Spatial databases for the geology of the Northern Rocky Mountains - Idaho, Montana, and Washington

The spatial databases represent the original content of 43 published geologic maps, provide normalized map unit descriptions, and provide additional information and interpretation not in the original reports.

Spatial digital database for the tectonic map of southeast Arizona

Geologic map GIS which represents the original content of the published geologic map and which can be queried in many ways to produce a variety of geologic maps and derivative products.

Stratabound copper-silver deposits of the Mesoproterozoic Revett Formation, Montana and Idaho with a section on databases and spatial-data files for the geology and mineral deposits of the Revett Formation

The sedimentary carbonate-hosted giant Bayan Obo REE-Fe-Nb ore deposit of inner Mongolia, China: A cornerstone example for giant polymetallic ore deposits of hydrothermal origin

Detailed geological and geochemical studies of this large deposit provided evidence for the origin and characteristics favorable for its formation and parameters necessary for defining giant polymetallic deposits of hydrothermal origin.

U.S. mineral dependence—Statistical compilation of U.S. and world mineral production, consumption, and trade, 1990–2010

The report provides insight into the dependence of the United States on foreign supply to meet the country’s mineral needs. This overview highlights the importance of understanding what is happening at each point along the supply chain.
