Mineral Resources On-Line Spatial Data
Geochemical analyses of rock, sediment, soil, mineral, and heavy mineral concentrate samples in Alaska analyzed from 1962 through 2009, with best-value estimates.
Seventy-seven major components of the North American continent were delineated at a general scale (1:5,000,000); including the general composition, geological environment, and types of primary metals endowments that can be expected in each domain.
This report describes compilation and evaluation results of data from the USGS global mineral assessment including new descriptive mineral-deposit and grade and tonnage models and spatial databases for deposits and occurrences, ore bodies and open pits.
In addition to geologic units and structural features, these data include gravity observations and horizontal gravity gradient information.
Digital compilation and reinterpretation of published and unpublished geologic mapping of Alaska.
Digital compilation and reinterpretation of published and unpublished geologic mapping of Alaska.
Spatial databases for map units, strike and dip, geologic contacts, faults, dikes, in addition to a topographic base map are provided in an Esri file geodatabase. The geologic mapsheet is also provided as a PDF.
Known deposits, thickness of potash-bearing units, and permissive tracts with estimates of undiscovered resources.
Uninterpreted geophysical measurements and geochemical and mineralogical analytical data from samples collected during the summer field seasons from 2007 to 2010. Data are available in a single Geographic Information System (GIS) database.
Study focusing on the effects of historical mining on Forest Service lands in this area.
Deposits, prospects, and permissive tracts for porphyry and sediment-hosted copper resources worldwide, with estimates of undiscovered copper resources.
Regional locations and estimates of the probable amounts of undiscovered resources of copper, platinum-group elements, and potash in selected types of mineral deposits to depths of 1 to 3 kilometers below the surface of the earth worldwide.
MRDS describes metallic and nonmetallic mineral resources throughout the world. Included are deposit name, location, commodity, deposit description, geologic characteristics, production, reserves, resources, and references.
