Comments on the geologic information

  • Geologic Description = Jasper (1967) reported the bedrock of the area to be quartz diorite and likewise, the float in the creek is quartz diorite. Pan concentrates in stream gravel contained up to 90 percent magnetite, 1 percent pyrite, up to 10% zircon, and locally up to 15 percent scheelite. ? Bedrock in the vicinity is the Willow Creek Pluton, a zoned pluton: the outer part consists of hornblende quartz diorite and lesser hornblende tonalite; the core consists of hornblende-biotite granodiorite, and lesser hornblende-biotite quartz monzodiorite and biotite quartz monzonite.
  • Age = Willow Creek Pluton is Late Cretaceous.
