Quaternary Borate Deposits As A Geothermal Exploration Tool In The Great Basin
Conference Paper: Quaternary Borate Deposits As A Geothermal Exploration Tool In The Great Basin
AbstractA close spatial relationship exists between Quaternary borate deposits and moderate to high temperature (>=150oC) geothermal systems in the western part of the Great Basin. Similarly, a strong correlation exists between high concentrations of boron in groundwater and geothermal activity in the Great Basin. These relationships hae special significance for geothermal exploraion becauase ina number of cases, Quaternary surface borates occur without associated springs, and thus the borates can, and are, serving as a guide to locating otherwise blind geothermal systems. Using borates as an exploation guide, and with key assistance from remote sensing techniques, three new geothermal targets have been identified in west-central Nevada at Rhodes, Teels, and Columbus Salt Marhas (playas). In each of these playas, geothermometry data from springs and wells suggest the possible presence of geothermal reservoirs at depth. Borate minerals are typically bright white in color and are difficult to distinguish visually from more common chloride and sulfate evaporites. For exploration for borates to be practical, it is essential to have an efficient means of identifying them in teh field. Kratt et al., (2006) have developed such means using field spectroradiometers and remote sensing methods.
