Rift basin exploration has provided the oil and gas industry with almost one third of discovered global hydrocarbon resources. The maturity of prolific passive margin sequence plays has necessitated a shift in technical emphasis to understanding petroleum geology of the deeper precursor rift basin megasequences. Modelling of these petroleum systems relies extensively on theoretical stretching hypotheses for whole-crust evolution and heat flow prediction. Several alternatives have emerged to…

Geodynamics of the central South Atlantic conjugate margins: implications for hydrocarbon potential
ABSTRACT Using a new margin restoration model for the central South Atlantic we highlight margin-opposed rift basin subsidence characteristics, reconcile important facies relationships and consider
Depth-dependent extension, two-stage breakup and cratonic underplating at rifted margins
TLDR
Dynamical models demonstrate that in type I, depth-dependent extension results in crustal-necking breakup before mantle-lithosphere breakup and in type II, the converse is true; these two-layer, two-stage breakup behaviours explain the discrepancies and have implications for the styles of the associated sedimentary basins.
The boundary between continental rifting and sea-floor spreading in the Woodlark Basin, Papua New Guinea
Abstract Seismic reflection, bathymetry, acoustic imagery and magnetic data are presented that encompass the boundary between rifting of the Papuan continent and westward propagating sea-floor
Constraints on the deformation and rupturing of continental lithosphere of the Red Sea: the transition from rifting to drifting
Abstract The Red Sea is an ideal locale for testing differing models and hypotheses for rift evolution and the initiation of sea-floor spreading. The Red Sea is an active rift system that formed by
Facies analysis and depositional environments of the Miocene syn-rift carbonate–siliciclastic rock packages in the northwest Gulf of Suez, Egypt
The Miocene sedimentary successions in the northwest Gulf of Suez allow insight into the syn-rift deposition. These rocks are subdivided into three formations, namely the Sadat Formation coeval with

Evolution of magma-poor continental margins from rifting to seafloor spreading
TLDR
It is concluded that the evolving stress and thermal fields are constrained by a rising and narrowing ridge of asthenospheric mantle, and that magmatism and rates of extension systematically increase oceanward.
Syn-rift regional subsidence across the West African continental margin: the role of lower plate ductile extension
Abstract New ostracode data from the West African margin indicate that the Outer Basin Sediment Wedge (also termed the ‘pre-salt wedge’ and the ‘pre-salt sag basin’) is Neocomian to Aptian in age and
Abstract: New Insights into South Atlantic Rifting from the Santos and Campos Basins, Offshore Brazil — A Tale of Two Basins
The Santos and Campos basins, offshore Brazil, resulted from the Early Cretaceous break-up of Gondwanaland. South Atlantic margin plate reconstruction models propose uniform east-west extension;
A mechanism to thin the continental lithosphere at magma-poor margins
TLDR
It is shown that crustal thinning can be accomplished in extensional environments by a system of conjugate concave downward faults instead of multiple normal faults, and suggested that the observed transition from broadly distributed and symmetric extension to localized and asymmetric rifting is directly controlled by the existence of a strong gabbroic lower crust.
Lower crustal extension across the Northern Carnarvon basin, Australia: Evidence for an eastward dipping detachment
Asymmetry and strain partitioning along conjugate margins are often explained in terms of detachment faults. Nevertheless, cogent evidence for their existence remains limited. Furthermore, even when
Detachment models for the formation of passive continental margins
The inherent asymmetry of extension by detachment leads to contrasting and conjugate classes of passive margins. Upper-plate margins comprise crust above a deeper detachment. Lower-plate margins

Timing of depth‐dependent lithosphere stretching on the S. Lofoten rifted margin offshore mid‐Norway: pre‐breakup or post‐breakup?
Depth‐dependent stretching, in which whole‐crustal and whole‐lithosphere extension is significantly greater than upper‐crustal extension, has been observed at both non‐volcanic and volcanic rifted
