Summary of the diamond resource potential and production capacity assessment of Guinea [ More info] Describes organizational process and field study used to estimate production capacity (mostly by artisanal miners) in the parts of the country likely to contain diamonds. We estimate a production capacity of 600,000 carats per year.
Summary of the reconnaissance investigation of the diamond resource potential and production capacity of Côte d'Ivoire [ More info] Study integrating archival reports and maps, satellite imagery, and terrain modeling to estimate resource reserves of 11,200,000 carats in two regions of the country.
The future of rare earth elements--will these high-tech industry elements continue in short supply? [ More info] Presentation describing uses of rare earth elements, why they are important, where they occur and are produced, and aspects of the economics of production and consumption with emphasis on sites that might be developed for production.
The principal rare earth elements deposits of the United States-A summary of domestic deposits and a global perspective [ More info] Explains the geologic setting in which these deposits are found, with information about production and the processes used to extract these valuable mineral resources.
Tintina gold province study, Alaska and Yukon Territory, 2002-2007 [ More info] New discoveries and modernized extraction methods prompted renewed interest in gold deposits in this part of central Alaska, prompting a variety of studies described here.
USGS National Map of Surficial Mineralogy [ More info] Maps of exposed surface mineral groups derived from automated spectral analysis of satellite and airborne imaging systems; these data suggest areas that may contain mineral deposits of various types.
Understanding processes affecting mineral deposits in humid environments [ More info] Contaminants from mines move more easily from ore materials and mine waste piles to surrounding estuaries and living organisms when water moves through the mine site. Geochemical results shown here will help people mitigate the negative effects.
Undiscovered Gas Resources in the Alum Shale, Denmark, 2013 [ More info] We estimated a mean undiscovered volume of 6.9 trillion cubic feet of natural gas in this geologic unit using a geology-based assessment methodology.
Water quality studied in areas of unconventional oil and gas development, including areas where hydraulic fracturing techniques are used, in the United States [ More info] Maps showing number of water quality samples in areas underlain by unconventional oil and gas resources, broken out by surface water and groundwater.
