Comments on the geologic information

  • Geologic Description = A quartz vein reportedly occurs between two felsic dikes in Late Cretaceous Valdez Group black slate and metasandstone. The vein is 30 inches wide, traceable for 600 ft, and contains pyrite, arsenopyrite, chalcopyrite, and galena (Roehm, 1938).
  • Age = Late Cretaceous or younger; vein occurs between two felsic dikes in black slates and metasandstones of the Late Cretaceous Valdez Group.
