“…During Aptian times, intracontinental siliciclastic sedimentation occurred in fluvial to lacustrine environments all along these two transform faults, in strongly subsiding basins controlled by strike-slip or transtensional faults (Zalan et al, 1985;de Caprona, 1992;Chierici, 1996;Mascle et al, 1996Mascle et al, , 1998Basile et al, 1998;Attoh et al, 2004) (Figs. 3, 4b, d and e).…”

The Phanerozoic geological evolution of the Equatorial Atlantic domain has been controlled since the end of Early Cretaceous by the Romanche and Saint Paul transform faults. These faults did not follow the PanAfrican shear zones, but were surimposed on Palaeozoic basins. From Neocomian to Barremian, the Central Atlantic rift propagated southward in Cassiporé and Marajó basins, and the South Atlantic rift propagated northward in Potiguar and Benue basins. During Aptian times, the Equatorial Atlantic transform domain appeared as a transfer zone between the northward propagating tip of South Atlantic and the Central Atlantic. Between the transform faults, oceanic accretion started during Late Aptian in small divergent segments, from south to north: Benin-Mundaú, deep Ivorian basin-Barreirinhas, Liberia-Cassiporé. From Late Aptian to Late Albian, the Togo-Ghana-Ceará basins appeared along the Romanche transform fault, and Côte dÍvoire-Parà-Maranhão basins along Saint Paul transform fault. They were rapidly subsiding in intra-continental settings. During Late Cretaceous, these basins became active transform continental margins, and passive margins since Santonian times. In the same time, the continental edge uplifted leading either to important erosion on the shelf or to marginal ridges parallel to the transform faults in deeper settings

“…The absence of the Cenomanian-Turonian interval at Site 959, which includes the generally more widespread OAE-2 (Oceanic Anoxic Event; Jenkyns, 1980) and is often represented by black shales, which may be potentially important petroleum source rocks, appears to be a result of submarine erosion and non-deposition associated with the uplift and tilting of the Marginal Ridge in association with the separation of Africa and South America (Basile et al, 1998).…”

“…For example, individual structural elements of the Romanche margin include marginal ridge, platform areas, pull-apart regions, dominating transform segments and subordinate rift margin and oblique rift margin segments (Mascle & Blarez 1987;Mascle et al 1988;Basile et al 1993Basile et al , 1998Peirce et al 1996;Edwards et al 1997;Benkhelil et al 1998;Sage et al 2000;Antobreh et al 2009). The width of the entire fault pattern associated with the Romanche transform fault zone varies between 40 and 70 km depending on area Benkhelil et al 1998;Nemčok et al 2012b).…”

This paper provides an overview of the existing knowledge of transform margins including their dynamic development, kinematic development, structural architecture and thermal regime, together with the factors controlling these. This systematic knowledge is used for describing predictive models of various petroleum system concept elements such as source rock, seal rock and reservoir rock distribution, expulsion timing, trapping style and timing, and migration patterns. The paper then introduces individual contributions to this volume and their focus.
