Comments on the geologic information

  • Geologic Description = This site is marked by a color anomaly approximately 1 by 3 miles in extent (Cox and others, 1981). It has been described as a porphyry-type occurrence in Tertiary intrusive rocks (MacKevett and Holloway, 1977). This occurrence may be related to a dacite plug dome (Detterman and others, 1981). Nearby drainages are anomalous in tin and zinc.
  • Age = Tertiary.
