Calcareous Nannofossil Biostratigraphy
Abstrak
A biostratigraphic study of the Upper Cretaceous-Lower Tertiary rocks of Wadi Feiran and Gebel Qabcliat, SW Sinai has allowed the application of several calcareous nannofossil biozones. A Cretaceous/Tertiary nannofloral break is present in the two studied sections and the magnitude of the hiatus is greater to the south, at G. Qabeliat. This boundary occurs somewhere at the top of the Sudr Chalk in the W. Feiran section and in the lowermost part of the Esna Shale in the G. Qabe liat section. No nannofloral break was observed within the Esna Shale at the Paleocene/Eocene boundary in the sections. Introduction The stratigraphy of the Late Cretaceous-Early Tertiary rocks in Sinai has attracted the attention of many authors (e.g. Nakkady, 1949, 1950; Said&Kenawy, 1956; Ghorab, 1961; Abdel Malik, 1967; Abdel Malik et al., 1978a, b; Masters, J 984; Khalil, 1986; Hewaidy, 1987; Abou-El Enein, 1989; Cherif et al., 1989; El-Dawoody, 1992; Ismail, 1992). The objective of this work was to study the calcareous nannoplankton present in the Wadi Feiran and Gebel Qabeliat sections (Figure I) and to provide a biozonation of this area. 33°30'
