Maricopa county is the area of Arizona receiving top priority since it contains over half of the state's population. The county is located entirely within the Basin and Range physiographic region in which geothermal resources are known to occur. Several approaches were taken to match potential users to geothermal resources. One approach involved matching some of the largest facilities in the county to nearby geothermal resources. Other approaches involved identifying industrial processes whose heat requirements are less than the average assessed geothermal reservoir temperature of 110/sup 0/C (230/sup 0/F). Since many of the industries are located on or near geothermal resources, geothermal energy potentially could be adapted to many industrial processes.

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.

Pima County is located entirely within the Basin and Range physiographic province in which geothermal resources are known to occur. Continued growth as indicated by such factors as population growth, employment and income will require large amounts of energy. It is believed that geothermal energy could provide some of the energy that will be needed. Potential users of geothermal energy within the county are identified.

One hot spring and 33 wells drilled in the county discharge water at temperatures sufficient for direct-use geothermal applications such as process heat and space heating and cooling. Currently, one industry within the county has been identified which may be able to use geothermal energy for its process heat requirements. Also, a computer simulation model was used to predict geothermal energy on line as a function of time under both private and city-owned utility development of the resource.

Geothermal potential in Graham and Greenlee counties both of which contain significant quantities of geothermal energy that could be used for industrial, agricultural or residential use, is described. Projections are made of geothermal heat on line under both private and city-owned utility development. Potential users of geothermal energy, however, are limited since this area is sparsely populated and lacks an industrial base. Only a couple of industries were identified which could use geothermal energy for their process heat needs.

Activities included the identification and delineation of geothermal prospects, the comparison of conventional energy use patterns with geothermal sources, the preparation of area development plans and the compilation of detailed economic and energy data for each area. Current emphasis is on commercialization. (MHR)

Wells drilled in the county provide evidence of geothermal energy sufficient for process heat and space heating and cooling applications. Annual energy consumption was estimated for industries whose process heat requirements are less than 105/sup 0/C (221/sup 0/F). This information was then used to model the introduction of geothermal energy into the process heat market. Also, agriculture and agribusiness industries were identified. Many of these are located on or near a geothermal resource and might be able to utilize geothermal energy in their operations.

From abstract: This drilling project in northwestern Arizona consisted of 18 holes drilled to depths ranging from 1,341 to 5,491 feet (409 to 1,673 meters). The holes were sited to determine the lateral extent of the uranium-bearing, paludal/lacustrine strata of the Anderson Mine in Date Creek basin and to obtain additional data to improve the resource estimates for the Date Creek and Big Sandy basins.

This report contains aerial gamma-ray and magnetic quadrangle maps of portions of Arizona.

From foreword: This report is on the Arnold Mesa RARE II Further Planning Area, Yavapai County, Arizona.

From purpose: The purpose of this study was to examine the Precambrian conglomerates of central Arizona in sufficient depth to determine whether they contain any obvious uranium concentrations and whether their geologic environment of deposition was permissive or prohibitive of conditions favoring uranium concentration.

This report contains aerial gamma-ray and magnetic survey maps of the Lake Mead Dynamic Test Range.

From abstract: As part of the Department of Energy (DOE) National Uranium Resource Evaluation Program, a rotary-wing high sensitivity radiometric and magnetic survey was flown covering portions of the State of New Mexico, Arizona and Texas. The survey encompassed six 1:250,000 scale quadrangles, Holbrook, El Paso, Las Cruces, Carlsbad, Fort Sumner and Roswell.

From abstract: The part of Arizona south and east of Tucson is underlain by a wide assortment of deformed rocks, as well as by some major mineralized districts. A synthesis of the tectonic evolution of the region is offered in this report, which is based on older studies of mining districts and on more recent field studies by students and by the U.S. Geological Survey, augmented by field review and selective remapping of many key areas. Through this synthesis the rocks of the region are seen to have been deformed in response to diverse stresses, at various times, with an increasing degree of structural anisotropy of the rocks through time. Consequently, reactivated faults are common features, and segments of some of these faults record various kinds of movement, thereby providing unusual interpretive difficulties for many of the past local studies.
