The Quadrilátero Ferrífero (QF) comprises an area of about 7000 km 2 and hosts one of the largest concentrations of lateritic iron-ore deposits in the world. The QF is located in central Minas Gerais state, southeastern region of Brazil (Dorr, 1965).The QF has a quadrangular shape due to the dome and basin structures of the Minas Supergroup (Fig. 1).

Automated recognition of stratigraphic marker shales from geophysical …
The mining of stratiform ore deposits requires a means of determining the location of stratigraphic boundaries. A variety of geophysical logs may provide the required data but, in the case of banded iron formation hosted iron ore deposits in the Hamersley Ranges of Western Australia, only one geophysical log type (natural gamma) is collected for this purpose.
