Carbon monoxide as a geothermal indicator at Meadow-Hatton KGRA, west-central Utah
Carbon monoxide (CO) was measured in soils over a Known Geothermal Resource Area (KGRA), located in west-central Utah. Attendant sampling of carbon dioxide (CO2) soil-gas was undertaken to compare with the spatial distribution of carbon monoxide anomalies. Anomalous CO data ranging up to 940 ppm are singularly grouped south of Devils Kitchen fault or rift in the vicinity of the KGRA. In contrast, the CO2 anomaly ranges up to 2.3% and is broader, forming a band extending northeastward in Pavant Valley. An active shallow groundwater regime apparently influences the upward migration of these gases into the soil horizon, resulting in sharply defined anomalies. It is suggested that CO is highlighting a local geothermal system with greater resolution than CO2 and should be more widely employed in geothermal investigations
