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.
