| Deposit | LOWER PRECAMBRIAN 'W' (OR ARCHEAN) ROCKS OVERLAIN BY MIDDLE PRECAMBRIAN 'X' (OR MARQUETTE RANGE SUPERGROUP) ROCKS. LOWER PRECAMBRIAN W CRYSTALLINE ROCKS BLOCK FAULTED AND DIFFERENTIALLY RAISED AND LOWERED; FORMING TROUGHS. MIDDLE PRECAMBRIAN 'X' (OR MARQUETTE RANGE SUPERGROUP) ROCKS AS SEMI-CONSOLIDATED SEDIMENTS SLUMPED INTO THE TROUGHS. AT ABOUT THE SAME TIME ENTIRE AREA WAS REGIONALLY THERMALLY METAMORPHOSED, CREATING METAMORPHIC FACIES OR NODES. THE MARQUETTE DISTRICT AFFECTED BY THE REPUBLIC NODE, WHICH GRADES FROM CHLORITE TO SILLIMANITE ZONES, EXCLUSIVE OF KYANITE ONLY. SILLIMANITE ZONE IS IN VICINITY OF AND INCLUDES REPUBLIC TOWN AND REPUBLIC OPEN PIT. REST OF ZONED AREAS ARE REGULAR SHAPED, FAIRLY ROUND WITH SLIGHT FLATTENING TO THE NORTHEAST. (JAMES, H. L., 1955, P. 1455-1488) |

LARUE (1981) FOUND THAT CHEMICAL IRON SEDIMENTATION APPARENTLY TOOK PLACE WITH LITTLE REGARD TO BASINAL OR PLATFORM ENVIRONMENTS. BOTH ENVIRONMENTS SHOW PERIODS OF CHEMICAL-IRON SEDIMENTATION. HOWEVER, IN BOTH ENVIRONMENTS, DEPOSITION OF IRON WAS RESTRICTED TO PERIODS OF DETRITAL-SEDIMENT STARVATION. |
