Assembling Crustal Geophysical Data for Geothermal Exploration in the Great Basin, Louie and Coolbaugh. We have compiled velocity information from sources in the literature, results of previous seismic experiments and earthquake-monitoring projects, and data donated from mining, geothermal, and petroleum companies. We also collected (May 2002 and August 2004) two new crustal refraction profiles across western Nevada and the northern and central Sierra. These sections had not been well characterized previously. About half of the first project year's budget was devoted to acquisition of seismic recording and computer equipment to support the collection of refraction data and dissemination of our results. This equipment was acquired two years ago and has been in constant use. More than two dozen graduate and undergraduate students from UNR have participated extensively in project activities, in capacities ranging from instrument deployment, through data analysis, to presentations at international professional meetings. A third regional refraction experiment is funded for the next project year. The seismic velocity model resulting from our selection of new and legacy data is available on the web at www.seismo.unr.edu/geothermal. We have made a final interpretation of the crustal thickness and velocity results gained during the May 2002 field project, which suggests very thin (<25 km) crust in a limited area of central Nevada near Battle Mountain, on the Humboldt Lineament. Interesting geochemical and GPS anomalies are also present in this area.
