The formation of rifted margins involves the deformation of pre-existing lithosphere whose rheological and mechanical behavior during extension is complex since it is the product of numerous earlier tectonic events. In this work we investigate the Campos Rifted Margin (CRM) architecture, with the aim of exploring the role of basement inheritance an...
The origin of the Rio Grande Rise and Walvis Ridge within the central South Atlantic and its implications for the separation of South America and Africa during the Cretaceous are controversial. The recent report of the discovery from submersible sampling of continental material of Proterozoic age on the Rio Grande Rise suggests that the existing ex...
We present a new magnetic map integrating continental and oceanic features at the Santos Basin, in order to investigate the connection between onshore and offshore tectonics and magmatism at the early stages of rifting. The magnetic and seismic data evidence the offshore continuity of the Florianópolis and Serra do Mar dyke swarms, while the Ponta...

Orogenic sutures are mega lineaments that mark the limit between tectonic active plates with different genesis as a result of terranes collage. These zones are characterized by high strain, high grade metamorphism and/or ophiolite complexes. On aeromagnetic maps these sutures are normally well represented by lineaments with high positive anomalies....

The magmatism of the rifted passive margin and adjacent coastal domains in Santos Basin, southeast Brazil, was related to the disassembly of Western Gondwana and the formation of the Atlantic Ocean. The magmatism in Santos is longstanding, encompassing multiple pulses from the Lower Cretaceous to the Paleogene lasting at least 95 Ma. Our research i...
The Santos Basin, in the offshore southeastern Brazilian margin, evolved from a continental rift system to a passive divergent margin during the Cretaceous as a consequence of the Gondwana breakup and the formation of the proto-Atlantic Ocean. The basin exhibits several cycles of magmatism from Valanginian to Eocene times, with a regionalized distr...

Margens continentais passivas são resultantes da interação espaço-temporal de processos tectônicos, sedimentares e termais e se diferenciam, essencialmente, pela herança estrutural, evolução térmica e composição da litosfera. Em especial, os fatores relacionados à herança estrutural exercem grande influência na distribuição e/ou localização da defo...

Deep-water rifted continental margins show diverse architectures which reflect the complexities of local and regional processes controlling their formation. Theory, experiments and observations show that their evolution is influenced by first-order elements like compositional inheritance, temperature and kinematics. Nevertheless, to unravel their i...
The recent report of the discovery from submersible sampling of continental material of Proterozoic age on the Rio Grande Rise suggests that the formation processes of the Rio Grande Rise and Walvis Ridge in the southern S. Atlantic need to be re-examined. Existing proposed formation processes involve ocean ridge – mantle plume interaction or simpl...
