Survey of Helium in Soils and Soil Gases and Mercury in Soils at Roosevelt Hot Springs Known Geothermal Resource Area, Utah
USGS-OFR--80-613 United States Department of the Interior, Geological Survey
The concentrations of helium and mercury in soils and of helium in soil gases were surveyed in part of the Roosevelt Hot Springs Know Geothermal Resource Area to see what relationship helium and mercury concentrations might have to geothermal features of the area. High concentrations of helium occurred over the producing geothermal field, in an area of high temperature gradients. Low concentrations of helium in soils occurred over an area of visible hydrothermal activity. High concentrations of mercury coincided with areas of high thermal gradients and low resistivity.
