NEW FINDINGS IN THE EOCENE STRATIGRAPHY OF GEBEL ATAQA - NORTHERN GALALA, NORTH EASTERN DESERT, EGYPT. RIFAAT A. OSMAN Banha University The study of three sections in the northwest side of the Gulf of Suez, at Ataqa. North Galala and Kehilia reveals a Lower Eocene Ypresian unit in the former two localities. A Lutetian section was deposited on top of the North Galala, before a major fault brought down both the Ataqa and Kehilia areas against the high North Galala. The Bartonian sea transgressed over the faulted down block i.e. Ataqa-Kehilia, depositing 350m carbonates including Somalina stefanini but North Galala was high; a faulted up block, hence never received Bartonian sediments. The faulting movement echoed the end Lutetian Pyrenean Atlasic stresses related to the collision between Africa and Europe plates.
