2018-09-26 07:07:32 Keywords Pliocene, sequence stratigraph, Neogene, carbonates, Cycles, ,
Cyclicity and sequence stratigraphy of syn-rift Late Neogene mixed carbonates-siliciclastics of the area between  Wadi Zug El Bohar and Wadi Dabr, Red Sea, Egypt.
THE LATE OLIGOCENE SEDIMENTS ARE REPRESENTED BY MIXED SILLICICLASTICS AND CARBONATES DEPOSITED UNDER CYCLICAL DEPOSITIONAL CONDITIONS. BASED ON SIZE VARIATIONS AND MIXING OF FACIES, SIX DIFFERENT TYPES OF CYCLES ARE RECOGNIZED; FINING-UPWARD CYCLES, COARSENING-UPWARD CYCLES, MIXED FLUVIAL-LACUSTRINE CARBONATE CYCLES, MIXED FLUVIAL-RESTRICTED MARINE CARBONATE CYCLES, MIXED SILICICLASTIC-OPEN MARINE CARBONATE CYCLES AND DOMINANTLY OPEN MARINE CARBONATE CYCLES. THE DEVELOPMENT OF CYCLIC SEDIMENTATION ... Read more

Mixed Late Oligocene-Middle Miocene siliciclastics-carbonates sedimentation in block-faulted regions: A Model from Wadi Wizr-Wadi Assal area, Red Sea coastal zone, Egypt
The Late Oligocene- Middle Miocene rift sediments in Wadi Wizr-Wadi Assal area south of Quseir could be subdivided into four lithofacies: Facies A : Dominantly alluvial, coarse clastic, fans (Lower part of Ranga Formation). Facies B: Fluviatile coarse and fine siliciclastics, with marine evaporites near the top (upper part of Ranga Formation). Facies C: Open marine, mixed coralgal carbonate-siliciclastic sediments ...
