Inversion modeling of multiple geophysical data sets for geothermal exploration: application to Roosevelt Hot Springs area. Final report
The theoretical basis for modeling the arrival times of local earthquake P waves at a network of seismic stations is described. A technique for separating the dependence of network arrival times on velocity structure from the dependence on the earthquake location parameters is presented. Commented computer listings of the forward modeling algorithms developed in part under DOE support are given. The local arrival time and Bouguer gravity data sets acquired for the Roosevelt and Leach Hot Springs areas are described. The Leach data were found to be inadequate so the emphasis is on the editing and processing the Roosevelt Hot Springs data prior to inversion. The inversion model for the Roosevelt Hot Springs area obtained from a joint inversion of seismic and gravity data is described. The more robust features of the final model are discussed in light of the known geology and geophysics of the area and are compared to results obtained from related studies. (MHR)
