Comments on the geologic information

  • Geologic Description = MacKevett and Holloway (1977) reported altered zones at this occurrence, probably related to Tertiary granitic rocks. No exposures of granite rocks were found in the area during U.S. Geological Survey studies in the mid-1980's (Wilson and others, 1988). Instead, these studies indicated extensive silicification and calcification of siltstone and sandstone of the Cretaceous Staniukovich Formation. A rock sample of olive-green siltstone was reported to be anomalous in copper and zinc (Wilson and others, 1987).
  • Age = Cretaceous or younger.
