Abstract

The studied area is located on the boundary between Levant basin, Sinai sub-plate and eastern Nile cone, all of them affecting its evolution and producing a complex structural and stratigraphical composition. Two major megasequences with different structural styles and trends can be determined in the area, separated by Messinian layer consisting of evaporates changing laterally into shales and carbonates. This layer isolates tectonic stresses and controls the distribution of structural features in the overlying sequence. In Pre-Messinian, there are structural features that correspond to the regional geology, that were not previously recognized in the area. One of the examples is Pelusium shear zone, which was determined being active at Oligocene with sinistral strike-slip movement, reactivating the inverted structures and producing high narrow anticlines. Sediment input from Nile had mostly played fewer role in the evolution of Post-Messinian sequence than the local source in SE, and the direction of gravitational extension was mostly NW. Petroleum system analysis showed that Cenozoic shales are not mature, hence the hydrocarbon potential of Post-Messinian turbidite sandstones is limited. The strong inversion and strike-slip movement had breached seals of Pre-Messinian structures, explaining dry wells, although there are some promising plays which are the structures without faults
