Gravity models are powerful tools for map** tectonic structures, especially in the deep
ocean basins where the topography remains unmapped by ships or is buried by thick …

The Brazilian continental margin includes several volcanic islands, submerged volcanic
seamounts, and a unique non-volcanic archipelago located in a transform segment of the …

Abstract The Rio Grande Rise is an extensive seamount region in the South-western
Atlantic, with potential for deep-sea mining activities in the future. Such activities pose …

The South Atlantic rift basin evolved as a branch of a large Jurassic–Cretaceous intraplate
rift zone between the African and South American plates during the final break-up of western …

Abstract The Pelotas Basin is the classical example of a volcanic passive margin displaying
large wedges of seaward-dip** reflectors (SDR). The SDR fill entirely its rifts throughout …

Cretaceous aged salt and salt-free basins along the continental margins of Brazil and
Angola/Namibia exhibit a rather heterogeneous geometry and basin fill which implies a …

Continental microplates are enigmatic plate boundary features, which can occur in
extensional and compressional regimes. Here we focus on microplate formation and their …

The absence of expressive hydrocarbon columns and high CO 2 content observed in the pre-
salt of Santos Basin reservoirs over the last decade reveal the risk of hydrocarbon charge …

Abstract The track of South Atlantic hotspots on oceanic crust is well known. However, the
possible hotspot trails of Tristan-Gough (TG) and St. Helena (SH) plume heads on …

The structure and nature of the crust underlying the Santos Basin‐São Paulo Plateau
System (SSPS), in the SE Brazilian margin, are discussed based on five wide‐angle seismic …
