Deposit Type

  • Banded iron formation


Summary:

The Andrade deposit is located in the north-eastern portion of the Iron Quadrangle. The base stratigraphic section consists of quartzites and sericite-quartzites of the Moeda formation, followed by schists of the Batatal formation, both forming the Caraça group. The iron rich mineral bodies are part of the overlying Cauê formation, which represents the base of the Itabira Group. The Caraça and Itabira groups compose the base of the Paleoproterozoic Minas Supergroup. The Cauê formation rocks are covered by dolomites and marbles, and sometimes weathered phylites and schists, belonging to the Gandarela formation. The deposit is located in the Iron Ore Quadrangle and it is classified by Banded Iron Formation. The Andrade mine is on the northeast flank of the Pico do Andrade 8 kilometers northwest of Monlevade. This mine is linked to the Usina Monlevade by a 10-kilometer meter-gage electrified railroad. The Andrade deposit is on the Fazenda de Andrade, which along with several smaller fazendas was acquired by CSBM in 1921. The ore occurs in the troughs of the syncline and for more than 1,000 meters along the east flank. The ore body as it crops out or is exposed in the opencut mining operations is arcuate, concave to the northeast. The distribution of the various types of ore and itabirite is highly irregular, and it was not feasible to map them separately. Not uncommonly, alternations of equigranular and schistose material occur in bands, lenses, and irregular forms from a f ........
