These data generalize the detailed LR2000 information and related boundaries (for example, small mine claim boundaries) to a larger Public Land Survey System (PLSS) section boundary in order to assist in the analysis of locatable, leasable, and salable minerals for mineral-resource assessment. Data are provided in shapefile format.
Two high-resolution aeromagnetic surveys in south-central Colorado compiled to assess the subsurface geologic framework of the San Luis basin for ground-water flow model construction, and to map concealed faults potentially related to geothermal resources
U.S. Geological Survey (USGS) scientists have completed an assessment of the mineral-resource potential of nearly 10 million acres of Federal and adjacent lands in Idaho, Montana, Nevada, Oregon, Utah, and Wyoming. The assessment of these lands, identifie
