Comments on the geologic information

  • Geologic Description = Miller and Grybeck (1973) report a small gossan in limestone; a grab sample of this gossan contained 500 ppm Cu, 300 ppm Pb, greater than 10,000 ppm Zn, and greater than 5,000 ppm Ba. Bedrock here is Paleozoic marble that is about 1.5 miles east of the Darby pluton (Till and others, 1986).
  • Age = Not known; probably mid-Cretaceous or younger. K/Ar ages for the nearby Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma (Berry and others, 1976).
