Ore body information

  • General form LENS
    Length 60.96M
    Width 22.86M

Comments on the geologic information

  • THE COUNTRY ROCK IS MEDIUM GRAINED QUARTZ-BIOTITE GNEISS THAT STRIKES N 30 E AND DIPS 40-50 SE. THE GNEISS IS LOCALLY HIGHLY CONTORTED AND CONTAINS NUMEROUS POPS AND STRINGERS OF QUARTZ AND PEGMATITE. THE CONTACT ZONE IS FROM 1 TO 2 FEET WIDE AND IS COMPOSED OF SCHISTOSE CHLORITE AND VERMICULITE. IT IS IN SHARP CONTACT WITH DEEPLY WEATHERED PERIDOTITE ON ONE SIDE AND IS BORDERED ON THE OTHER BY A 1 FOOT THICK QUARTZ VEIN AND A NARROW PEGMATITE DIKE. AN AMPHIBOLITE DIKE INTRUDES THE PERIDOTITE. THE DIKE IS 8 FEET WIDE AND CROPS OUT ABOUT THE CENTER OF THE CUT AND NEAR THE BASE. IT IS A BLACK MASSIVE, EQUIGRANULAR MEDIUM-GRAINED ROCK COMPOSED OF HORNBLENDE AND PLAGIOCLASE. ASBESTOS OCCURS AS THIN CROSS-FIBER VEINS AND AS MASS-FIBER ORE OF THE PERIPHERAL ZONE VARIETY.
