“…Deposition during the Aquitanian was controlled by short-segmented, closely spaced faults (e.g., Gawthrope et al, 1997;Winn et al, 2001), and the rate of rotation of fault blocks peaked at this time . The Abu Zenima-Nukhul section includes chert-cobble conglomerate, channelized sandstone, marine shale, a variety of carbonate facies, and anhydrite (EGPC, 1964;Saoudi and Khalil, 1986) and attains a maximum thickness of $500 m. In northern Saudi Arabia, Chattian age ($28.4-23.0 Ma) early rift deposits were described from Midyan (Dullo et al, 1983;Bayer et al, 1988;Purser and Hö tzl, 1988), but their microfaunas have been re-interpreted as Aquitanian (Hughes et al, 1999). Several species of reworked Chattian foraminifera were also reported from Aquitanian Globigerina marls in a 5 m core at the base of a well at Hurghada Field in the southern Gulf of Suez (ElShinnawi, 1975).…”

“…Micropaleontological studies of exploratory wells and some outcrops have suggested that the oldest syn-rift formations, exclusive of the very southern Red Sea, are ϳ23 Ma, near the Oligocene-Miocene boundary (Bunter and Abdel Magid 1989;Hughes and Beydoun 1992;McClay et al 1998;Bosworth et al 1998;Hughes et al 1999). Other interpretations have placed the base syn-rift unconformity within the Late Oligocene (Dullo et al 1983;Bayer et al 1988;Purser and Hötzl 1988;El Barkooky and El-Araby 1999;Bosworth and McClay 2001;Jackson et al 2006;Jackson 2008), or even Early Oligocene (Hughes and Filatoff 1995;Koeshidayatullah et al 2016).…”

Throughout the greater Red Sea rift system the initial late Cenozoic syn-rift strata and extensional faulting are closely associated with alkali basaltic volcanism. Older stratigraphic units are either pre-rift or deposited during pre-rupture mechanical weakening of the lithosphere. The East African superplume appeared in northeast Africa ϳ46 Ma but was not accompanied by any significant extensional faulting. Continental rifting began in the eastern and central Gulf of Aden at ϳ31-30 Ma coeval with the onset of continental flood volcanism in northern Ethiopia, Eritrea, and western Yemen. Volcanism appeared soon after at Derudeb in southern Sudan and at Harrats Hadan and As Sirat in Saudi Arabia. From ϳ26.5 to 25 Ma a new phase of volcanism began with the intrusion of a dike field reaching southeast of Afar into the Ogaden. At 24-23 Ma dikes were emplaced nearly simultaneously north of Afar and reached over 2000 km into northern Egypt. The dike event linked Afar to the smaller Cairo mini-plume and corresponds to initiation of lithospheric extension and rupture in the central and northern Red Sea and Gulf of Suez. By ϳ21 Ma the dike intrusions along the entire length of the Red Sea were completed. Each episodic enlargement of the greater Red Sea rift system was triggered and facilitated by breakthrough of mantle-derived plumes. However, the absence of any volumetrically significant rift-related volcanism during the main phase of Miocene central and northern Red Sea -Gulf of Suez rifting supports the interpretation that plate-boundary forces likely drove overall separation of Arabia from Africa.Résumé : Dans l'ensemble du grand système du rift de la mer Rouge, les strates initiales syn-rifting et l'extension par failles d'âge cénozoïque tardif sont étroitement associées à un volcanisme basaltique alcalin. Les unités stratigraphiques plus anciennes précèdent la formation du rift ou ont été déposées durant l'affaiblissement mécanique de la lithosphère qui a précédé la rupture. Le superpanache est-africain est apparu dans le nord-est de l'Afrique à ϳ46 Ma, mais n'était pas accompagné d'une importante déformation par failles. Le rifting continental a commencé dans l'est et le centre du golfe d'Aden à ϳ31-30 Ma, en même temps que le début du volcanisme continental de plateau dans le nord de l'Éthiopie, en Érythrée et dans l'ouest du Yémen. Le volcanisme est apparu peu après à Derudeb, dans le sud du Soudan, et aux Harrats Hadan et As Sirat, en Arabie saoudite. À partir de ϳ26,5-25 Ma, une nouvelle phase de volcanisme a débuté avec l'intrusion d'un essaim de dykes allant du sud-est d'Afar jusque dans l'Ogaden. À 24-23 Ma, des dykes ont été mis en place presque simultanément au nord d'Afar et s'étalant sur plus de 2000 km jusque dans le nord de l'Égypte. L'intrusion de dykes a relié Afar au mini-panache plus petit du Caire et correspond au début de la distension et de la rupture lithosphériques dans le centre et le nord de la mer Rouge et le golfe de Suez. À ϳ21 Ma, l'intrusion de dykes sur toute la longueur de ...

“…Large-scale slump structures in the evaporites of the Magna Formation can easily be observed in almost every part of the outcrop. The thickness of the formation ranges from 150 m thick at the outcrop (Motti et al, 1982) and 300 m in exploration wells drilled in the Red Sea and offshore Midyan Peninsula (Dullo et al, 1983). Based on the presence of age-diagnostic planktonic foraminifera and calcareous nannofossils collected from the surface and subsurface samples of the Magna Group, it was dated as Early to Middle Miocene (Hughes and Filatoff, 1995).…”

The hydrocarbon-producing Midyan Basin is located in northwestern Saudi Arabia and is surrounded by the Proterozoic igneous basement of the Arabian Shield. It includes thick hydrocarbon-producing sedimentary sequences deposited in half-grabens that formed during rifting of the Red Sea and the gulfs of Suez and Aqaba in the Early Miocene (23.3 Ma). The early syn-rift succession consists of arid alluvial fan sediments and playa evaporates, followed by shallow marine carbonates. The late syn-rift sequences consist of progradational deep sea turbidites and Alpine-type glacial deposits indicating strong vertical uplift during the climax of the rifting (19 Ma). The post-rift succession overlies the late syn-rift successions and consist of shallow marine marls and evaporites. The aim of this study is to examine the hydrocarbon potential of the turbidite sandstones and the formation of various types of glacial deposits in the Burqan Formation. This study also encompasses the importance of various geologic processes in order to understand their significant influence on the geometry, continuity and reservoir quality of oil and gas producing genetically different sandstones in the subsurface of the Burqan Formation in the Midyan Basin. The Alpine-type glacial deposits provide an excellent opportunity to study the presence of continuous vertical and lateral facies variations between true glacial, glacio-fluvial and glacio-marine deposits in the direction of sediment transportation. Unsorted moraines deposited in the deep and U-shaped glacial valleys occupy the northwestern part of the basin. They pass gradually into glacio-fluvial sandstones that contain large polished and striated boulders. In the southeastern part of the deep basin, the glacio-marine deposits are associated with deep sea turbidites and pelagic shales. Many stratigraphic and sedimentologic sections were measured from well-exposed outcrops in every part of the basin to establish various depositional environments. A large number of sandstone samples was collected to examine their reservoir quality.
