Abstract
The Cenomanian - Lower Turonian successions in west-central Sinai are studied at Gabal Essila section, Gabal Musaba Salama section, Gabal Farsh El Ghozlan section and Gabal Mukattab section. The Cenomanian - Lower Turonian successions in the four studied sections were assigned to the following rock units from the oldest to the youngest as follows: Raha Formation (Abu Had Member, Mallaha Sand Member), Abu Qada Formation and The base of Wata Formation. The studied microfacies reveal eight microfacies main types. The micropaleontology includes the foraminifera and ostracodes. The identified foraminifera contains 102 species belonging to 69 genera and 41 families. Out of this content, 86 species belong to benthic foraminifera, and 16 belong to the planktonic ones. The detailed investigation of the ostracod content has led to the recognition of 74 species belonging to 38 genera and 15 families of the suborders Platycopina and Podocopina. The vertical stratigraphic ranges of foraminifera and ostracods have led to the recognition of combined five foraminiferal and three ostracod biozones. The Raha Formation was deposited under intertidal / shallow subtidal environment. The Abu Qada Formation represents the shallow subtidal conditions. The paleobiogeographic distribution of the recorded ostracod and larger benthic foramoniferal are typical of Tethyan carbonate shelf.
