Geophysical Studies on the Architecture of Large Igneous Systems Hosting Magmatic Ore Deposits
Platinum group elements, also known as PGEs, are a group of elements that have specific properties which make them useful for various applications in industry. One geologic setting that contains large concentrations of platinum group elements is layered mafic intrusions. This project will use new and preexisting geophysical datasets to characterize the internal structure of layered intrusions...
Geologic Mapping of the Lower Colorado River System
This is a comprehensive scientific investigation of the geologic history and framework of the lower Colorado River. We are using geologic mapping in combination with stratigraphic, geochronologic, and geophysical studies to develop a holistic understanding of the river’s origin, the structural history of the landscape through which it flows, and the stratigraphic and geomorphic consequences of the...
Geologic Mapping in the Southern Pacific Border and Sierras provinces, California
This project uses geologic and geophysical mapping to build an earth-science framework for scientific investigations that include assessments of critical resources, such as groundwater, and of hazards, such as those resulting from earthquakes, in California west of and including the Sierra Nevada and Cascade arc. Questions of particular interest include: What are the geometries, slip rates, and...
Platinum-Group Elements in Layered Intrusions Associated with the Midcontinent Rift
Platinum-group elements (PGE) are critical commodities. They are essential for the U.S. economy; however the U.S. imports about 90 percent of the platinum-group elements that we need to use. The project objective is to assess the Duluth Complex and related mafic-ultramafic intrusions in the 1.1 Ga Midcontinent Rift System in the Lake Superior region. Our current activities focus on a Keweenawan...
Critical commodity studies, Stillwater Complex, Montana and Duluth Complex, Minnesota
Scientific research can make our resource assessments of critical minerals more effective. This project focuses on the Stillwater Complex, Montana, which has rocks enriched in platinum-group elements (PGE), chromium, cobalt, and nickel. Project objectives are to update databases, evaluate new mapping techniques, document new styles of mineralization, and document and support research on the...
