Sedimentary Rocks as Geothermal Aquifers and Reservoir Rocks

Field Trip Leaders: Joe Moore and Rick Allis

Carbonate rocks host thermal aquifers throughout large parts of Utah and eastern Nevada. In central Utah, carbonate rocks form the reservoirs of the productive geothermal systems at Cove Fort and Thermo. The fluids discharge in the Black Rock Desert, where a deep oil exploration well, Pavant Butte-1 encountered temperatures of ~ 250°C at 3 km. The desert gets its name from the Quaternary basalts and andesite cones and flows scattered throughout the region.

The field trip will include stops at hot springs and extensive travertine deposits in the Black Rock Desert and the Cove Fort geothermal system.
