Geologic, magnetic, and radiometric data collected at Dynamic Test Range - 1 (DTR-1) in Lake Mead, Arizona during an airborne survey for the purpose of developing a calibration standard for airborne gamma-ray detection systems in the National Uranium Resource Evaluation. The data includes concentrations of U, Th, and K in surface materials.

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

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)

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.

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.

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.

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.

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.

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.

From Introduction: "The Williams Quadrangle, Arizona (Fig. 1), was evaluated to identify geologic environments and delineate areas that exhibit characteristics favorable for uranium deposits. Evaluations were based primarily on surface investigations; only limited subsurface data were available."

Appendices containing uranium occurrence reports for the Williams Quadrangle in addition to chemical analyses and spectroscopic data of rock samples to accompany a report on U.S. uranium resources in Arizona.

From abstract: This abbreviated data report presents results of ground water and stream/surface sediment reconnaissance in the National Topographic Map Series (NTMS) Needles 1' x 2 quadrangle. Surface sediment samples were collected at 1672 sites, at a target sampling density of one site per 13 square kilometers (five square miles). Ground water samples were collected at 49 sites. Neutron activation analysis (NAA) results are given for uranium and 16 other elements in sediments, and for uranium and 9 other elements in ground water. Mass spectrometry results are given for helium in ground water. Field measurements and observations are reported for each site. Analytical data and field measurements are presented in tables and maps.
