| Deposit | MINERALIZATION OCCURS IN A 50-FOOT THICK DOLOMITE BED WHICH IS IN THE BASAL KINGSPORT FORMATION. KENT IMPLIES THAT MINERALIZATION IS RELATED TO FAULTING AND BRECCIATION. SPHALERITE OCCURS IN INTERSTICES OF BRECCIA WITH GANGUE DOLOMITE. BRECCIA MATRIX INCLUDES SPHALERITE, DOLOMITE, CHERT, AND SMALL AMOUNT OF PYRITE. MINERALIZATION IS LOCALLY QUITE RICH.PARTLY OXIDIZED SULFIDE ORE IS COMMONLY COATED WITH GREENOCKITE. ; INFO.SRC : 1 PUB LIT |
