Book excerpt: At the request of the Bureau of Land Management and under authority of the Federal Land Policy and Management Act of 1976, the Bureau of Mines conducted a mineral survey in February 1988 to appraise the mineral resources of 16,430 acres of the 17,645-acre Planet Peak Wilderness Study Area, La Paz County, Arizona. Prior to field study, Bureau personnel reviewed geologic literature and talked to several knowledgable people about mining and minerals in the area. The study area is in a region characterized by low angle, extensional dislocation surfaces known as detachment faults. The Buckskin-Rawhide detachment fault cuts across the western part of the study area. West of the fault, on the hanging wall or upper plate, the rocks are chiefly Paleozoic-age carbonate rocks and Tertiary-age sedimentary rocks. East of the fault, on the foot wall or lower plate, the rocks are granitic gneiss, locally mylonitic. Gold deposits are associated with detachment faults at several localities in the Southwest. No mineral resources were quantified at the surface in the study area; however, detailed exploration work in the Pride Mine area might define extensions, possibly into the study area, of the previously mined ore deposits. Trace element anomalies in samples from the study area indicate that mineralization similar to that which occurred at the Copperstone Mine (a newly operational gold mine 25 mi to the south) occurred in teh study area, most notably at the Pride Mine. Sand and gravel in teh study area are not unique and thus are not valuable as a resource. The oil and gas potential is rated low to zero by the U.S. Geological Survey; the Arizona Bureau of Geology and Mineral Technology has not identified any prospective geothermal sources in the study area.
