Ore body information

  • Strike N 5 E
    Dip 60 E
    Thickness 0.91M

Comments on the geologic information

  • GEOL.DESC: SMALL BODY OF OXIDE ORE 3 FT. THICK, LIES ENCLOSED IN AND PARALLEL TO THE BEDDING OF THIN-BEDDED GREEN RADIOLARIAN CHERTS, WHICH STRIKE N 5 E AND DIP 60 E. CONTACT BETWEEN ORE AND CHERT IS SHARP ON BOTH SIDES. ORE BECOMES MORE SILICEOUS CLOSE TO OUTER SURFACE, AND OUTER 2 INCHES ARE GREY CHERT BANDED WITH MANGANESE STREAKS. THIS IS SEPARATED FROM GREEN CHERT BY SHALE PARTING. ORE IS CUT BY FEW QUARTZ VEINS, AND CONTAINS SOME SILICA SKELETONS.
