Comments on the geologic information

  • Geologic Description = This occurrence is within or near the Agripina Bay batholith of Pliocene and/or Miocene age, and represents numerous altered zones which are said to be in the general vicinity and probably associated with the batholith (MacKevett and Holloway, 1977; Detterman and others, 1987). An altered quartz-sericite sample from this area has been dated as Pliocene in age (Wilson and Shew 1992).
  • Age = Pliocene
