A total of five hot springs and 25 thermal wells are located within the combined counties. The water discharged from these hot springs and wells may be suitable for applications such as process heat and space heating and cooling. Within Cochise county there are two large firms which are capable of using 70/sup 0/C (158/sup 0/F) geothermal water for their process heat requirements but the potential use of geothermal energy in Santa Cruz county is limited due to the absence of industry within the county. The amount of geothermal energy on line as a function of time under both private and city-owned utility development is also predicted using a computer simulation model.

From introduction: During the spring and fall of 1979 the U.S. Bureau of Mines made a mineral investigation of the North End Roadless Area, including a literature search, a search of claim records in the Cochise County courthouse and the State office of the Bureau of Land Management, a search for mining claims and mineralized zones, and examination of known mines and prospects. Local residents and officials of mining companies the U.S. Forest Service, and Arizona State government agencies provided information regarding mining activity and mineral deposits.

From summary: In January-April 1984, the Bureau of Mines conducted a mineral survey of the Lower Burro Creek Wilderness Study Area as required by Federal Land Policy and Management Act (Public Law 94-579, October 21, 1976). The Lower Burro Creek Wilderness Study Area comprises 21,700 acres in southeastern Mohave and Yavapai Counties, Arizona. Mines and prospects are located on deposits and (or) occurrences of gold, bentonite, magnesite, and agate in the eastern and southeastern part of the study area.

From abstract: Information in this report supplements the geologic map of the Stanford Canyon quadrangle that provides chemical data, thin sections, and hand specimens for each of the samples collected in the quadrangle.

From introduction: This report supplements similar reports prepared for the four 7.5-minute quadrangles that cover the Turkey Creek caldera and geologic map of the caldera.

Report discussing a reconnaissance study performed in September and October 1954 of the Bisbee district in Cochise County, Arizona. The purpose of the study was to determine the area's suitability for a detailed study of the relation between uranium and hypogene mineral zoning.

From abstract: This report describes the comprising the western two-thirds of the Pearce quadrangle and the eastern two-thirds of the Benson quadrangle of the Geological Survey's Topographic Atlas of the United States and includes about 1,400 square miles in the west-central part of Cochise County, Arizona.

This report includes two maps of the same location, one describing water-level contour, well depth in which depth to water was measured, the other describing well from which water sample was collected and irrigated areas. It includes a letter from the district chief of the United States Department of the Interior to users of the geological survey hydrologic data.

Technical report issued by the Bureau of Mines over the different uses of gypsum. The sources and uses of gypsum are presented and discussed. This report includes tables, photographs, and illustrations.
