Comments on the geologic information

  • GEOL.DESC: GREEN AMPHIBOLITE SCHIST, LOCALLY CALLED GREENSTONE, IS MINED FROM THE 200' LEVEL OF THE TRYON MINE. THE PRODUCTS ARE STUCCO DASH, PASSING 3-MESH AND RETAINED ON 4-MESH; ROOFING ROCK, PASSING 1/2", RETAINED ON 4-MESH; ROOFING GRANULES, RUNNING ABOUT 25% OF 14-MESH, 50% OF 20-MESH AND 25% OF 40-MESH. A LARGE PART OF THE FINAL PRODUCT IS TOO FINE FOR THE ABOVE USES, AND THE FINDING OF A MARKET FOR IT IS A PROBLEM.
