Mineral deposit areas
Areas where masses of naturally occurring mineral material are found, e.g. metal ores or nonmetallic minerals. [Adapted from Glossary of Geology, 4th ed.]

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.
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.
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.
A methodology for conducting national-scale alluvial diamond resource potential and production capacity assessments, with a focus on artisanal mining [ More info] Geologic evidence, combined with geographical data and analyized through a geographic information system allows us to compare production statistics with likely resource estimates.
An estimate of undiscovered conventional oil and gas resources of the world, 2012 [ More info] Using a geology-based assessment methodology, we estimated means of 565 billion barrels of conventional oil and 5,606 trillion cubic feet of undiscovered conventional natural gas in 171 priority geologic provinces of the world, exclusive of the U.S.
An evaluation of the science needs to inform decisions on Outer Continental Shelf energy development in the Chukchi and Beaufort Seas, Alaska [ More info] We need refined regional understanding of climate change, effective oil-spill risk assessment, preparedness, and response, an analysis of cumulative effects (natural and human), better geospatial data for the area, in an integrated approach.
Assessment of Gas Hydrate Resources on the North Slope, Alaska, 2008 [ More info] We estimate that there are about 85 trillion cubic feet (TCF) of undiscovered, technically recoverable gas resources within gas hydrates in northern Alaska.
Assessment of in-place oil shale resources of the Green River Formation, Greater Green River Basin in Wyoming, Colorado, and Utah [ More info] Using the Fischer assay measure of oil yield, we estimated a total of 1.44 trillion barrels of oil in three assessed units. There is currently no economic method to recover oil from this geologic unit.
Assessment of Paleozoic shale gas resources in the Sichuan Basin of China, 2015 [ More info] We estimated a mean of 23.9 trillion cubic feet of technically recoverable shale gas resources in Paleozoic formations in this area using a geology-based assessment methodology.
Assessment of potential additions to conventional oil and gas resources of the world (outside the United States) from reserve growth, 2012 [ More info] We used mathematical models to estimate the likely increases in the estimates of the amount of oil and gas technically recoverable from existing known large fields outside the US.
