Comments on the geologic information

  • Geologic Description = Area of widespread zinc and trace lead anomalies associated with silicified zones in felsic volcanic rocks. Several zones of intense fracturing and iron-staining contain 1 percent to 3 percent pyrrhotite or pyrite. Samples taken from zones of intense fracturing and iron-staining yielded values of 220 to 260 ppm Zn (Resource Associates of Alaska, 1976). The volcanic rocks 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 Unit Tv range from 56.2 to 62.7 m.y. indicating a Tertiary age for these rocks (Eakins and others, 1978).
  • Age = Tertiary; volcanic host for mineralization has potassium-argon ages that range from 56.2 to 62.7 m.y. (Eakins and others, 1978).
  • Age = Chron age is for host rock.
