Integrated Hyperspectral, Geophysical and Geochemical Studies of Yellowstone National Park Hydrothermal Systems

We are researching the subsurface groundwater flow systems in Yellowstone and the relation of these systems to understanding the regional movement of water in a volcanic center. New geophysical data will be integrated with existing data sets from hyperspectral data from Yellowstone's thermal areas and thermal water geochemistry to help define regionally extensive mineral assemblages, the evolution...

Geophysics of the Midcontinent Rift Region

The Midcontinent Rift system and surrounding Precambrian rocks are known to host highly significant mineral resources. Our project objectives are to increase understanding of this system through the integration of new and legacy geophysical data with geochemical and borehole data, map the lithology and structure of PreCambrian rocks, and develop an integrated 3D geologic model of the region.

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...

Critical Mineral Resources in Heavy Mineral Sands of the U.S. Atlantic Coastal Plain

In many parts of the southeastern U.S., dark-colored sands can be seen at beaches or beneath soil. These sands contain titanium, zirconium, and rare earth elements, which are considered critical mineral resources. Such sands are present in areas from the coast to a hundred miles or more inland beneath soil within the Atlantic Coastal Plain Province. In some locales they are concentrated enough to...
