Abstract
The geothermal potential of Range Bravo 19, a bombing range, located 18 miles south of NAS, Fallon, Nevada has been evaluated as part of an ongoing Navy program. Geological and thermal gradients data were obtained from five, 500 ft. drill holes. Gradients ranged from 7°C/100 m to 10.4°C/100 m. Soil geochemistry located three areas with mercury contents over 20 ppb, with a threshold of 5 ppb. Water geochemistry using analyses from Lee Hot Springs, two cold springs and one drill hole, using the various geochemical thermometers and models gave reservoir temperatures of from 13 to 240°C. Combining the data indicates a possible geothermal reservoir in the northwest portion of the range with a probable temperature of about 170°C.
