Comments on the geologic information

  • Geologic Description = Molybdenum claim in rhyolite and associated granite bodies (Nelson and others, 1983; unit Tv). Unit Tv includes rhyolitic breccia, ash-flow tuff, flows, and intrusive rocks and subordinate mafic to intermediate flows. MacKevett and Holloway (1977) speculated that the claim is located in an area of quartz veining. Potassium-argon ages for Unit Tv range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
  • Age = Tertiary or younger; potassium-argon ages for the host rock range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
  • Age = Chron age is for Host Rock.
