Mineral Resources On-Line Spatial Data
1998 Assessment of undiscovered deposits of gold, silver, copper, lead, and zinc in the United States Estimates of the tonnages and amounts of contained metal in undiscovered deposits, mineral deposit types.
Quantitative mineral resource assessment of copper, molybdenum, gold, and silver in undiscovered porphyry copper deposits in the Andes Mountains of South America Regional tracts of land where the geology is permissive for the occurrence of undiscovered porphyry copper deposits, with probabilistic estimates of undiscovered resources, along with tables of discovered deposits and prospects.
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.
Economic filters for evaluating porphyry copper deposit resource assessments using grade-tonnage deposit models, with examples from the U.S. Geological Survey global mineral resource assessment This paper reports on a methodology that is used with estimates of undiscovered copper resources to evaluate the likely contribution that the predicted resources will make to mineral supplies in the foreseeable future.
Geochemical analysis of soils and sediments, Coeur d'Alene drainage basin, Idaho: Sampling, analytical methods, and results Chemical composition of sediments and soils are of interest because of the potential for human and wildlife health impacts from high metal contents due to over 100 years of mining activity.
Local-area-enhanced, 2.5-meter resolution natural-color and color-infrared satellite-image mosaics of the Panjsher Valley mineral district in Afghanistan GeoTIFF rendition of locally enhanced ALOS image mosaics for this area known to contain emerald and silver-iron deposits.
Sediment-hosted zinc-lead deposits of the world - Database and grade and tonnage models This report provides information on sediment-hosted zinc-lead mineral deposits based on the geologic settings that are observed on regional geologic maps.
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.
