Research output: Contribution to journalArticlepeer-review


New seismic data provide information on the structural development and late Tertiary stratigraphy off N.Sinai. The upper continental slope is characterized by a series of platforms or steps. The lower continental slope is smooth, except for one low ridge. Numerous diapiric structures along the continental margin N of the Sinai Peninsula emerge from an evaporitic layer of late Tertiary age. The diapirs usually are aligned along WNW-trending faults. A salt ridge produces a submarine ridge in the lower continental rise. Two main fault trends have been mapped. In the W part of the continental margin they trend WNW and, in the E part, NE. These parallel the continental slopes of N.Sinai and S.Israel. The structural grain is controlled by two main tectonic elements: 1) rejuvenated basement faults of the continent-ocean transition zone; and 2) salt diapirism due to loading of Messinian evaporites with Nile-derived clastics.-from Authors
