Comments on the geologic information

  • Geologic Description = This occurrence is a weakly mineralized limonite gossan in garnet-chlorite-quartz schist and quartz-amphibole schist. The gossan occurs along a north-south-trending shear zone. Samples contain up to 10.0 ppm silver and 550 ppm lead (Flanigan, 1998). Also see NL012-016 and NL020-022.
  • Age = Flanigan (1998) interprets this gossan to be related to magmatic fluids from the Khotol pluton, based on its proximity to the pluton and its low molybdenum content . K-Ar and Ar/Ar dates for the Khotol pluton are approximately 110 Ma (Flanigan, 1998).
