Exploration Activity: Geothermometry At Salt Wells Area (Henkle, Et Al., 2005)
|Exploration Activity Details|
|Location||Salt Wells Geothermal Area|
|Activity Date||2004 - 2005|
Adsorbed mercury soil geochemical surveys and radiometric geophysical surveys were carried out in conjunction with geologic mapping to test the application of these ground-based techniques to geothermal exploration at three prospects in Nevada by Henkle Jr. et al. in 2005. Mercury soil vapor surveys were not widely used in geothermal exploration in the western US at the time, although the association of mercury vapors with geothermal fluids, hot springs, and/or soils has been recognized at the Steamboat Springs, NV, Roosevelt Hot Springs, UT, Dixie Valley, NV, Noya, Japan, and Moana, NV geothermal areas.
Warm spring waters were sampled from the Rock Springs and from an artesian water well located approximately 520 m to the west-southwest (about 33m basinward of the “Pony Express” fault scarp). Chemical analysis of the samples showed dissolved silica concentrations of 79.6 ppm for Rock Springs and 104 ppm for artesian well water, suggesting a potential reservoir temperature between 125°C and 139°C for faults of the "Pony Express" fault system, as determined using the quartz conductive geothermometer.
