Onshore-offshore seismic interpretation allowed mapping of the Jurassic and Cretaceous Egyptian platform margin.

Seismic geomorphology of the margin and the hinge line from Western Desert to Sinai is revealed.

Jurassic carbonate platform was mainly prograding and showed gentle slope profiles with punctual sedimentary transfer axis.

Cretaceous platform margin showed different slope profiles: subvertical scarps and distally steepened segments.

Mass Transport Complex deposits sourced by the dismantling of the Mesozic platform are located on the slope and basin.
