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...

Advancements in Geochemistry and Geomicrobiology of Energy Resources (AGGER)

The AGGER project seeks to advance the understanding of factors that indicate and control the sources, generation, composition, stimulation, accumulation, movement, and production potential of petroleum, nuclear fuel resources (e.g., uranium and thorium), and their byproducts as well as the potential for resource recovery from wastes generated during extraction.

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.

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 managers...

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.
