Abstract
Lithologic and structural patterns in the Beowawe KGRA as inferred from resistivity an shallow seismic reflection data are consistent with mapped geologic units and structures and with the logs of two deep geothermal test holes. The spectacular surface phenomena at the Geysers mark an area where several fault patterns intersect. East-northeast and northwest normal faults control hot spring distribution and structural blocks in a thick sequence of basaltic andesitic flows overlying minor tuffs and the Ordovician Valmy Formation. A similar structural complexity occurs in Horse Heaven, 4 miles southwest of the Geysers.
