Segmentation and differential post-rift uplift at the Angola margin as recorded by the transform-rifted Benguela and oblique-to-orthogonal-rifted Kwanza basins

Rifting, subsidence and continental break-up above a mantle plume in the central South Atlantic

“…It correlates approximately with the base of the inferred basalts on the high signifying the onset of sea-floor spreading (Fig. 7) (Jackson et al 2000;Winter et al 2007 Guiraud et al 2010), marking the end of continental rifting and start of oceanic spreading. Such tectonic events are often associated with erosion (e.g.…”

“…Instead, it is parallel-layered -passively infilling and draping the angular unconformity (Fig. 6b), similar to early post-rift strata in basins throughout the world (Nøttvedt et al 1995;Guiraud et al 2010). Maximum relief at the base of the interval is around 500 m compared to the top (Fig.…”

Post-Gondwana Africa and the vertebrate history of the Angolan Atlantic Coast

“…Africa's drift can be followed especially well because conjugate basins shared between Africa and South America provide fixed starting points (Brownfield and Charpentier, 2006), and because of seafloor magnetic stripes (Cande et al, 1989;Müller et al, 1997;He et al, 2008), hot spot traces (O'Connor and le Roex, 1992;O'Connor et al, 1999), predicted paleolatitudes determined from igneous rocks (Strganac et al, 2014a), and fault zones that can be followed from the Mid-Atlantic Ridge to the coast of Africa ( fig. 4) (Eagles, 2007;Guiraud et al, 2010).…”

“…6). Most of these sites are in coastal basins along the continental margin with sedimentation controlled by eustatic sea level (Müller et al, 2008) in conjunction with structural motions ascribed to salt tectonics and movements along preexisting faults (Brognon and Verrier, 1966;Cauxeiro et al, 2014;Ciampo et al, 2001;Guiraud et al, 2010;Hudec and Jackson, 2002;Jackson and Hudec, 2005).…”

From orogen to rifted passive margin formation in Brazil: Geodynamic numerical modeling considering the effects of structural inheritance and rheology

“…Onshore geology was interpreted after geological type cross sections of (Tack et al, 2001) and offshore crustal structure was interpreted after seismic sections of Blaich et al (2011), structural maps by Guiraud et al (2010), regional transect made by Hudec and Jackson (2004) and gravimetric modelling by von Nicolai et al (2013).
