B. H. Emraninasab et al. 315HST system tracts, separated from each other by MFS. Sartakht formation rocks in Bakhshi section are deposited in a low-angle homoclinal ramp, mostly in the inner ramp, located in the south of Paleotethys Ocean. The depositional sequence identified in Sartakht formation points to the age of middle Permian, conforming to middle Absaroka II supersequence. The upper erosional boundary between Sartakht and Hermez formations conforms to the global-scale sea level fall.

“…The thickest outcrop (120 m) of the Araba Formation occurs at its type locality in the Gabal Araba-Abu Durba area, southwest central Sinai (Said, 1971). Southward of west-central Sinai, at Wadi Feiran, it is only 100 m thick (Allam, 1989;Khalifa et al, 2006). Also, in west central Sinai, in the Um Bogma area, the Araba Formation attains a thickness of about 90e100 m (Kora, 1984).…”

“…In southeast central Sinai, west of Taba, the Araba Formation is 120 m thick. At Gabal El-Zeit on the western side of the Gulf of Suez, the Araba Formation varies in thickness from 35 m to 60 m (Allam, 1988;Wanas, 1997;Khalifa et al, 2006). In the Eastern Desert, north of Wadi Qena, the Araba Formation is 50e60 m thick.…”

“…The Araba Formation non-conformably overlies the undulatory surface of the weathered basement rock (Fig. 5, Wanas, 1997), and the contact is characterized by a kaolinized zone that includes quartz pebbles and gravels of various clast sizes (Khalifa et al, 2006). The upper contact of the Araba Formation exhibits a conformable relationship with the overlying Naqus Formation.…”

Lower Paleozoic rocks are exposed in various regions of Egypt (south central Sinai, north Eastern Desert and southwest Western Desert), in addition to occurring in the subsurface such as north Western Desert and the Gulf of Suez. The Lower Paleozoic rocks in Egypt include surface and subsurface rock units of formational status. The surface rock units are the Taba, Araba and Naqus formations. The subsurface rock units include the Shifa, Kohla and Basur formations.The Infracambrian Taba Formation has been discovered recently in the outcrops of the southeast central Sinai in the Taba-Ras El-Naqab area. It is missing and/or not recognized in the subsurface. The Taba Formation consists mainly of reddish brown, unfossiliferous gravelly fine-to medium-grained kaolinitic sandstones and subordinate horizons of paleosols. The Cambrian Araba Formation and its subsurface equivalent (the Shifa Formation) are essentially composed of reddish brown, fine-grained laminated sandstone and siltstone with abundant Skolithos and Cruziana sp. In contrast, the OrdovicianeSilurian Naqus Formation and its subsurface equivalents (the Kohla Formation and Basur Formation) are mainly composed of white, unfossiliferous, cross-bedded, medium-to coarse-grained sandstones with haphazardly distributed pebbles and cobbles. Sedimentological analysis indicates that the Araba Formation and its subsurface equivalent were deposited in a marginal-marine environment, whereas the Naqus Formation and its subsurface equivalents were laid down in a fluvio-glacial environment.Integrated stratigraphic and sedimentological studies of the Lower Paleozoic rocks permit reconstruction of the paleogeography of Egypt at that time. Egypt has been largely controlled since the Cambrian by the pre-existing structural framework of the pre-Phanerozoic basement rocks inherited from the Late Proterozoic Pan-African event. Additionally, sedimentation processes were controlled during Cambro-Ordovician times by tectonic movements, whereas glacio-eustatic control predominated during the Late OrdovicianeSilurian Period. These studies suggest that most areas of Egypt were exposed lands Production and hosting by Elsevier available at www.sciencedirect.com China University of Geosciences (Beijing) GEOSCIENCE FRONTIERS journal homepage: www.elsevier.com/locate/gsf GEOSCIENCE FRONTIERS 2(4) (2011) 491e507with episodically transgression by epi-continental seas related to the paleo-Tethys.
