Abstract
Simple conceptual models have been developed to explain the nature of many geothermal systems in the Basin and Range physiographic province. Models are characterized by range bounding normal faults which separate high thermal conductivity bedrock from low thermal conductivity valley fill, and along which geothermal fluids may circulate. Modeling results suggest that information on the temperature of the fluid, dip of the fault, and vertical extent of the fluid circulation is contained in the heat flow anomaly pattern. Such information is valuable for exploration decisions. The models will be illustrated for geothermal anomalies at Vale Hot Springs KGRA, Oregon and Roosevelt Hot Springs KGRA, Utah.
