Volcanism in the Paranabasin, one of the largest continental flood basalt provinces on Earth, was contemporaneous with the Early Cretaceous opening of the South Atlantic Ocean. Problematic is the lack of crustal extension associated with this flood basalt event, although three Palaeozoic-Jurassic extensional episodes have been reported in parts of the basin. Gravity measurements at 185 new stations were established to constrain the geometry and magnitude of Bouguer anomalies that characterise… CONTINUE READING
