Geothermal potential of three areas in southeastern Idaho and western Wyoming

Three areas in southeastern Idaho and western Wyoming have been determined to have significant geothermal potential based on their geologic environment, structural characteristics, and persistent microseismicity. Thermal manifestations at the three areas are somewhat dissimilar. The Afton, Wyoming, prospect is on the edge of a seismically active graben within the overthrust belt. Predominantly Mesozoic sedimentary rocks underlie the interest area. Thermal phenomena are limited to a small series of sulfur-precipitating hot (97/sup 0/C) springs. Grays Lake, Idaho, is near the boundary of the overthrust belt and the Snake River Plains. Few overt thermal manifestations are present, but the area is characterized by intense micro earthquake activity clustered spatially and temporarily, and by zones of anomalously low electrical resistivity. Soda Springs, Idaho, has a most prospective geologic environment including 40,000 year-old rhyolites, porous and permeable carbonate bedrock, and clustered micro earthquake epicenters. Thermal manifestations are common and intense. For more information on this resource, please see the link provided.
