Total field magnetic anomaly map of the study area. The evident inverse dipole Pirapora anomaly is highlighted in the central part. Other circular and dipolar magnetic anomalies with normal and reversal magnetizations are present in the APIP area. QF= Quadrilátero Ferrífero; MC: Mata da Corda Formation; Alto do Paranaíba Mafic Alkaline Igneous Province (APIP): SN/AS= Serra Negra/Salitre, Ax= Araxá and TP= Tapira. The data used and enhancement methods applied are better described in item 2 of the Appendix.
