Geochemical survey of TRI-state mining areas, missouri, kansas, and oklahomaproject period: 12-1-2024 to 11-30-2027PURPOSE - the missouri geological survey (MGS), kansas geological survey (KGS), and…

This Cooperative Agreement, awarded by the U.S. Geological Survey (USGS) under the Earth Mapping Resources Initiative (CFDA 15.073), provides $549,995 to conduct a regional geochemical survey of the Mississippi Valley-Type Tri-State mining district located in Missouri, Kansas, and Oklahoma. The Missouri Geological Survey (MGS), Kansas Geological Survey (KGS), and Oklahoma Geological Survey (OGS) will collaborate to collect up to 500 geological samples, analyze them for critical mineral content, and develop a comprehensive geochemical database and map products. The project aims to improve understanding of critical mineral behavior and mineralization within the district, which can inform future exploration, environmental management, and infrastructure planning efforts. The 3-year project period runs from Dec 1, 2024 to Nov 30, 2027, with the three state geological surveys serving as sub-recipients to conduct sample collection, analysis, and reporting activities within their respective state boundaries.

Geochemical survey of TRI-state mining areas, missouri, kansas, and oklahomaproject period: 12-1-2024 to 11-30-2027PURPOSE - the missouri geological survey (MGS), kansas geological survey (KGS), and oklahomageological survey (OGS) will do a systematic geochemical survey of the mississippi valley-type (MVT)TRI-state district, located in southwestern missouri, southeastern kansas, and northeastern oklahoma. The survey will document ZN, GA, GE, and in occurrence, other critical mineral potential, andpetrophysical, alteration, and host rock data. IT will provide insights into mineral concentration anddistribution, assist ORE potential appraisal, and support frameworks for critical minerals in MVT systems.GIS-based maps will advance critical mineral system and MVT model development. The area has noknown tribal impacts in missouri or kansas. The oklahoma portion contains tribal lands OGS willprovide guidance in these areas.activities - MGS, in conjunction with KGS and OGS, will define sampling methods, coordinate andmonitor sample collection (including pxrf and USGS reference materials), and consolidate samplesubmission to the USGS. Evaluation methods will be developed cooperatively. Samples will includeoutcrops, historic mines, archived hand samples, cores, and cuttings all samples will have pxrf datacollected. Up to 500 samples will be submitted to the USGS for analysis. MGS will develop ageochemical database using USGS data provisions. Each state will conduct in-state sample collection, description, pxrf evaluation, and entry into databases.deliverables and outcomes - MGS will remit required deliverables with collaboration from KGS andogs. Geospatial data and maps will be in gems format, and published jointly by MGS, KGS, and OGS.data also will be published on state survey websites, rescicoll, or both. Each agency may pursueadditional publications with inter-agency cooperation. Deliverables will be reconnaissance geochemicaldata, comprising: a consolidated sample set with preliminary pxrf semiquantitative analysis data, samplelocations, and stratigraphic descriptions, submitted to the USGS for geochemical analysis. A comprehensive summary report, led and published by MGS in cooperation with KGS andogs, with appropriate peer review and public release. MGS publication of a jointly developed final geochemical database and geospatial map productsthat present a regional assessment of geochemical results from all three states.outcomes include improved understanding of critical mineral behavior in the district. Sampledescriptions, including those indicative of metal transport and deposition, will clarify mineralization, hostrock, and structure relationships. District-wide samples will provide an extensive data set for futurestudies. Integration of regional stratigraphy, spatial geochemical data, and existing models will improveknowledge of the MVT system within the overall framework. The data will likely suggest additionalinvestigations. Data also can assist future environmental responses and crushed stone production.intended beneficiaries - beneficiaries include geoscientists developing MVT mineralization models forcritical mineral and geologic frameworks. New physical samples will provide a broad data set for futuregeoscience studies. The data can assist in avoidance of mineralized areas for crushed stone producers andprovide data for environmental scientists, including in mine waters and mine waste in past mined areas.geoscientists, engineers, and civic officials can use field locations of mines to address collapse potential.subrecipient activities - KGS and OGS will provide input for sampling methods, collect samples anddata (including pxrf analyses) (activities), and documentation and input for all reports, including textfor sections concerning their states (deliverables and outcomes). Each state will enter appropriate sampleand pxrf data into all databases.
