Exploration Basis
A reflection survey was done to analyze the brittle upper plate structure revealed by reflection seismic data
The relationships between upper crustal faults, the brittle-ductile transition zone, and underlying magmatic features imaged by multifold seismic reflection data are consistent with the hypothesis that the Coso geothermal field, which lies within an extensional step-over between dextral faults, is a young, actively developing metamorphic core complex. The reflection images were processed using a non-linear simulated annealing approach to invert P-wave first arrivals in the seismic data for 2-D velocity structure. The combination of magmatic heat and active normal faulting in the regional transtensional setting establishes the conditions for hydrothermal convection in the Coso geothermal field.
