Preliminary Geologic Map of the Wildcat Creek Area, Eastern Beaver County, Utah

Abstract

Although the area around Wildcat Creek in eastern Beaver County is shown on the Geologic Map of the State of Utah (Hintze, 1963) to be comprised of Tertiary Sevier River Formation, field investigation has revealed a variety of rock types, mostly igneous. In view of the geothermal potential near Cove Fort and Sulphurdale to the northeast, a geologic map correcting this discrepancy would be of vital interest to companies exploring the geothermal potential of the area. A preliminary geologic map of the Wildcat Creek area (figure 1) was made in August, 197 6, using aerial photos at a scale of 1: 36,500. The mapped area lies between the Mineral Mountains and Interstate 15 and encompasses about 14 x 23 km (8 x 14 miles). It is dominated by a series of north trending ridges and washes, influenced by Basin and Range block faulting, and by a line of silicic lava domes
