Abstract: This work deals with the evaluation of the structural set-up of the southern part of Sinai Peninsula, Gulf of Suez and western part of Gulf of Suez from magnetic, gravity, and seismic data. The utilised techniques including the Least Squares separation method suggest NW, NE, and E-W trends. The trend analysis shows north 35°-45° west, north 15°-25° east and E-W which may be related to the Gulf of Suez and Red Sea stresses.The Euler deconvolution illustrates that the area is highly affected by these trends. Depths range from 1 km to more than 3 km below sea level and its magnetic susceptibility ranges between 1 to 3 SI units. The 2.5D magnetic modelling and analytical signal techniques confirm the depths to the magnetic sources deduced by the Euler method, whereas the depth to the basement rocks ranges between 0 km to about 3 km indicating that it is subjected to strong tectonic activities. In addition, two seismic sections (EG-31 and MP-70), compiled by the Egyptian General Petroleum Cooperation (EGPC), were interpreted together with a geologic cross section. The studied area may be divided into several major blocks along the Gulf of Suez area. It can be concluded that the sedimentary was affected by basement tectonics as revealed by the two seismic sections.
