Comments on the geologic information

  • Geologic Description = A small open cut exposes a 15-foot-wide quartz vein (Chapin, 1914, B 592-J, p. 321-355). An adit driven to crosscut the vein intersected a brecciated mass of schist with small quartz veins; free gold was panned here from crushed rock (Chapin, 1914, B 592-J, p. 321-355). This prospect lies on the western edge of a Cretaceous granite that intrudes two units of the Fairbanks Schist that are composed of (1) quartz-muscovite schist, quartzite, and chlorite-quartz schist, and (2) amphibolite, magnetite-rich biotite schist, quartz schist, and marble (Newberry and others, 1996).
