Comments on the geologic information

  • Geologic Description = The Quartz Ledge prospect area is underlain by an assemblage of undivided Mesozoic or Paleozoic metamorphosed sedimentary, volcanic, and intrusive rocks; and by a stock and dikes of Cretaceous granodiorite and quartz diorite (Berg and others, 1988, p. 21, 22). The undivided assemblage was regionally metamorphosed to amphibolite grade in middle or Late Cretaceous Cretaceous time, and locally remetamorphosed to hornblende hornfels near the contacts of some of the granodiorite and quartz diorite plutons. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in amphibolite-grade metamorphic rocks, was staked for gold. No other information about it has been made public.
