Mineral Information Layer for Oregon-Release 2 (MILO-Release 2) is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines. Understand that recreation in or around inactive mine sites is extremely dangerous, and can result in serious injury or death. Stay out and stay alive!
Mineral Information Layer for Oregon-Release 3 (MILO-Release 3) is a geospatial database that stores and manages information regarding Oregon's mineral occurrences, prospects, and mines.
This data set consists of records for over 900 mineral facilities in Latin America and Canada. The mineral facilities include mines, plants, smelters, or refineries of aluminum, cement, coal, copper, diamond, gold, iron and steel, nickel, platinum-group metals, salt, and silver, among others. Records include attributes such as commodity, country, location, company name, facility type and capacity if applicable, and generalized coordinates. The data were compiled from multiple sources, including the 2003 and 2004 USGS Minerals Yearbooks (Latin America and Candada volume), data to be published in the 2005 Minerals Yearbook Latin America and Canada Volume, minerals statistics and information from the USGS minerals...
X-Ray powder diffraction and thin section analyses indicate that marginal lacustrine mudstones of the Green River Formation in the south-central Uinta basin, Utah, contain abundant analcime. The analcime has a low Si/A1 ratio (<2.31) and occurs as very fine grained disseminated crystals and, to a lesser extent, as coarser-grained pore-filling cement. Analcime-rich mudstones and associated sandstones, siltstones, and carbonates lack volcanic detritus and zeolites other than analcime, thus making it diflicult to support the concept that the analcime formed from precursor zeolites derived from volcanic glass altered in saline, alkaline-lake water. Abundant dolomite, syneresis cracks, and the absence of freshwater pelecypods...

This dataset consists of records for over 1,500 mineral facilities in Africa and the Middle East. The mineral facilities include mines, plants, mills , or refineries of aluminum, cement, coal, copper, diamond, gold, iron and steel, nickel, platinum-group metals, salt, and silver, among others. Records include attributes such as commodity, country, site, company name, plant capacity if applicable, and generalized coordinates. The data were compiled from multiple sources, including the 2004 USGS Minerals Yearbook (Africa and Middle East volume), minerals statistics and information from the USGS minerals information Web site (http://minerals.usgs.gov/minerals/), and data collected by USGS minerals information country...
From the US Bureau of Mines map publication, "Availability of Federally Owned Minerals for Exploration and Development in the Western United States". The Bureau of Mines inventoried Federal mineral land in Wyoming and assessed the availability of this land for mineral exploration and development as affected by legal status and agency management practices. To illustrate the impact that various Federal land use decisions have on the mineral industry, the USBM also identified and ranked known mineral deposit areas (KMDAs)-i.e., areas having past or present mineral production and /or known mineral resources- and compared these areas spatially with availability of Federal mineral lands. Most Federal minerals, except...
