Abstract Recent models of South Atlantic opening history focus on early plate divergence by
incorporating intracontinental deformation, which is poorly constrained. Aiming to avoid the …

Abstract The South Atlantic region displays (1) a topographic gradient across the basin, with
Africa elevated relative to South America,(2) a bimodal spreading history with fast spreading …

Existing models of relative motion between the South America and Africa plates significantly
misrepresent the azimuth of Lower Cretaceous seafloor spreading in the South Atlantic …

The opening of the Central Atlantic Ocean basin that separated North America from
northwest Africa is well documented and assumed to have started during the Late Jurassic …

The relief of the South Atlantic is characterized by elevated passive continental margins
along southern Africa and eastern Brazil, and by the bathymetric asymmetry of the southern …

We present a revised model for the opening of the South Atlantic Ocean founded on a
remapping of the continent—ocean boundaries and Aptian salt basins, the chronology of …

Subduction zones and their associated slabs are the main drivers of plate tectonics and
mantle flow, but how these zones initiate remains enigmatic. In the Scotia Sea region …

In this paper a new set of finite rotations describing the relative motion of the Pacific and
North America plates during the last 10 my, incorporating recently published studies of the …

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 …

Net relative vertical movements of continental surfaces can be identified and compared on
an intercontinental scale by calculating percentages of flooding on continents at specific …
