Isotope and Chemical Methods for Mineral and Geoenvironmental Assessments and Support of USGS Science Strategy

This Project integrates several geochemical tools—stable isotope geochemistry, noble gas geochemistry, active gas geochemistry, single fluid inclusion chemistry, and fluid inclusion solute chemistry—in studies of the processes that form mineral deposits and the processes that disrupt them during mining or natural weathering. Research is directed toward fundamental scientific questions or, in...

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....

GIS and Information Management - GGGSC

We support the geospatial component of Mineral Resources Program research and provide public access to research results and geospatial information. We facilitate all aspects of the data life cycle, including the publication and archiving of geospatial information and products. We also develop and steward national-scale data layers considered foundational to the Mineral Resources Program as...

Geochemical Signatures and Environmental Impacts of Ore and Trace Mineralization in the Southern Midcontinent

The overall project objective is a comprehensive analysis of the natural and anthropogenic consequences of extensive ore and trace mineralization in the southern midcontinent of the U.S. with a focus on Missouri. This will be conducted at two scales: 1) landscape and 2) process-level.

1) Landscape scale using geospatial and machine learning techniques to combine multiple geochemical and...

Systems Approach to Critical Minerals Inventory, Research, and Assessment

This project supports the Earth Mapping Resources Initiative (EarthMRI) by developing a mineral systems approach for defining focus areas. This project is investigating domestic sources of critical minerals in three sequential stages: inventory, research, and assessment.

1) Inventory the abundance of critical minerals in ore, minerals, and processed materials from major deposits in each...

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 ...

Magmatic-Tectonic History and Component Sources of Major Precious Metal Deposits in the Tonopah, Goldfield, and Comstock Lode Districts, NV

Project objectives are refinement of stratigraphy, structure, and magmatic-hydrothermal evolution of the Tonopah, Goldfield, and Comstock Lode districts, and determination of the sources of hydrothermal mineral components. Results are expected to  include refined geologic and tectonic maps of important districts in the Walker Lane, reduced uncertainty in sources of elements in ore deposits,...
