Magma-rich rifting generally occurs over mantle plumes or rising convection cells; magma-
poor rifting does not. Plumes produce up to 2 km dynamic elevation, outcompeting synrift …

The crustal structure of the Equatorial Atlantic conjugate margins (South America and West
Africa) has been investigated using 3D gravity anomaly inversion, which allows for (1) the …

Abstract The Aptian Pre-Salt sedimentary succession crop** out in Cangulo palaeovalley
onshore Namibe Basin (Angola) was studied by a combination of field and analytical …

Volcanic plumbing systems emplaced in sedimentary basins may exert significant
mechanical and thermal effects on petroleum systems. The last decade of research has …

Magmatic activity can severely alter the thermal structure of a sedimentary basin, with
variable effects on the petroleum system. The Namibe Basin of Angola (Cretaceous South …

Outer marginal collapse (OMC), a recently proposed process by which top-rift and base-salt
unconformities formed near sea level may subside rapidly to 2.5–3 km at continental …

Abstract The Namibe Basin developed in the Early Cretaceous as part of the South Atlantic
rift system between Africa and South America. Magmatic activity occurred during the syn-rift …

Abstract The Mesozoic Gulf of Mexico Basin is considered in this discussion as the set of
contiguous, Triassic and Jurassic sub-basins directly involved in the counterclockwise …

A aquisição e interpretação de novos dados sísmicos tem possibilitado melhor visualização
das porções mais profundas de margens passivas, permitindo melhor imageamento e …

We cannot hope to predict Mesozoic depositional processes and sediment properties well
enough to plan effective regional exploration strategies without considering the big picture of …
