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