Franciscan rocks in The Geysers Geothermal Resources Area (GRA) constitute a greatly deformed and chaotic assemblage of rocks known as melange which, under natural conditions, poses problems to slope stability. Unstable conditions inherent in the melange are accentuated by the steepness of slopes, chemical alteration of the rocks, and numerous faults and shear zones. Adverse effects that may be .experienced- with development of melange terrain can, however, be mitigated if potential problem areas are recognized before development begins and if good engineering geology·and engineering practices are followed.

The purpose of this project was to determine and evaluate possible geothermal resources for potential development at U.S. naval reservations in the greater San Diego, California area. The work was done through the auspices of a cooperative agreement between the U.S. Department of Energy, San Francisco Operations Office and the U.S. Department of Navy, China Lake Naval Weapons Center for joint research on geothermal energy at U.S. military installations.

This report presents the results of the California Division of Mines and Geology's (CDMG) geothermal resource investigation of the Sonoma Valley area, California. The study was undertaken to learn more about the known low-temperature (20°_90°C) geothermal resource in this area and. to assess the potential of the resource for development and use by the local community. The project was conducted in compliance with the terms of the fourth-year contract (1981-82) with the U.S. Department of Energy (DOE) under the state-coupled program and performed under CDMG's Phase II site-specific geothermal resources studies program.
