| Deposit | GROUP OF SUBPARALLEL, LOCALLY BRANCHING VEINS FORM A ZONE 15 M WIDE AND 230 M LONG. INDIVIDUAL VEINS ARE FROM A FEW CM TO 2 M WIDE, AND AVE. ABOUT 1 M IN WIDTH. IN THE VEINS, GRANITE HAS BEEN REPLACED BY SCHEELITE, CHALCOPYRITE, PYRITE, AND MOLYBDENITE IN A GANGUE OF QUARTZ AND CALCITE. SOME PYRITE AND CHALCOPYRITE DISSEMINATED THROUGH GRANITE FOR SEVERAL M AWAY FROM THE VEINS. THIN STRINGERS AND DISSEMINATED CRYSTALS OF SCHEELITE SCATTERED THROUGH MOST OF THE VEINS, BUT ARE MOST PROMINENT IN TWO SHOOTS AT THE SW END OF THE ORE ZONE. |
