Comments on the geologic information

  • Geologic Description = The country rocks on eastern Gravina Island are Upper Jurassic or Cretaceous marine andesitic or basaltic volcanic rocks interbedded with subordinate flyschlike sedimentary rocks (Berg, 1973; Berg and others, 1988). These strata were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time. According to U.S. Bureau of Mines claim records (1977), this prospect, which appears to be in andesitic or basaltic metavolcanic rocks, was staked for gold. No other information about it has been made public.
