Comments on the geologic information

  • Geologic Description = The only information is that the U.S. Bureau of Mines (1995) reported as a lode gold and silver 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 = Potassium-argon ages for unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978) indicating a Tertiary age for the host rocks to the mineralization.
  • Age = Host rock is Tertiary.
