Uma Anomalia Magnetica De Carater Regional No Serido (Rn-Pb) E Uma Discussăo De Sua Origem

The Borborema shear zone system, NE Brazil

“…If the shear zone transected the SeridB belt, the quartzite would be disrupted and an offset of the quartzite would occur; this is clearly not the case. A structural continuity is also suggested by the progressive curvature of the aeromagnetic anomalies (Moreira et al, 1989) that follow the rotation of the tectonic fabric without any discontinuity (Fig. 19).…”
