Radioactive mineral deposit locations were compiled on maps and lists, as well as production data/deposit summaries, in the CGS report: Nelson-Moore, J.L., Collins, D.B., and Hornbaker, A.L., 1978, Radioactive Mineral Occurrences of Colorado, Colorado Geological Survey Bulletin 40, 1,054 p. This comprehensive report contains 12 map plates that record the location of radioactive minerals, including past mined deposits, throughout Colorado. Also, the report contains compilations of production (if available), deposit type, mineral, and other data associated with each location. Most of the records are associated with uranium/vanadium deposits but also include deposits containing REEs and other minerals.
Boxes and maps of uranium exploration data were donated to the CGS several years ago referred to as the “Tallahassee Creek data.” This exploration data set focuses on the Hansen/Taylor, Picnic Tree, and High Park uranium deposits in the Tallahassee Creek mining area. These uranium deposits, a critical mineral as defined by Fortier and others (2018), occur in the Eocene Echo Park Alluvium and Oligocene Tallahassee Creek Conglomerate. Between 1957 and 1972, 95,400 tons of ore averaging 0.25% triuranium octoxide (U3O8) were mined in this area mostly from the Tallahassee Creek Conglomerate (Chenoweth, 1980). Exploration companies report Hansen/Taylor deposit resources of 29,730,000 tons grading at 0.063% U3O8 containing...
Digital files of basement structure in Colorado, including structure contours on top of Precambrian basement rock, selected wells drilled to Precambrian and Lower Paleozoic rocks, sedimentary basins, major oil and gas fields, Precambrian and Upper Cretaceous to Tertiary volcanic and intrusive rock outcrops. Major sedimentary basins and arches, as well as Precambrian mountain ranges and volcanic fields are included. Also included are 73 gas fields and 129 oil fields.
The data comprising this GIS and data download, digitized in 2020, is a partial compilation of the 1978 CGS publication Bulletin 40 – Radioactive Mineral Occurrences of Colorado (and Bibliography). Funding for this digitization project was from a U.S. Geological Survey National Geological and Geophysical Data Preservation Program (NGGDPP) grant with matching funds provided by the CGS. This two-part report provides an essentially complete listing of radioactive occurrences in Colorado, with a comprehensive bibliography and bibliographic cross-indexes. Part 1 lists approximately 3000 known radioactive occurrences with their locations and brief accounts of the geology, mineralogy, radioactivity, host rock, production...
Geologic, geologic hazard, and geotechnical reports submitted by county and municipal planners and school districts to the Colorado Geological Survey for review as part of land development applications.
GIS files for the 1:150,000-scale Geologic Map of Gunnison County included in Colorado Geological Survey RS-37 Geology and Mineral Resources of Gunnison County, Colorado.
GIS data collected from map plates within Colorado Geological Survey MS -17 Inventory of Nonmetallic Mining and Processing Operations in Colorado. The GIS dataset includes full metadata, the new shapefiles, and a layer file with symbology for ArcGIS. Also included is a 2022 Excel spreadsheet of all entries. The original report includes seventeen plates and text of locations of pits, quarries, and industrial minerals operations and processing plants of nonmetallic mining in Colorado. Covers: Vernal, Grand Junction, Moab, Cortez, Craig, Leadville, Montrose, Durango, Greeley, Denver, Pueblo, Trinidad, Sterling, Limon, Lamar, La Junta, Front Range Corridor and Southwest Pueblo.
Exploration materials donated to the Colorado Geological Survey from a commercial uranium exploration project after the commercial project was abandoned, and including raw data, partially interpreted data and interpreted data, and interim reports, of value not only for uranium exploration but also for mapping and understanding the shallow sedimentary and geochemical evolution of the area.
