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.
