Comments on the geologic information

  • Geologic Description = Only indication of occurrence is report by U.S. Bureau of Mines (1995) as an asbestos deposit.? the bedrock in the vicinity of the occurrence is Tertiary volcanic rocks. The rocks of this unit include: rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows (Nelson and others, 1983; unit Tv). Potassium-argon ages for this unit (Tv) range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
  • Age = Tertiary or younger; potassium-argon ages for this unit (Tv) range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
  • Age = Chron age is for Host Rock.
