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.]

Concentrations of mercury and other metals in black bass (Micropterus spp.) from Whiskeytown Lake, Shasta County, California, 2005 [ More info] Historical gold mining has left this area susceptible to mercury contamination. Elevated concentrations of mercury in the fish are well documented here.
Copper - A Metal for the Ages [ More info] Sources, uses, and patterns of consumption of copper worldwide
Estimate of undiscovered copper resources of the world, 2013 [ More info] We estimated a mean of 3,500 million metric tons (Mt) of undiscovered copper among 225 tracts around the world using a geology-based assessment methodology.
In-place oil shale resources of the Mahogany zone sorted by grade, overburden thickness and stripping ratio, Green River Formation, Piceance Basin, Colorado and Uinta Basin, Utah [ More info] Refinement of previous resource estimate taking into account the characteristics and quality of oil shale as well as the amount of overburden throughout this area.
Map of assessed tight-gas resources in the United States [ More info] Shows where there are potential commercial sources of natural gas trapped in formations with very low permeability to gas (not necessarily shale units). Hydraulic fracturing might be needed in order to exploit these resources.
Nahcolite Resources in the Green River Formation, Piceance Basin, Northwestern Colorado [ More info] Resource assessment of nahcolite, a mineral with a variety of industrial uses, which occurs with oil shale and is affected by the processes used to recover hydrocarbons from the rock.
National Geologic Map Database Catalog [ More info] Search tool for locating print and online U.S. geologic maps by area, title, author, etc.
Potential for technically recoverable unconventional gas and oil resources in the Polish-Ukrainian Foredeep, Poland [ More info] Using a performance-based geological assessment methodology, we estimated mean volumes of 1,345 billion cubic feet of potentially technically recoverable gas and 168 million barrels of technically recoverable oil and natural gas liquids here.
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.
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.
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.
