摘要

Stratigraphical studies of Miocene exposures on the eastern side of the Gulf of Suez (Wadi Gharandal, Wadi Baba and Wadi Feiran) reveals conspicuous vertical and lateral facies variations due to syngenetic tectonic activity related to rifting. Studied samples include 88 species of foraminifera (39 planktonics and 49 benthonics). Six planktonic biozones (M2-M7) were distinguished. The sequence statigraphical investigation of the Burdigalian to Serravallian succession reveals six thirdorder depositional sequences, bounded by physical unconformity surfaces reflecting phases of subaerial exposure, deposition of alluvial fans, polymictic conglomerates, evaporites and the presence of a faunal break, which could be correlated within and outside Egypt. These sequence boundaries are primarily related to regional tectonism associated with rifting or related to eustatic sea-level fluctuations.
