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.]

Copper - A Metal for the Ages [ More info] Sources, uses, and patterns of consumption of copper worldwide
Development of industrial minerals in Colorado [ More info] Explains how industrial minerals are produced and overseen through governmental regulation, and describes the industrial mineral resources of central Colorado.
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 examined by grade in the major basins of the Green River Formation, Colorado, Utah, and Wyoming [ More info] We estimated a total of 4.285 trillion barrels of oil in-place in the oil shale of this area using a geology-based assessment methodology.
In-place oil shale resources in the saline-mineral and saline-leached intervals, Parachute Creek Member of the Green River Formation, Piceance Basin, Colorado [ More info] We estimated 920 and 352 billion barrels of oil are potentially recoverable from oil shale resources using oil-yield cutoffs of 15 and 25 gallons per ton, respectively.
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.
Limestone - A crucial and versatile industrial mineral commodity [ More info] Uses and availability of limestone and related commodities such as lime and portland cement. Hazards of limestone terranes due to erosion and sinkhole formation.
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.
Microbial production of natural gas from coal and organic-rich shale [ More info] Explains how natural gas can be formed by microorganisms from geological materials, and how we plan to assess the potential value of this process for improving energy resources.
