Comments on the geologic information

  • Geologic Description = This occurrence is located adjacent to the mid-Cretaceous Quartz Creek quartz monzonite, a hook-shaped pluton that intrudes Jurassic-Cretaceous andesitic volcanic rocks. The pluton is surrounded by a N 15 W-trending alteration zone about 18 miles long and 2 to 5 miles wide. The altered volcanic rocks are marked by carbonate-quartz replacement, and possibly by tourmaline. A sample of gossan at the contact between quartz monzonite and andesite contained 1 ppm Au, 3,000 ppm As, 300 ppm Cu and 150 ppm Pb (Miller and Elliott, 1969, location 37).
  • Age = Mid-Cretaceous or younger.

General comments

Subject category Comment text
Deposit Model Name = Sulfides in altered andesite.
Deposit Other Comments = This site is one of numerous occurrences of argentiferous galena, sphalerite, pyrite and arsenopyrite in an 18-mile-long, 2- to 5-mile-wide zone of altered andesite surrounding the Quartz Creek quartz monzonite pluton. The altered zone trends N 15 W, across the drainage basins of Quartz Creek and the Kiwalik River.
