Integrated stratigraphy, palaeontology and facies analysis of the Cenomanian – Turonian (Upper Cretaceous) Galala and Maghra El Hadida formations of the western Wadi Araba, Eastern Desert, Egypt Dissertation zur Erlangung des Naturwissenschaftlichen Doktorgrades der Bayerischen Julius-Maximilans-Universität Würzburg Vorgelegt von EMAD HAMDY MAHMOUD NAGM aus ÄGYPTEN WÜRZBURG, 2009 1 Integrated stratigraphy, palaeontology and facies analysis of the Cenomanian – Turonian (Upper Cretaceous) Galala and Maghra El Hadida formations of the western Wadi Araba, Eastern Desert, Egypt Abstract Four sections of the Galala and Maghra El Hadida formations on the footwalls of the slopes of the northern and southern Galala plateaus in Wadi Araba (Eastern Desert) have been measured and sampled in great detail. The Galala Formation is ranging in thickness from 55 to 95 meters. It unconformably overlies the Malha Formation which forms the base of the studied sections. The upper boundary of the Galala Formation is characterized by a major unconformity which separates it from the overlying the Maghra El Hadida Formation. The Galala Formation can be subdivided into five shallowing-upward cycles, each cycle starting with deep-lagoonal, marly-silty deposits at the base and grading into highly fossiliferous shallow-lagoonal limestones at the top.
