| Abstract: | The Quaternary sections of the Nile Cone in the eastern Mediterranean are formed by regionally extensive repetitions of sediment sequences (cyclothems s.l.) showing a successive, orderly arrangement of sediment types. Detailed lithofacies analysis reveals the recurrence of three basic terms in many cores: a basal olive-gray hemipelagic mud and turbidite sequence; a middle sapropel sequence; and an upper yellowish-orange hemipelagic sequence, including calcareous ooze, and a turbiditic sequence. This cyclic sedimentation closely reflects the Quaternary dynamics. The development of the Nile submarine fan in an enclosed, silled basin has resulted in a particularly close relation between biogenic-terrigenous depositional patterns and climatic and oceanographic factors affecting the Mediterranean. |
