“…The Steamboat Mountain Formation near the southwest corner of the Richfield quadrangle, like the adjoining older Blawn Formation, consists of both silicic and mafic volcanic rocks (Best and Davis, 1981). The silicic rocks are mostly rhyolite lava flows, with lesser associated ash-flow and airfall tuff and water-reworked tuff, distributed over an area more than 20 km across.…”

“…The altered areas range from small patches a few meters in diameter, to large areas as much as 7 km across. Some of the altered areas are closely localized along the northeast-trending Bible Spring fault zone (Best and Davis, 1981), or along its trend northeastward where it projects directly toward the Katie (Cima) sulfur-mercury deposit; other altered areas are more randomly scattered or are associated with local igneous centers of Steamboat Mountain age.…”

“…The mafic lava flows are minor in extent in the southern Wah Wah Mountains (Best and others, 1987), whereas the rhyolite lava flows are extensive in both the Wah Wah Mountains and the southern Indian Peak range (fig. 2): they reach the greatest thickness of 500 m at Steamboat Mountain (Best and Davis, 1981;Best and others, 1987).…”

“…A geologic map of the Mountain Spring Peak quadrangle was published at a scale of 1:24,000 by Best (1979); one of the Bible Spring quadrangle, to the west, was published by Best and Davis (1981); and the Teton quadrangle, to the north, was mapped by Best and Keith (1979). These maps at a scale of 1:24,000 and the accompanying descriptions of Oligocene and Miocene volcanic rocks in the area provided an excellent background for more detailed work.…”

“…Rhyolitic rocks with ages of 12-13 m.y. occur elsewhere in southwestern Utah, including the topaz rhyolite of the Steamboat Mountain Formation (Best, 1981). The K-Ar age of the rhyolite of Pinon Point is 12.8 ± 0.6 m.y.…”
