Comments on the geologic information

  • Geologic Description = This occurrence is located adjacent to the mid-Cretaceous Quartz Creek pluton, a hook-shaped, quartz monzonite body. The pluton is surrounded by a N 15 W-trending alteration zone about 18 miles long and 2 to 5 miles wide. The alteration zone is in Jurassic-Cretaceous andesitic volcanic rocks, and is marked by carbonate-quartz replacement, and tourmaline. Fine-grained dikes of varying composition cut the andesites near the pluton. Dikes near the Quartz Creek pluton are locally mineralized. At this occurrence, disseminated scheelite occurs in pyrite-tourmaline-quartz vein material in frost-riven rubble near the contact between andesite and quartz monzonite. A grab sample from location 36 contained 500 ppm Cu, 150 ppm Pb, and greater than 1% W (Miller and Elliott, 1969).
  • Age = Mid-Cretaceous or younger.

General comments

Subject category Comment text
Deposit Model Name = Scheelite in pyrite-tourmaline-quartz veins.
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.
