Comments on the geologic information

  • Geologic Description = Only information is reported by the U.S. Bureau of Mines (1995) as a lode gold deposit.? the geologic map (Nelson and others, 1983) indicates undivided Quaternary deposits in the area of the occurrence. Bedrock is about 2.8 km north and south of the occurrence. To the north, the bedrock consists of Tertiary volcanic rocks (Tv) and Cretaceous to Tertiary medium-grained granite (TKi11). The volcanic rocks include rhyolitic breccia, ash-flow tuff, flows, felsic intrusive rocks, and subordinate mafic to intermediate flows. Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978). To the south, the bedrock is Tertiary mafic to intermediate volcanic flows (Nelson and others, 1983; unit Tvf).?
