Abstract
The present study is concerned with the structural architecture and tectonic evolution of W. Ghoweiba segment. It is located at the northwestern onshore of the NW-trending Gulf of Suez ”GOS” rift and roughly extends in E-W direction. The sedimentary succession of the area is represented by Paleozoic-Quaternary rocks with several sedimenyary breaks. Integrated results from the surface and subsurface investigations and remote sensing mapping are showing the following main points: Facies and thickness of Jurassic sediments demonstrate accelerated tectonic subsidence and deposition in E-W trending rift basin in form of half grabens with different polarities. During the Oligocene time, continental sediments and associated volcanics were reported in the low stand area of W. Ghoweiba. These sediments are assumed to be derived from the high stand area of northern offshore GOS that was uplifted and suffered erosion during the initial Oligocene rifting of the GOS. The mapped district is clearly addressing three different structural provinces. North Galala Plateau (NGP) stands high at the south with prominent Eocene carbonate cap and very mild deformation. The middle province of Ataqa-Turah is showing extensive faulting and diversity in both of topography and rock caps. The Northern Province is the Cairo-Suez district with its depression like feature, gentle surface tectonics and younger sequences of Oligocene-Miocene sedimentary predomination
