K. 3 Geology Department, Faculty of Science, Cairo University Wide varieties of deformation patterns, including complex folds, thrust and normal faults, rafts, diapirs, fisher-street, and liquefaction vents, are traced and measured in a purpose of strain-stress analysis of the Hammam Faraun district, located at the NE-side of the Gulf of Suez. Gravitationally driven slumping deformations are found restricted in the Eocene and Lower Miocene sequences. It is essentially generated by shear mechanism, which was found accelerating in both directions of toe-front and the decollement surface. The shear-related structures are traced in complex patterns and frequent existence near the decollement surfaces and own intricated contractional features near the toe-front. Proceeding of glided slabs from the head of gliding (extensional strain), to the toe-front (compressional domain) have been resulted in overprinting of the extensional structures by superimposed contractional forms. The Eocene basin and intrabasinal ridges had been equated by Eocene tectonics that caused ridge uplifting, denudation and block-detachment. These charged the warped seabed basinal troughs and triggered gravitational tectonics and formation of olistostromes. Gravitational tectonics within the open marine Lower Miocene sediments are attributed to basin - slopes that created by rapid subsidence and downward movements along the bounding rift-related faults.
