Helium in soil gases of the Roosevelt Hot Springs Known Geothermal Resource Ares, Beaver County, Utah
Soil samples were collected in two parallel traverses across the Dome fault zone of the Roosevelt Hot Springs Known Geothermal Resource Area. The samples were sealed in air-tight aluminum cans, and the soil gas was allowed to equilibrate with the atmospheric air in the cans. Gas from the cans was analyzed by mass spectrometry. Samples collected over faults contained anomalously high concentrations of helium. Samples collected close to a geothermal well 884 m deep contained more helium than samples collected near another geothermal well 1370 m deep.
