Comments on the geologic information

  • GEOL.DESC: VEIN CROPS OUT IN AMPHIBOLITE SCHIST NEAR, WESTERN CONTACT OF SCHIST WITH BLACK SLATES WITH SILICEOUS BEDS THAT SHOW A CHARACTERISTIC FLUTING. THE AMPHIBOLITE SCHIST IS FINE-GRAINED AND GRAY-GREEN. A DISCONTINUOUS BARREN OR "BULL" QUARTZ VEIN MARKS THE EAST BOUNDARY OF INTENSE MINERALIZATION AND THIS VEIN MARKS A SHARP ANGLE WITH THE PRODUCTIVE NORWEGIAN VEIN WHICH IS 4 TO 20 INCHES THICK. A VEIN 12 FT. IN THE FOOTWALL OF THE NORWEGIAN VEIN, COMPOSED OF QUARTZ AND ANKERITE WAS EXPOSED AT THE 300 FT LEVEL, CUTTING ACROSS THE WEST DIPPING STRATA. A RICH POCKET WAS DEVELOPED AT THE INTERSECTION OF THIS VEIN AND THE BLACK SLATE. DUE TO THE REVERSE DIP DIRECTION OF THEVEINS COMPARED TO THE STRATA, SEVERAL DIFFERENT ROCK TYPES ARE ENCOUNTERED AT DEPTH.
