| Deposit | THE GEOLOGY CONSISTS OF PRECAMBRIAN W CRYSTALLINE ROCKS OVERLAIN BY PRECAMBRIAN X SEDIMENTARY ROCKS. DURING PRECAMBRIAN X TIME, PRECAMBRIAN W ROCKS BLOCK FAULTED AND DIFFERENTIALLY RAISED; LOWERED; FORMING TROUGHS. PRECAMBRIAN X SEDIMENTS SLUMPED INTO THE TROUGHS. AT ABOUT THE SAME TIME, THE ENTIRE AREA WAS REGIONALLY THERMAL METAMORPHOSED. THIS AREA OF THE MENOMINEE DISTRICT IS IN THE CHLORITE AND BIOTITE ISOGRADS. ALTHOUGH BOTH THE VULCAN IRON FM. AND THE RIVERTON IRON FM. ARE PRECAMBRIAN X IN AGE, THE VULCAN IRON FM. IS THE OLDER. THE VULCAN IRON FM. IS PART OF THE MENOMINEE GROUP. |
| Deposit | VULCAN IRON FORMATION CONSISTS OF THINLY BEDDED LAYERS OF MAGNETITE, MARTITE, AND SPECULARITE, ALTERNATING WITH QUARTZ-RICH LAYERS; MINOR LOW-IRON SILICATE MINERALS ARE PRESENT (DUTTON AND ZIMMER, 1968). THE FORMATION RANGES FROM 300-800 FT THICK. |
