We present new evidence for the existence of a large pockmark field on the continental slope of the Santos Basin, offshore southeast Brazil. A recent high-resolution multibeam bathymetric survey revealed 984 pockmarks across a smooth seabed at water depths of 300-700 m. Four patterns of pockmark arrays were identified in the data: linear, network, concentric, and radial. Interpretation of Two-d...

Abstract High-resolution bathymetric and shallow seismic data along the northeast Red Sea margin reveal a previously disregarded mechanism for carbonate platform drowning at steep-flanked rift basin. At seafloor, salt extrusions highlight influence of extensional tectonics, with flow from southern flank Al Wajh that likely originates below. Salt-flow direction, morphology, kilometer-sized slump...

Orogens are traditionally classified according to their tectonic style. Paleoproterozoic tectonics is referred as “ancient-style tectonics” while Proterozoic “modern-style tectonics”. Ancient-style characterised by distributed vertical structures and low topography gradients, often associated with diapirism partial melting. In contrast, modern-style involve prominent strain localisation the for...
