Seismic geomorphology of submarine channel-belt complexes in the Pliocene of the Levant Basin, offshore central Israel

In this study, analyses of a high-resolution, three-dimensional seismic reflection dataset and well-log data were combined to characterize a distinct Pliocene interval in the Levant Basin offshore central Israel. This succession is characterised by moderate to high-amplitude, discontinuous to continuous seismic reflections between a mass transport deposit above and an undeformed basin series below. The studied interval contains two separate channelised subunits. Morphologically, the channels trend in a north to northwest direction, are incised 230 m and higher sinuosity, >1.1). The mechanisms that control the interplay between sedimentary processes and channel evolution show a cyclic pattern. Due to the cyclic occurrence of different channel types and the estimated age of the studied interval, formation and evolutionary processes of the submarine channels in the study area are likely to be controlled by relative sea level fluctuations and increased Nile River sediment supply, which is associated with rapid uplift of the Ethiopian plateau and increased African Monsoon rainfall during the Pliocene
