Comments on the geologic information

  • Geologic Description = Richter (1967) reported scheelite in Fall Creek stream-sediment concentrate samples. Fall Creek drains Valdez Group metasedimentary rocks of Late Cretaceous age. Winkler (1992) describes the rocks as thick sequences of drab, rhythmically alternating, multiply deformed turbidite. Lithologies include: metasandstone, metasiltstone, argillite, slate, and phillite, and rare beds of pebbly argillite and metasandstone.
