| Abstract |
Electrical conductivities o spring waters in the Stillwater Range, the August, Clan Alpine and Desatoya Mountains, indicating varying levels o ionic concentration, were complied. Anomalously high ionic concentrations are largely limited to the northern Stillwater range. High levels of sulfate, chloride, and bicarbonate may to a certain extent be derived form mineralized and scapolitized zones and limestone's in Mesozoic sedimentary and igneous rocks. However, the highest bicarbonate levels are found in springs emerging from igneous rocks. Their close proximity to a major fault and the occurrence of high CO2 pressures in the Dixie Valley geothermal system may suggest a geothermal source of CO2 beneath the Stillwater Range. |
