Exploration Basis
1) Estimate thermal regime and thermal potential of the system. 2) Use field mapping to develop a model of the reservoir system.
1) The seismograms of 44 events recorded by the telemetered array and nine events by the Centipede array were analyzed using the reduced spectral ratio technique to determine the differential attenuation factor delta t* for the events recorded with the highest signal-to-noise ratio. 2) Arcuate faults in the Coso Range are interpreted to have been produced by the regional stress field rather than to have been of volcanogenic origin. Focal mechanisms of small-magnitude earthquakes support the stress directions indicated by local fault patterns. Fumeroles in the area are primarily associated with oblique slip faults rather than with arcuate or ring faults. The geothermal reservoir is therefore much different from that of a caldera or subsidence bowl, and the overall geothermal potential is probably less than earlier estimates.
