Comments on the geologic information

  • Geologic Description = The occurrence consists of sulfide-bearing amphibolite in a foliated series of mica schist, metavolcanics, and marble of Paleozoic age (MacKevett and Plafker, 1970). The amphibolite contained 0.15 percent zinc, 500 ppm copper, and weakly anomalous amounts of cobalt, nickel, titanium, and vanadium.
  • Ore Material = Sulfides

General comments

Subject category Comment text
Deposit Model Name = Mineralized mafic extrusive ?, Volcanogenic ?
Deposit Other Comments = the site is in Tongass National Forest and appears to be open for mineral location. The occurrence is low-grade, but of possible interest as a possible volcanogenic occurrence in layered metavolcanic rocks.
