Aggregate quarry in schists of the Inner Piedmont province of the Appalachian Orogen. Three main mineral forming environments are present. Ankerite veins contain fine ilmenite crystals and other well-formed rock-forming minerals. Prehnite veins in chloritic shear- and fracture-zones contain sharp prehnite crystals, some babingtonite, and various zeolites. Stilbite crystals are found in a fault zone at the northwest end of the quarry. Kainosite occurred in a one-time find where ankerite veins crossed a pegmatite containing large crude allanite crystals.
