Mineral Resources On-Line Spatial Data
Aquatic assessment of the Ely Copper Mine Superfund site, Vershire, Vermont A wide variety of geochemical analyses show strong local impact on water quality in this area of historical copper mining.
Aqueous geochemical data from the analysis of stream-water samples collected in June and August 2008--Taylor Mountains 1:250,000- and Dillingham D-4 1:63,360-scale quadrangles, Alaska Measurements on 92 samples, including pH, conductivity, water temperature, major cation and anion concentrations, and trace-element concentrations.
Aqueous geochemical data from the analysis of stream-water samples collected in June and July 2006-Taylor Mountains 1:250,00-scale quadrangle, Alaska Analyses of 72 water samples include pH, conductivity, water temperature, major cation and anion concentrations, trace-element concentrations, and dissolved organic-carbon concentrations.
Chemical analyses of soils and other surficial materials of the conterminous US Geochemistry of soils and other regoliths collected and analyzed by Hans Shacklette and colleagues from 1958 until about 1976.
Descriptive models, grade-tonnage relations, and databases for the assessment of sediment-hosted copper deposits--with emphasis on deposits in the Central Africa Copperbelt, Democratic Republic of the Congo and Zambia This report describes compilation and evaluation results of data from the USGS global mineral assessment including new descriptive mineral-deposit and grade and tonnage models and spatial databases for deposits and occurrences, ore bodies and open pits.
Geochemical and stable isotopic data on barren and mineralized drill core in the Devonian Popovich Formation, Screamer sector of the Betze-Post gold deposit, northern Carlin trend, Nevada Detailed chemical and isotopic analysis of host and associated rocks within an area that is currently the largest producer of gold in the US. Part of a study of the hydrothermal activity leading to the formation of these gold deposits.
Geochemical data for core and bottom-sediment samples collected in 2007 from Grand Lake o' the Cherokees, northeast Oklahoma In this area of historical lead-zinc mining activity, studies such as this help to assess the possibility of human exposure to cadmium and lead through eating fish.
Geochemical data from groundwater at the proposed Dewey Burdock uranium in-situ recovery mine, Edgemont, South Dakota Groundwater geochemistry data from samples that were collected in June 2011 to better understand the hydrogeologic system in the area surrounding the proposed mine site.
Geochemical data from waters in Prospect Gulch, San Juan County, Colorado, that span pre- and post-Lark Mine remediation Water samples near this abandoned mine were analyzed for specific conductance, pH, temperature, and dissolved oxygen with handheld field meters, and metals were analyzed using inductively coupled plasma-mass spectrometry.
Geochemical results from stream-water and stream-sediment samples collected in Colorado and New Mexico Data from a study intended to explore how well the chemical analysis of water and sediment in an area reflects that of the rock from which the sediments are eroded and through which the water flows.
