Sites Using Data Mining and Site-specific Studies in the Western U.S.

The main goal of this project is to provide a science-based approach for screening legacy mine land (LML) sites for remediation and identifying watersheds where relatively low-cost restoration efforts may yield substantial improvements to stream water quality. We are combing analysis of multiple existing regional data coverages with focused field studies to develop a protocol that land...

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...

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.

Geophysical and Geochemical Approaches to Evaluating Rare Earth Element (REE) Potential in the Southeastern U.S.

Rare-earth elements (REE) are an essential component of numerous advanced technology applications including high efficiency batteries, emerging energy technologies, and key defense systems. The goal of this study was to assist in the evaluation of the distribution of rare earth element deposits in the southeastern U.S., with a focus on sediment-hosted resources.
