From the site: "Major geologic units in the West Virginia region including metamorphic provinces, major faults, calderas, impact structures, and the limits of continental glaciation. The data depict the geology of the bedrock that lies at or near the land surface, but not the distribution of surficial materials such as soils, alluvium, and glacial deposits. Generalized geology shapefiles were downloaded from the National Atlas of the United States web site and clipped to an extent covering -76 to -84 degrees west longitude, 35 degrees 30 minutes to 42 degrees north latitude using a shape file that is included in the zip archive. Published April 2002. The data are generalized from a compilation prepared for use in the Geologic Map of North America, to be published in hard copy by the Geological Society of America and released as a digital file by the U.S. Geological Survey."
This submission includes the following: - Field Characteristics: Describes the geological and production field characteristics of sampling sites - Geochemistry of Produced Fluids Idaho-Nevada-New Mexico-Oregon-Utah: Summarizes the all the analytical results for aqueous samples collected from geothermal production wells, hydrocarbon production wells, and hot springs. - Geochemistry of Reservoir Rocks & Calcite Scales Nevada-Utah: Analytical results of trace element analyses of reservoir drill cuttings from Beowawe, Dixie Valley, Roosevelt Hot Springs, Uinta Basin, and Paradox Basin (Aneth field); also includes analyses of Dixie Valley calcite scales and rocks in the Sevier Thermal Belt, Utah. - Lithology and mineralogy of drill cuttings from Beowawe, Dixie Valley and Roosevelt Hot Springs: Lithological and mineralogical characterization of drill cuttings from Beowawe, Dixie Valley and Roosevelt Hot Springs - Geological Settings of Critical Element Mineral Deposits: Brief summary and references regarding the geological settings of critical element mineral deposits
This report documents the results of investigations dealing with the concentrations and availabilities of strategic, critical and valuable materials (SCVM) in produced waters from geothermal and hydrocarbon reservoirs (50-250 degrees C) in Idaho, Nevada, New Mexico, Oregon, and Utah. Analytical results were obtained for water samples from 47 production wells in 12 geothermal fields. Results were also obtained for samples from 25 oil/gas production wells in the Uinta and Paradox Basins and Covenant oil field, from 14 groundwater wells in the Tularosa play fairway (New Mexico), and from 20 groundwater wells and hot springs in the Sevier Thermal Belt (southwestern Utah). Please refer to GDR Submission 1126 (linked below) which houses the data summarized in the final report.
