The northeast margin of the Nubian Craton, comprising the Eastern Desert, the Gulf of Suez and Southwest Sinai, contains sedimentary units ranging in age from early Palaeozoic to Tertiary. Below the extensive Late Cretaceous marine transgressive units, older rocks, especially those of the Palaeozoic and early Mesozoic, have limited spatial distribution. The entire sequence is present, however, with major breaks, along the northeastern flank of the Red Sea basement high, in the subsurface Gulf of Suez and in southwest Sinai. The Eastern Desert Platform, on the other hand, is mantled by Cretaceous and younger sediments suggesting that the area was a topographic high until about the end of Jurassic, or that the area suffered post-Palaeozoic uplifting. The Palaeo-Mesozoic sequences in the Gulf of Suez lowlands and adjoining areas attest at least four episodes of marine incursions during (1) Early Palaeozoic (Cambro-Silurian?), (2) Early Carboniferous, (3) Middle Jurassic and (4) Late Cretaceous. Except for the Jurassic transgression, each episode was interrupted by a brief but rapid fluvial progradation. Such brief and rapid progradational interruptions of the major transgressive episodes were probably caused by vertical block movements. The early Palaeozoic and Late Cretaceous progradations show northerly to northwesterly dispersal suggesting northeast to easterly trending vertical movements, whereas the Early Carboniferous progradation was in a general easterly direction indicating approximately N-S trending block movements. Sporadic occurrence of Middle Jurassic sediments in isolated fault blocks below extensive Cretaceous units in the northern Gulf of Suez outcrops, their abrupt thickness change in the subsurface of north central gulf and the occurrence of fault controlled basic dikes and sills within these rocks point to a Late Jurassic-Early Cretaceous extensional episode and resultant block movements in the area. A minor episode of Early Cretaceous local block movement in the Gulf of Suez area is indicated by the occurrence of an unique polymictic conglomerate containing angular pebbles of chert, banded iron formation, jasper and metavolcanic rocks at the base of the lower Cretaceous Malha Formation in the southwest Sinai and northern Gulf of Suez outcrops. Source rocks for this conglomerate occur in the Precambrian basement southwest of Quseir and in western Saudi Arabia. Recurrent pre-Tertiary block movements parallel to the Miocene Suez-Aqaba rifts and associated fault blocks suggest control of the pre-Miocene structural elements in the development of the latest rift system in the area. Careful lineament analyses of the Precambrian basement and fringing sedimentary cover may be helpful in locating and dating some of the pre-Miocene crustal fracture zones in the area.
