Facies architecture And Sequence Stratigraphy of Early Syn-Rift Siliciclastic Deposits In Hamadat Half graben Basin, South Quseir, Red Sea, Egypt

Facies architecture And Sequence Stratigraphy of Early Syn-Rift Siliciclastic Deposits In Hamadat Half graben Basin, South Quseir, Red Sea, Egypt
Tectono-stratigraphic analysis of Early Syn-Rift Siliciclastic Deposits of Nakheil and Ranga Formations, based on outcrop data from Hamadat Half Graben basin, south Quseir indicates that the evolution of normal faulting was an important role on syn rift depositional patterns and sequence stratigraphic development. The Nakheil Formation was deposited in depocentres formed during the low subsidence rift initiation phase. The Nakheil ... Read more

Geomorphic evolution and karst landforms of the Eocene limestone plateau , west of the Nile Valley (Sohag), Egypt: implications for geohazards and impacts

Geomorphic evolution and karst landforms of the Eocene limestone plateau , west of the Nile Valley (Sohag), Egypt: implications for geohazards and impacts
Most of the limestones in the Eocene Carbonate plateau, west of the Nile Valley (Sohag), are affected repeatedly by karst processes, and different landforms related to limestone dissolution occurred. However, there is no published literature available dealing with the detailed studies of the karstification process and associated karst landforms in this study area. Therefore, this study focuses on paleoerosion surfaces ... Read more

Normal faulting control on the stratigraphiy of the Early Syn Rift synrift lacustrine/shallow marine sequences, south Quseir, Red Sea, Egypt

2018-09-30 08:29:20 | Keywords normal faulting, synsedimentary, lacustrine, Half grabens,
Normal faulting control on the stratigraphiy of the Early Syn Rift synrift lacustrine/shallow marine sequences, south Quseir, Red Sea, Egypt
Tectono-stratigraphic analysis of Late Oligocene-Early Miocene Nakheil and Ranga Formations, based on outcrop data from Hamadat and Zug El Bohar half-graben basins, south Quseir, indicates that the evolution of normal fault segments was an important control on syn-rift depositional patterns and sequence stratigraphic development. Sedimentological and stratigraphic analysis of the Nakheil Formation indicates that it was deposited in a series ... Read more

Facies changes and tectonic-climatic controls on the development of Late Oligocene-Miocene sediments (Pre-Eonile and Eonile phases) of the Egyptian Nile west of Sohag

Facies changes and tectonic-climatic controls on the development of Late Oligocene-Miocene sediments (Pre-Eonile and Eonile phases) of the Egyptian Nile west of Sohag
The geological mapping, landstat images, and detailed sedimentological analysis through measurements of 10 stratigraphic columnar sections, have revealed the presence of four facies associations among the Pre-Eonile and Eonile sediments along the Egyptian Nile west of Sohag. These reflect the co-effect of local and regional tectonics, changes of the catchment areas and paleoclimatology, and were related to four successive tectono-sedimentary ... Read more

Facies, sequence stratigraphy and factors controlling Plio-Pleistocene lacustrine sedimentation of the area around Sohag , Nile Valley, Egypt

Facies, sequence stratigraphy and factors controlling Plio-Pleistocene lacustrine sedimentation of the area around Sohag , Nile Valley, Egypt
The outcropping Plio-Pleistocene lacustrine sediments around Sohag area extends as a separate belt occupying the proximity of fault-controlled escarpment, and are represented by the laterally interfingering Issawia and Armant formations. Based on lithofacies changes three models of lacustrine sedimentation could be identified; mixed siliciclastic-carbonates (modele 1), dominanatly siliciclastics (model, 2), and dominanantly carbonates sediments (model 3). In the first model ... Read more
