Comments on the geologic information

  • Geologic Description = The location of this site is approximate. Reed and others (1978) describe a float sample of quartz semischist that contains unknown secondary hydrous copper carbonate minerals. The sample site lies near a thrust fault that places Devono-Mississippian(?) black shale and calcareous sedimentary rocks (Pzsl), considered to correlate with the Totalanika Schist in the Kantishna Hills to the north, over a lower Paleozoic quartzite, semischist, and metavolcanic rocks (Pzsv) (Reed and Nelson, 1980).
