Schematic geologic cross section of the Nile Delta Basin Province illustrating the geologic definition of three of the four assessment units (AU) in this study (dotted red lines): Nile Margin Reservoir AU, Nile Cone AU, and Eratosthenes Seamount AU. The new and active delta builds seaward, developing distributaries and splays until it also is eventually abandoned, and another site for active sedimentation is formed. Boggs defines a delta as any deposit, subaerial or subaqueous, formed by fluvial sediments that build into a standing body of water. Example: Nile delta This delta begins to split into distributaries at Cairo, Egypt, more than 160 km inland, and fans out over the entire delta. Such deltas are very often formed in the regions of semi-arid climate. Geology Department, Faculty of Science, Suez Canal University, Ismailia, Egypt . Erosion, salinization, and pollution are inducing a marked … Abstract . Few countries in the world are as dependent on water from a single source as Egypt. Arcuate deltas are formed of coarser materials including gravels, sands and silt. Figure 2. Abu Madi/El Qar’a is a giant field located in the northeastern part of Nile Delta and is an important hydrocarbon province in Egypt; however, 18.17), which is also called as Nile type of delta. The source of the Nile is sometimes considered to be Lake Victoria, but the lake has feeder rivers of considerable size. The Nile delta is also shrinking as a result of the Aswan Dam and other river management techniques. New study calculates the delta’s subsidence on the basis of satellite data. 2Geology Department, Faculty of Science, Helwan University, Cairo, Egypt . The continental shelf off the Nile Delta is covered by terrigenous sands on the shore face, by terrigenous muds on the middle shelf, and by algal carbonates on the outer shelf. In this paper, organic matter content, type, and maturity of source rocks have been evaluated and integrated with the results of basin modeling to improve our understanding of … Nile Delta: Marine Geology, v. 44, p. 253–272. 2.2. In addition to data from the Nile delta cone, we present the first detrital zircon U–Pb and hafnium isotope data for Saharan dune sands, in order to constrain the composition of aeolian input into Nile delta sediments. The main river is bifurcated into numerous channels known as distributaries. Geology of the Nile River catchment and hinterland The natural Nile cycle of flow and sediment discharge has been disrupted by human intervention, including closure of the High Aswan Dam; this intervention has resulted in a series of responses that now threaten the northern Nile delta. 3. The team traced the geologic history of the Nile, correlating it with information from volcanic rocks and sedimentary deposits under the Nile Delta. How Fast Is the Nile Delta Sinking? Without silt and other sediments to fortify it in a prodelta, the waves of the Mediterranean Sea are eroding the delta faster than the Nile can replace it. Abu Madi/El Qar'a is a giant field located in the north eastern part of Nile Delta and is an important hydrocarbon province in Egypt, but the origin of hydrocarbons and their migration are not fully understood. The Nile Delta is the best example of arcuate deltas (fig. Source: Journal of Geophysical Research: Solid Earth The Nile Delta … As the Holocene transgression began, Nile mud was discharged directly on to the Nile Submarine Fan. The Kagera River, which flows into Lake Victoria near the Tanzanian town of Bukoba, is the longest feeder, although sources do not agree on which is the longest tributary of the Kagera and hence the most distant source of the Nile itself.
