New findings in the Eocene stratigraphy of Siwa-El Qara stretch, north western desert, Egypt

Metre-scale cyclicity in Middle Eocene platform carbonates in northern Egypt: Implications for facies development and sequence stratigraphy

“…Said (1990) supposed that the geological history of the Egyptian Paleogene was dominated by tectonic events, which may represent an extension or rejuvenation of the Late Cretaceous tectonism. Moustafa and Khalil (1989) concluded that Egypt was greatly influenced during the Eocene by the Syrian Arc movement, the End Lutetian PyreneaneAtlasic event in addition to the Gulf of Suez rifting initiation which resulted in the displacement of many blocks relatively to each other which gave rise to a complex stratigraphic setting on both sides of the Gulf (Steckler et al, 1988;Issawi, 2002Issawi, , 2005Osman, 2003;Issawi et al, 2009;Sallam et al, 2015a). Schandelmeier et al (1997) have mentioned that during the Lutetian, the Alpine orogeny caused crustal shortening and the inversion of sedimentary basins in NE Africa and on the Arabian platform.…”

“…The interpretation of the observed relative sea level changes in stratigraphic sequences sometimes considers tectonic versus eustatic control (Issawi, 2002(Issawi, , 2005Osman, 2003;Issawi et al, 2009 andSallam et al, 2015a,b). The sequence boundary between Lutetian and underlainYpersian or Palaeocene (not covered in this paper) may be regionally observed, and it is clearly related to folding and deformation (e.g.…”

Architecture and evolution of a tectonically-induced Middle Eocene clastic wedge on the southern Tethyan carbonate shelf, North Eastern Desert, Egypt

“…Age equivalent tectonic activity was described from some areas completely exposed during the Bartonian with development of fluvial deposits at Gabal Ataqa (El Akkad and Abdallah, 1971); episodic interruptions by tectonic instability are clearly figured out in the Middle Eocene of the southern Galala plateau with formation fanglomerates and syn-sedimentary deformation (Abou-Khadrah et al, 1994). Some localities show mild inversion as documented with formation of discontinuities or karst features such as Wadi El Ramiliya (El Azabi, 2006) and Gabal Kehilia in north Eastern Desert (Osman, 2003;Selim, 2011). The tectonic instability is also encountered in SW Palmyride fold in Syria during the Middle Eocene time (Chaimov et al, 1992).…”

Stratigraphy, facies analysis and sequence stratigraphy of the Eocene succession in the Shabrawet area (north Eastern Desert, Egypt): an example for a tectonically influenced inner ramp carbonate platform

“…The age of the Suez Formation is Middle Eocene (Lutetian) according to El-Akkad and Abdallah (op. cit), but Osman (2003) assigned the Early Eocene (Late Ypresian) age to this formation for the presence of O. cf. complanatus Lamarck.…”

“…There are some authors (e.g. Osman 2003;Abu El-Ghar 2007;Issawi et al 2009) who believed in the presence of Lower, Middle and Upper Eocene rocks in the north Eastern Desert in general and in the Shabrawet area in particular, whereas others (e.g. Sadek 1926;El-Akkad and Abdallah 1971;Al-Ahwani 1982;Shamah and Helal 1993a, b;Haggag 2010) believed that only Middle Eocene rocks are exposed in the Cairo-Suez district including the study area.…”
