Mineral resource potential map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana Mineral resource potential map of the Selway-Bitterroot Wilderness, Idaho County, Idaho, and Missoula and Ravalli counties, Montana
Mineral resource studies by the U.S. Bureau of Mines and the U.S, Geological Survey indicate that five areas within the Selway-Bitterroot Wilderness have mineral resource potential. Regional studies suggest that three granitic plutons within the wildemess, the Running Creek pluton on the southwestern border of the wildemess, the Painted Rocks pluton on the southern border of the...
Mineral resource potential map of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas counties, Colorado Mineral resource potential map of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas counties, Colorado
A geologic and geochemical investigation and a survey of mines and prospects have been conducted to evaluate the mineral resource potential of the Spanish Peaks Wilderness Study Area, Huerfano and Las Animas Counties, in south-central Colorado. The·study area is underlain by sedimentary rocks of Paleozoic to Tertiary age (Johnson, 1969). Stocks and dikes were emplaced between 20 and 25 m...
Mineral resource potential map of the Stansbury Roadless Area, Tooele County, Utah Mineral resource potential map of the Stansbury Roadless Area, Tooele County, Utah
The U.S. Bureau of Mines and the U.S. Geological Survey have conducted a survey to determine the mineral resource potential of the eastern part (D4757) of the Stansbury Roadless Area, Tooele County, Utah. The results of this survey indicate that a low to moderate potential for copper, lead, and silver mineralization exists in part of area D4757. The balance of area D4757 is considered to...
Mineral resource potential map of the Sugarloaf Roadless Area, San Bernardino County, California Mineral resource potential map of the Sugarloaf Roadless Area, San Bernardino County, California
Geologic, geochemical, and geophysical investigations and a survey of mines and prospects indicate that the Sugaloaf Roadless Area contains subeconomic graphite and magnesian marble resources. Parts of the area have a low potential for the occurrence of additional low-grade graphite resources, but there is no potential for additional magnesian marble resources within the roadless area...
