      Red Sea Basin Province as part of a program to assess the recov-erable oil and gas resources of priority basins around the world. The Red Sea Basin Province encompasses the Red Sea, Gulf of Suez, Gulf of Aqaba, and adjacent coastal areas (fig. 1), an area of about . The Gulf of Aqaba is considered as an interesting rift system. Therefore, it is important to understand the crustal features and thickness variation along the Gulf; to be able to evaluate the effect of tectonic activities in shaping the Gulf. The obtained data were used to estimate the reliable empirical relations between the Bouguer anomalies (ΔgB) and crustal thickness (Hc) in the Gulf of.

      1 Introduction. During Late Triassic to Early Jurassic times the Western Tethys was characterized by extensional tectonics related to the westward progression of the Tethys rift system that culminated with the multiphase breakup of Pangea [e.g., Ziegler, ; Dercourt et al., ; Ricou, ].Permian (Zechstein) and Late Triassic (Keuper) evaporites and evaporite‐bearing sediments were. of the tectonic evolution of the Red Sea-Gulf of Aden area. 1. INTRODUCTION Early palaeomagnetic results from the Aden region appeared to be highly consistent with a dilational origin of the Red Sea and Gulf of Aden (Irving & Tarling I96I), and the more recent.

      A modern example of a rift system that has led to the development of continental separation, connation of oce- anic crust, and a divergent plate boundary is the East African Red Sea, Gulf of Aden rift system. Studies in this region have produced good, yet still incomplete, un- derstanding of the evolution of a divergent plate- boundary system. The Danakil Depression lies at the northern end of the Afar region in north Ethiopia; this position marks the triple junction between the Nubian, Somalian, and Arabian plates, as well as the Danakil microplate, which are diverging due to extension in the Red Sea, Gulf of Aden, and East African rifts (Figure 1, e.g., Stab et al., ; Tesfaye.

The work is arranged in eight sections: following a review of the sedimentology and stratigraphy of rift basins, the magmatism and structural evolution of the Red Sea - Gulf of Aden rift is reviewed. Subsequently, new case studies are presented of the early rifting environment, syn-rift sedimentation, tectonics and diagenesis, evaporites and.

Sedimentation and Tectonics in Rift Basins: Red Sea - Gulf of Aden presents new case studies and synthesises the results of recent research on the sedimentological evolution of the Red Sea - Gulf of Aden rift system. This rift basin is generally regarded as the best natural geological laboratory in the world in which to study the processes of rift formation.

The Red Sea is a natural laboratory for continental breakup processes at an embryonic stage whereas the North and South Atlantic oceans correspond to a more developed system of divergent margin basins, in which the tectonic plates in advanced stages of drifting (Mohriak and Leroy, ).Surprisingly, there are only a few works focused on rift architecture and salt tectonics of the Red Sea.

The Gulf of Aden and Red Sea basins tectonically link through Afar ().The geometry of this connection is dramatically illustrated by compilations of seismicity (Fig. 2; e.g., Ambraseys et al.,Hofstetter and Beyth, ).The Red Sea rift initially included the present Gulf of Suez and the Bitter Lakes and Nile Delta region on the continental margin of North Africa (Bosworth and McClay.

Onset of rifting, and flooding by marine waters, occurred in the late Oligocene in the Gulf of Aden and southern Red Sea. The northern part of the Red Sea may have been a largely continental rift at this initial stage, but continued rifting established marine conditions throughout the system.

The seismically and volcanically active East African Rift System is an ideal laboratory for continental break-up processes: it encompasses all stages of rift development. Its northernmost sectors within the Afar volcanic province include failed rifts, nascent sea-floor spreading, and youthful passive continental margins associated with one or.
