Comments on the geologic information

  • THE HIGH-GRADE HEMATITE ORE INCLUDES COMPACT, SOFT AND POWDERY ORES CONTAINING MORE THAN 64 PERCENT IRON. IT OCCURS ALMOST EXCLUSIVELY IN THE CAUE FORMATION OF THE ITABIRA GROUP IN THE MINAS SERIES. THE ORE FORMS SEPARATE BODIES IN THE ITABIRITE, CONSTITUTING POCKETS OR LENSES OF VARIABLE DIMENSION AND VOLUME. ITABIRITE THE NAME GIVEN TO THE BANDED ROCKS IS TYPICAL OF THE MINAS SERIES, COMPOSED OF ALTERNATE LAYERS OF HEMATITE AND QUARTZ WITH AN IRON CONTENT VARYING BETWEEN 35 AND 60 PERCENT. IN SOME AREAS, THE ITABIRITES CONTAIN DOLOMITE OR OTHER MINERALS INSTEAD OF QUARTZ. ITABIRITES ARE THE HOST ROCK FOR THE HIGH-GRADE HEMATITE DEPOSITS OF THE MINAS SERIES.
