Report on Geophysics Surveys for the Desertron Maricopa and Sierrita Sites, June 3-20, 1987

Bryan, Wayne C., Burchard, Gary C., Byrne, Randall W., Condit, Thomas B., DeHart, Brian J., DuPass, Mary K., 1961-, Loy, Kenneth Lindsay, 1959-, Sternberg, Ben K., Thomas, Scott J., 1961-, Umholtz, Adam C., Wilkosz, Mary Elizabeth. 20 June 1987 (has links)
Geophysical investigations were conducted at the proposed Maricopa SSC site in support of the geotechnical program for the State of Arizona site proposal. Modeling of a gravity survey across Rainbow Valley showed that the minimum depth to bedrock in the center of this basin is 750 meters (2500 feet). Gravity and magnetic surveys in Maricopa Valley between the north and south Maricopa Mountains indicated the possible presence of faults and diabase dikes. Seismic refraction surveys in the area of the proposed Injector Ring complex indicated a buried bedrock ridge about 400 meters (1300 feet) wide and approximately 25 meters (80 feet) below the surface. Geophysical surveys were also conducted at the Twin Buttes Mine near the proposed Sierrita SSC site. These surveys included gravity, seismic refraction, seismic reflection, DC resistivity and IP, and CSAMT surveys. Since the geology and geotechnical properties at the Twin Buttes mine are very well documented from extensive drilling, these surveys provide a calibration of observed geophysical signatures over various rock types.

Geophysical surveys were conducted in the Pima mining district by students from the University of Arizona. The surveys were concentrated along section B-B' from Cooper (1973). The objectives of this survey included: teaching geophysical techniques, mapping regional structure along this profile, and determining which geophysical techniques were most useful for regional .mapping in this area. Controlled source audio-frequency magnetotelluric (CSAMT) surveys successfully mapped depth to basement along this profile. Seismic refraction surveys were not able to map depth to basement. Either the depth to basement was beyond the range of the arrays used in this experiment or there is insufficient contrast in the velocity between the basement and the overlying rocks. A test of the seismic reflection method was carried out using a walk-away noise spread. Possible reflections from basement were noted but were not sufficiently diagnostic to be routinely use able.
