USMIN Mineral Deposit Database
Our objective is to develop a national-scale, geospatial database that is the authoritative source of the most important mines, mineral deposits, and mineral districts of the United States.
From Outcrop to Ions: development and application of in-situ isotope ratio measurements to solve geologic problems
Project objectives are to (1) develop innovative analytical techniques for isotope geochemistry and U-Pb geochronology using laser ablation inductively coupled plasma mass spectrometry (LA-ICP-MS), and (2) apply these techniques to collaborative research projects of high priority to the Mineral Resources Program, including studies related to the formation of "critical mineral" deposits, and...
Geophysics of Precambrian Terranes, Upper Midwest and Rocky Mountains
The project objective is to provide follow-up geophysical ground data acquisition and interpretation for areas involving Precambrian geologic settings in the Upper Midwest and Rocky Mountains. The project is designed fill gaps and to complement the high-quality aeromagnetic acquired during the USGS Earth Mapping Resources Initiative (Earth MRI).
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.
Geophysical Mapping of Geologic Systems Host to Critical Mineral Deposits, Southern Midcontinent, US
The objective of this project is to use high-resolution state-of-the-art airborne and regional ground geophysical methods to map an underexplored region of the southern Midcontinent that is important to economic and critical mineral deposits.
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 well as...
Sediment-Hosted Copper Deposits in the Lake Superior Portion of the Midcontinent Rift System
This project is focused on the sediment-hosted copper deposits of the Midcontinent Rift, with three main objectives: 1) describe the ore mineralogy and geochemistry of the White Pine and Copperwood deposits, 2) evaluate whether hydrothermal alteration in footwall rocks can be used as a vector towards ore, and 3) provide a careful scoping study to evaluate whether unconventional platinum-group...
Unconventional Stratabound Critical Mineral Deposits of the Midcontinent: Linkages Between Mineralization in Marine Epicontinental Sedimentary Basin Systems
This project will evaluate and characterize the critical mineral potential of midcontinent stratabound "Bathtub Rim" deposits for rare earth elements, cobalt, lithium, and associated critical mineral prospectivity and to develop and test new ore genesis models.
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 geologic...
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 system...
Iron Oxide-Copper-Cobalt-Gold-Rare Earth Element Deposits of Southeast Missouri—From the Ore Deposit Scale to a Global Deposit Model
The project main objectives are to: 1) geologically, characterize the setting and origin of the iron-copper-cobalt-gold-rare earth element deposits, and advance the knowledge of rare earth element and Co potential within iron oxide-copper-gold (IOCG) deposits of southeast Missouri, and 2) geophysically delineate and characterize the subsurface Precambrian geology using existing ground and new...
