  • PERIDOTITE WAS COMPLETELY REMOVED THERE. THE COMPOSITION AND RELATIONSHIPS OF THE ASBESTOS IS UNKNOWN. A FEW LOOSE BLOCKS ON THE DUMP INDICATE THE BODY WAS IN PART ALTERED DUNITE THAT CONTAINED NUMEROUS CROSS-FIBER VEINS OF ASBESTOS. COUNTRY ROCK IS COARSE GRAINED QUARTZ-BIOTITE GNEISS THAT CONTAIN PODS AND STRINGERS OF PEGMATITE. IT STRIKES N 15 E AND DIPS 70 NW. THE PEPIDOTITE WAS CONFORMABLE TO THE FOLIATION OF THE GNEISS.
