Traditionally active rifts are thought to evolve in response to thermal upwelling of the
asthenosphere, whereas passive rifts develop in response to lithospheric extension driven …

Abstract The East Brazilian Rift system (Ebris) constitutes the northern segment of the South
Atlantic rift system which developed during the Mesozoic breakup of South America and …

This unique book presents an overview of isostasy, a phenomenon of fundamental
importance to the earth sciences. Isostasy is a simple concept, yet it has long perplexed …

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 …

Abstract The South Atlantic Ocean evolved after rupture of the São Francisco–Congo–Rio
de la Plata–Kalahari cratonic landmass and the Late Proterozoic fold belts. Break-up in the …

We make the case for Early Cretaceous transfer zones that segment the obliquely rifted
Atlantic margin of southeastern Brazil. Our interpretation is based on published literature …

We interpret and document Late Cretaceous and Cenozoic reactivation of older structures
on the obliquely rifted margin of southeastern Brazil, attributing them to the combined effects …

Portions of seismic lines and a structure-contour map illustrate the patterns and shapes of
salt diapirs and related structures in the Campos and Santos areas, off the Atlantic coast of …

The thinning of passive continental margins is usually explained by models using pure
stretching or simple shear. These models imply hypothetical extensional structures and …

The Early Cretaceous South Atlantic continental break-up and initial sea-floor spreading
were accompanied by large-scale, transient volcanism emplacing the Paraná-Etendeka …
