... (Cruzeiro do Sul lineament) that extends from the Cabo Frio High towards the Rio Grande Rise, thus involving both continental and oceanic crusts. The Rio Grande Rise is associated with the east–west-trending fracture zones, which are characterized by several aligned magnetic anomalies in the southern Santos...

... volcanic features along the NW–SE-trending Cruzeiro do Sul Lineament from Cabo Frio to the Rio Grande Rise, but they have not been dated. The only known occurrence of serpentinized mantle rocks in the South Atlantic margin is associated with the Saint Peter and Saint Paul Rocks located along the São Paulo...

Santos Basin location map. The main tectonic features that limit the basin and the aborted spreading axis (ASA) are shown overlaying the bathymetric map. Modified from Gamboa et al. (2021) and Brazilian Petroleum Agency (ANP) files. The locations of the seismic sections in Figures 4, 5, 7, and 14 are shown. COB = continent–ocean boundary; CSL = Cruzeiro do Sul Lineament intersecting the exploratory blocks; FFZ = Florianópolis fracture zone; RJFZ = Rio de Janeiro fracture zone.

Regional topobathymetric map with main geomorphological features on the eastern Brazilian margin. The Abrolhos Volcanic Complex is characterized by the largest expansion of the platform in SE Brazil, and is limited to the south by the Vitória-Trindade Ridge. The Rio Grande Rise is separated from the southern Santos Basin by the Florianópolis Fracture Zone and the Vema Channel.

Although the Pernambuco Plateau is flanked by prominent basement highs (presumably partly related to oceanic fracture zones), both it and the Rio Grande do Norte Plateau overlie stretched continental crust. In contrast, the Ceará Plateau...
