Comments on the geologic information

  • Geologic Description = The country rocks near the head of Annette Bay are recrystallized, Upper Jurassic or Cretaceous andesitic or basaltic flows and tuff, and a stock of quartz metadiorite that may be cogenetic with some of the volcanic rocks (Berg, 1972 [I 684]; Karl, 1992). The rocks were regionally metamorphosed to greenschist-grade phyllite and semischist in Late Cretaceous time. The site has been described only as a reported occurrence of antimony and copper minerals (Berg and Cobb, 1967, p. 180).
