| Abstract | ||||
| The early and middle Eocene successions of Wadi EL Qena (Sec. II) and Wadi El Agramiya (Sec. I) surface sections in west El Galala El-Baharia area, north Eastern Desert, were examined in detail. Their planktonic foraminifera and microfacies associations were used to interpret the stratigraphy of these sections. A total of twenty species and subspecies of planktonic foraminifera belonging to eight genera as well as six microfacies associations were also identified and their stratigraphic ranges were given. The succession was divided into distinct litho and biostratigraphic units. The distribution of foraminifera allows the subdivision of studied sections into three foraminiferal zones from the base upwards as: Acarinina pentacamerata zone, Nummulites gizehensis zone and Dictyoconus Egyptians's zone related mostly to early and middle Eocene age, Besides, microfacies studies on thin sections representing Minia Formation, Gabal Hof Formation and Observatory formation were carried out. The paleoenvironmental conditions that prevailed during sedimentation were interpreted in accordance. | ||||
