Abstract

ISMAIL 2000; OSMAN et al. 2000; BAUER et al. 2002; DAKRORY 2002; EWEDA 2002 and ZALAT 2003). In the Sinai, facies of the Upper Cretaceous are very heterogeneous. They vary from open-marine and relatively deep-water limestone and chalk predominating in the northern part to an altemation of limestones, shales and sandstones in the central part and to shallow-marine sandstones in the southernmost outcrops. In contrast, the Lower Paleogene is much more uniformly developed and is similar to the succession observed in the rest of Egypt. For this reason, the lithostratigraphic nomenclature of the Upper Cretaceous rocks units is rather complex, whereas the lithostratigraphic subdivision of the Paleogene is uniform. The main purpose of the present work is to study the lithostratigraphy, microfacies characteristics and environments of deposition of the Maastrichtian -Paleocene succession exposed in Gabal Ras Al-Giffa and Gabal Bir Umm Said in the west-central Sinai (see Fig. 1, Long. 33° 40’ to 32° 90’ and
