Comments on the geologic information

  • Geologic Description = This prospect occurs in feldspathic schist near the western contact of Darby pluton granite. Sphalerite, galena, chalcopyrite, and pyrite have been identified (Miller and Grybeck, 1973). Stream sediment samples from the two drainages flowing west from this occurrence contained anomalous amounts of Pb in one case, and Pb and Zn in the other. The Darby pluton is a mid-Cretaceous granodiorite and granite; K/Ar ages for the Darby pluton are 88.3 +/- 1.5 and 92.8 +/- 2.6 Ma (Berry and others, 1976). The country rocks to the pluton here are high-grade metasedimentary rocks of Paleozoic or Precambrian age (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).
