Abstract The Miocene succession exposed in the area between Wadi Sudr and Wadi Wardan has been investigated in terms of its sedimentary facies and Faunal characteristics. The tectonic activities and sea level change that prevailed during the Miocene configured its sedimentary sequences. The early Miocene starts with the deposition of algal limestone of the Somar Member that changed later into fan-conglomeratic facies under the effect of the Early-Clysmic tectonic event. Basinward, facies migrated into wave-dominated clastic unit of the Asl Member. Sea level rise would be responsible for the deposition of shelf facies of the Upper part of the Rudeis Formation (Upper Rudeis Member). Sealevel DROPs, accompanied by secondary tectonic uplift, resulted in the deposition and differentiation of the shallow evaporitic facies of the Kareem Formation that developed with time into marginal marine to fluvial thin clastic sequence of the Belayim Formation. Post-Belayim Formations (South Gharib and Zeit) are laid in lagoonal environments and form low land terraces. |
