Mineral resource potential map of the Hells Hole further planning area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico Mineral resource potential map of the Hells Hole further planning area (RARE II), Greenlee County, Arizona, and Grant County, New Mexico
During 1979, the U.S. Geological Survey and the U.S. Bureau of Mines conducted field investigations to evaluate the mineral resource potential of the Hells Hole Further Planning Area. The investigations included geologic mapping, geophysical studies, geochemical sampling, and a survey of known mines, prospects, and mineralized areas. This report summarizes the results of those studies.
Mineral resource potential map of the James River Face Wilderness, Bedford and Rockbridge counties, Virginia Mineral resource potential map of the James River Face Wilderness, Bedford and Rockbridge counties, Virginia
The rocks in the James River Face Wilderness are shales and quartzites that overlie a meta-igneous basement. They are folded into a large southwestward-plunging anticline that is cut off on the east and south by an extensive thrust fault that brings old basement rocks over the younger sedimentary rocks. Geochemical studies of stream sediments, soils, and rocks do not reveal any unusually...
Mineral resource potential map of the John Muir Wilderness, Fresno, Inyo, Madera, and Mono counties, California Mineral resource potential map of the John Muir Wilderness, Fresno, Inyo, Madera, and Mono counties, California
Under the provisions of the Wilderness Act (Public Law 88-577, September 3, 1964) and the Joint Conference Report on Senate Bill 4, 88th Congress, the U.S. Geological Survey and the U.S. Bureau of Mines have been conducting mineral surveys of wilderness and primitive areas. Areas officially designated as "wilderness," "wild," or "canoe" when the act was passed were incorporated into the...

Mineral resource potential map of the lower San Francisco Wilderness study area and contiguous roadless area, Greenlee County, Arizona and Catron and Grant Counties, New Mexico Mineral resource potential map of the lower San Francisco Wilderness study area and contiguous roadless area, Greenlee County, Arizona and Catron and Grant Counties, New Mexico
The Lower San Francisco Wilderness Study Area consists of a narrow strip 1-2 mi (2-3 km) wide between the rims of the San Francisco River canyon. The wilderness study area has a moderately high potential for geothermal resources, a low to moderate potential for base metal or precious metal resources in middle to upper Tertiary volcanic rocks, essentially no oil, gas, or coal potential...
