“…4 and 5). These facies were previously interpreted as turbidite deposits due to their distribution at the mouth of Israeli canyons and Lebanon canyons (Hawie et al, 2013b). On the Levant margin, canyon incisions were superimposed on preexisting canyons (Druckman et al, 1995;Gardosh et al, 2008;Hawie et al, 2013b).…”

“…Contemporaneously, Messinian valleys and canyons identified on seismic lines and in drill cores, were infilled and buried (Druckman et al, 1995;Buchbinder and Zilberman, 1997;Guennoc et al, 2000). The amplitude of the sea level rise that led to the reestablishment of marine conditions in the Mediterranean is attested by the geometries of the deltaic progradational-aggradational wedges above the MES (Lofi et al, 2003;Duvail et al, 2005;Gorini et al, 2005, Kertznus andKneller, 2009;Hawie et al, 2013b. In addition, clinoform geometries are good paleodepth indicators (Urgeles et al, 2011;Rabineau et al, 2014) that provide an estimated sea level rise of 800-1000 m (above the last Messinian lowstand paleoshore position, Leroux et al, 2014).…”

“…In the northern part of the Levant margin, the onshore drainage basin is characterized by carbonate dominated rocks and restricted river systems (Hawie et al, 2013a(Hawie et al, , 2013b, which limit siliciclastic inputs. Offshore the Lebanon margin, the Messinian clastics are limited to the lower slope and the lower half of the evaporite interval (Fig.…”

International audienceThrough several examples we show that following sea-level fall and marginal erosion during the Messinian salinity crisis (MSC), clastic inputs into the eastern and western Mediterranean Sea are not distributed evenly in space and time but are mainly limited to the lower section of the Messinian salinity crisis depositional megasequence. Significant similarities around the basin allow us to propose a Mediterranean Messinian salinity crisis depositional episode that can be divided into two seismic megasequences: the Messinian lower megasequence (MLM) and the Messinian upper megasequence (MUM). Their distinctive seismic facies correspond to systems tracts deposited during three main stages that represent a complete sea level cycle. (1) A falling stage systems tract including mass transport deposits and forced regressive clinoforms deposited in in the early part of the falling stage, and related to the increasing rate of relative sea level fall. This stage is characterized by a marked shift in the depocenter towards the deep basins. (2) An early lowstand characterized by massive clastic inputs from major Messinian rivers (the Rhone, Nile, and Antalya Gulf rivers) or smaller river systems (offshore south Lebanon). These clastics were deposited in an oversaturated basin, as evidenced by the interfingering chaotic and transparent seismic facies of the Messinian lower megasequence (MLM). (3) A late lowstand, starting with rapid deposition of massive halite, with no detrital inputs into the deep basin. The upper part of the evaporites clearly onlaps the Messinian erosional surface at the margins and is evidence for a transition between a late lowstand stage and an early transgressive stage. These deposits belong to the Messinian upper megasequence (MUM). We interpret the transition between the two megasequences as the peak of the “salinity” crisis, the end of the relative sea level fall, and the maximum dispersal of sands into the deep Mediterranean basins

“…Seismic profiles (Hawie et al, 2013b) show the extent of the Upper Cretaceous stratigraphic package offshore Lebanon, where it is locally buried to depths of more than 5000 m. A comparable deeply-buried Upper Cretaceous succession has been investigated in the southern Levant basin, showing a seismic character corresponding to chalks and marls of pelagic to hemi-pelagic origin which may have reached maturity in the deep basin . However, the basinward extent, distribution, and quality of the source rock are still not known.…”

Impact of Cenozoic strike-slip tectonics on the evolution of the northern Levant Basin (offshore Lebanon)

Sedimentary basins adjacent to plate boundaries contain key tectonic and stratigraphic elements to understand how stress is transmitted through plates. The Levant Basin is a place of choice to study such elements because it flanks the Levant Fracture System and the Africa/Anatolia boundary. This paper uses new high-quality 3-D seismic reflection data to unravel the tectonic evolution of the margin of this basin during the Cenozoic, the period corresponding to the formation of the Levant Fracture System, part of the Africa/Arabia plate boundary. Four major groups of structures are identified in the interpreted Cenozoic units: NW-SE striking normal faults, NNE-SSW striking thrust-faults, ENE-WSW striking dextral strike-slip faults, and NNE trending anticlines. We demonstrate that all structures, apart of the NW-SE striking normal faults, are inherited from Mesozoic faults. Their reactivation and associated folding started during the late Miocene prior to the Messinian salinity crisis due to a NW-SE compressional stress field. No clear evidence of shortening at present-day offshore Lebanon and no large NNE-SSW strike-slip faults parallel to the restraining bend are found indicating that the Levant Fracture System is mainly contained onshore at present day. The intermittent activity of the interpreted structures correlates with the two stages of Levant Fracture System movement during late Miocene and Pliocene. This paper provides a good example of the impact of the evolution of plate boundaries on adjacent basins and indicates that any changes in the stress field, as controlled by the plate boundary, will affect immediately the preexisting structures in adjacent basins.
