Scientific study of the formation, location, and use of marketable geologic materials including fuels, metals, minerals, and water.
In-Place Oil Shale Resources Underlying Federal Lands in the Piceance Basin, Western Colorado [ More info] We estimated an in-place oil shale resource of 1.07 trillion barrels under Federal mineral rights, or 70 percent of the total oil shale in place, in this area.
Lead-Soft and easy to cast [ More info] Explains how we use lead, where it comes from, and how we might ensure that we have adequate supplies of this mineral commodity in the future.
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.
Lithium: for harnessing renewable energy [ More info] Explains how this element is used, where we get it, and prospects for future supply and demand.
Manganese: it turns iron into steel (and does so much more) [ More info] Explains how we use this metal, where we get it, and describes the current trends in supply and demand.
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.
Mineral commodity statistics and information [ More info] Database of mineral and material commodities with descriptions, contacts, and historical and current statistics of worldwide supply, demand, production and trade in Mineral Commodity Studies, Minerals Yearbooks, and special publications.
Mineral deposit models [ More info] Publications by the USGS on mineral deposit models converted to digital files that can be downloaded. Some are *.pdf files requiring Adobe Acrobat Reader to view and download text
Mineral Resources Data System (MRDS) [ More info] MRDS is a worldwide database of metallic and industrial mineral sites. Links to portions of the database that are available online.
