Abstract
At the end of the Late Eocene there must have been general rise of land causing a northward shift of the shorline of the Mediterranean Geosyncline upto the letitude of the Payoum Province and this ection continued during the Oligocene Period , where the shor- line receded farther north . This explains the alnost continental feotes characteristic to the Oligocene deposits in Egypt . However , in the Fayoun Province fluviatile sands and gravels overlie conformably the Upper Eocene beds , contrasting in this respect the presence of an angular unconformity in the northern pert of the Western Desert « The surface Oligocene sediments of Egypt are mainly composed of continental facies and volcanic flow occupying about usually unconformably overlying the Eocene strata covering the area between Bahariya and Fayoum in the Western Desert . Along the Nile valley , the Oligocene strata appear to the east of Pashn and Beni Suef . They are also recorded throughout the Cairo-Suez district represented by gravels Sands and sandstones devoid of fossils except for silicified wood fragments . In Sinai , the Oligocene sands are exposed over the Tanka beds and east of Sudr on the eastern
