Comments on the geologic information

  • Geologic Description = At this occurrence a quartz diorite pluton of Pliocene age (Wilson and Shew, 1992) cuts sedimentary rocks of the Jurassic Naknek Formation. Case and others (1988) report large magnetic anomalies associated with the pluton. It has been suggested that the anomalies are due to magnetite-rich segregations in mafic phases of the pluton (MacKevett and Holloway, 1977). Skarn-type mineralization may also account for the anomalies. In the past the area has been staked as lode claims for iron.
  • Age = Pliocene
