| Deposit | ACCORDING TO BAYLEY (1923), THE POISON BRANCH BELT IS A CONTINUOUS SERIES OF DEPOSITS, WITH EACH DEPOSIT COMPRISED OF A NUMBER OF NEARLY PARALLEL, CLOSELY SPACED VEINS. COMMERCIAL PORTIONS OF THE ORE BODIES ARE "...IN THE FORM OF VEINS OR DIKES OF RICH MAGNETITE THAT CUT MASSES OF LEANER ORE. THE LEAN ORE COMPRISES THE LENSES." BAYLEY DOES NOT DESCRIBE THE HOST ROCK, BUT IT IS PRESUMED TO BE CRANBERRY GNEISS, AS SHOWN ON THE GEOLOGIC MAP (RANKIN, ESPENSHADE, AND NEUMAN, 1972). ; INFO.SRC : 1 PUB LIT |
