Architecture, geodynamic evolution and sedimentary filling of the levant basin : a 3D quantitative approach based on seismic data

Abstract : Sedimentological and biostratigraphic investigations onshore Lebanon coupled with 2D offshore reflection seismic data allowed proposing a new Mesozoic-Present tectono-stratigraphic framework for the northern Levant Margin and Basin. The seismic interpretation supported by in-depth facies analysis permitted to depict the potential depositional environments offshore Lebanon as no well has yet been drilled. The Levant region has been affected by successive geodynamic events that modified the architecture of its margin and basin from a Late Triassic to Middle Jurassic rift into a Late Cretaceous subduction followed by collision and Miocene-Present strike slip motion. The interplay between major geodynamic events as well as sea level fluctuations impacted on the sedimentary infill of the basin. During Jurassic and Cretaceous, the Levant Margin is dominated by the aggradation of a carbonate platform while deepwater mixed-systems prevailed in the basin during the Oligo-Miocene, three major sedimentary pathways are expected to drive important quantities of clastic material into the Levant Basin: (1) canyons along the Levant Margin, (2) the Latakia region (coastlal Syria) and (3) the Nile Deep sea cone. Regional drainage system analysis was performed to estimate the contribution of the different sediment sources to the infill of the basin. A numerical stratigraphic forward model, Dionisos, was used to test the Middle-Late Miocene source-to-sink scenarios permitting to better assess the plausibility of the expected sedimentary volumes for each source through a comparison with actual drainage systems
