Comments on the geologic information

  • Geologic Description = Several rock units are within the area prospected for gold by John Rogach. Cretaceous dikes have intruded the Fairbanks Schist, which is composed of quartz-muscovite schist, quartzite, and chlorite-quartz schist (Newberry and others, 1996). Amphibolite, marble, and biotite schist are also found in the area around the Rogach prospects at the head of Nugget Creek. In the fall of 1938, the workings at the prospect consisted of pits and shallow shafts (Reed, 1938, p. 5).
