Comments on the geologic information

  • Shear zone near phyllite-granodiorite contact. Paleozoic Orogenic Belt (Blue Ridge-Piedmont area of the Appalachian Mountains)
  • MAJOR POST-ORE GEOLOGIC EVENT: CROSSCUTTING STEEP AND FLAT JOINT SETS; SEVERAL TRI DIABASE DIKES. VEINS CONTROLLED BY SHEAR ZONE AT SMALL ANGLE TO FOLIATION IN PHYLLITE AND PLUTON; MAJOR ORE BODIES OCCUR AS STEEPLY SSW PLUNGING OVERLAPPING ON ECHELON QUARTZ PODS, MOSTLY IN SCHIST BUT ALSO IN GRANODIORITE.
