“…As noted by various authors, an evolution of RSCM has been episodic with prolonged hiatus around 14−5 Ma BP followed by faster extension (Girdler, 1985;Hempton, 1987, Voggenreiter et al, 1988 (Figure 2). The first stage of extension is commonly dated at the Oligocene, around 28 Ma BP.…”

“…Previous studies on the RSCM mainly focus on its tectonic evolution by geological and geophysical observations and much of its development either by the regional plate stress or mantle plume has been a debatable issue (Mooney et al, 1985;Bohannon, 1986;Hempton, 1987;Pallister, 1987;Voggenreiter et al, 1988;Bohannon and Eittreim, 1991;Makris and Rhim, 1991;Davison et al, 1994).

“…High thermal gradients along the margin form an area for good hydrocarbon potential. RSCM is characterized by occurrences of thin sediments with significant onshore uplift and tectonic subsidence as well as the zone of high seismicity and active faults related to extending lithosphere (Bohannon, 1986;Giraud et al, 1986;Hempton, 1987;Pallister, 1987;Voggenreiter et al, 1988;Bohannon et al, 1989;Davison et al, 1994;Johnson, 1998;Hayashi, 2006, 2007). Several generations of active faults, block faulting and listric normal faults created by the volcanic eruptions strongly suggests regional uplift and tilting (Pallister, 1987;Davison et al, 1994;Kaliwoda et al, 2007).…”

“…Regional stress field or thermal upwelling of the asthenosphere, inherited zones of weakness and the rheological structure of the lithosphere are the factors contributing to the initiation of rifting and deformation of lithosphere (Sengör and Burke, 1978;Turcotte and Emermen, 1983;Voggenreiter et al, 1988;Ziegler and Cloetingh, 2004). The Red Sea rift, which extends from Gulf of Aden and Afar triple junction in the south into Gulf of Suez and Dead Sea transform in the north, is a spectacular example of lithospheric extension (Figure 1).…”

“…Several generations of active faults, block faulting and listric normal faults created by the volcanic eruptions strongly suggests regional uplift and tilting (Pallister, 1987;Davison et al, 1994;Kaliwoda et al, 2007). Off-axis volcanism has been one of the principal lines of evidence for simple shear models of continental rifting (Wernicke, 1985;Bosworth, 1987;Voggenreiter et al, 1988).…”

The Red Sea continental margin (RSCM) corresponds to a wide hinge zone between Red Sea and Arabian plate. This margin has been studied through geological and geophysical observations primarily in regard to the evolution of Red Sea rift. This margin is characterized by occurrence of thin sediments, significant onshore uplift, tectonic subsidence of the offshore sedimentary basin, active faulting and seismicity. Studies indicate that sedimentary sequences of the margin are deformed by faults and folds resulting from at least two phases of extension and a phase of uplift. During the two phases of extension due to regional plate stress the sequence was cut by set of extensional faults. While during the phase of uplift the sequence was deformed by folding and faulting. The present paper aims to clear the structural development of RSCM during these tectonic episodes, taken as particular tectonic event, by two-dimensional finite element modeling on plane strain condition. Elastic rheology is assumed for the oceanic, continental and transitional crust along with syntectonic deposits. Stress field, shear stress and fault distribution suggests that mantle plume weakened the crust following rifting due to regional stress and developed the margin. These results are well consistent with those from present seismicity, active faulting and neotectonic studies.

Numerical time‐temperature models derived from a 2‐D network of apatite and zircon (U‐Th)/He ages reveal a three‐stage thermotectonic history for the central Arabian rift flank (CARF) of the Red Sea Rift (RSR) system. The pre‐rift Arabian‐Nubian Shield existed as part of a passive Paleo‐Tethyan margin until a widespread tectonic event at ~350 Ma exhumed the proto‐CARF to mid‐to‐upper crustal structural levels. After remaining thermally stable through the Mesozoic, the first phase of RSR extension began with a distinct rift pulse at ~23 Ma when fault blocks across a 150 km wide area were exhumed along a diffuse set of rift‐parallel faults from an average pre‐rift flank depth of 1.7 ± 0.8 km. This rift onset age is mirrored in thermochronometric and sequence stratigraphic analyses elsewhere along the Red Sea Nubian and Arabian margins, confirming that rifting occurred concomitantly along the full Red Sea‐Gulf of Suez rift system. Diffuse lithospheric extension lasted for 8 Myr before a second rift pulse at ~15 Ma, coincident with regional stress realignment, transferred active faulting basinward toward the modern RSR axial trough. CARF time‐temperature models indicate that the prevalent rift style during both RSR extensional phases was one of localized, structurally controlled block faulting and contemporaneous dike injection, not wholesale rift flank uplift.
