“…The origin and even the presence of this strike-slip activity is still a matter of debate. Alternatively to deep rooted shear zones, normal listric faulting in the slope area was associated with the pinch-out of the evaporites (Garfunkel, 1984;Almagor, 1984), or possibly with their updoming (Ben-Avraham, 1978). Bellaiche et al (1999) and Gaullier et al (2000) showed from bathymetric and seismic data that in the very south of the Levantine Basin in the Nile delta near-surface faults running parallel and perpendicular to the slope are caused by gravity gliding.…”

“…The Plio-Quaternary deposits overlie the Messinian evaporites unconformably (Almagor, 1984) and mainly consist of Nile derived sediments (Ross and Uchupi, 1977). South of Haifa the continental shelf and slope are formed by the easternmost part of the Nile fan (Almagor, 1984;Buchbinder et al, 1993) and a broad and smooth shelf.…”

“…South of Haifa the continental shelf and slope are formed by the easternmost part of the Nile fan (Almagor, 1984;Buchbinder et al, 1993) and a broad and smooth shelf. To the north the shelf is narrow and the continental slope steep and irregular (Neev, 1976;Almagor and Hall, 1984).…”

“…The reflections bounding the bottom of the Plio-Quaternary sediments and the bottom of the Messinian evaporites are termed M-and N-reflection, respectively (Ryan et al, 1970). The M-reflection was traced throughout the whole Mediterranean Sea as an erosional unconformity (Hsü et al, 1973;Almagor, 1984).…”

“…In the 70s and 80s, the eastern Levantine Basin was recognized as a world class site to investigate this lateral salt tectonics, which includes significant lateral salt flow and complex deformation of the sedimentary overburden (e.g. Garfunkel et al, 1979;Almagor, 1984;Garfunkel, 1984;and others). Lateral displacements were studied by analog, later also by numerical modeling (Gemmer et al, 2004).…”

Internal deformation of the southeast Levant margin through continued activity of buried mass transport deposits

Mass transport deposits (MTDs) are commonly regarded as motionless evidences of past mass wasting events. Three‐dimensional seismic surveys acquired offshore central Israel reveal continued long‐lasting and even current deformation of >1.5 Myr old MTDs, now buried hundreds of meters beneath and still impacting the seafloor. Faulting and folding of the Messinian‐Pliocene unconformity (M), at the base of the studied interval, represent the possible impacts of tectonic and halokinematic deformation. However, an ~200 m thick continuous stratified unit straddles the M and entirely separates the overlaying Plio‐Quaternary sedimentary stack from underlying faulting. Overlaying and etched into this stratified unit are headscarp regions of two up to 450 m thick buried MTDs, characterized by distinct combinations of chaotic seismic reflections and typically ~1 km wide detached and rotated blocks. “Crowns” of growth faults emanate upward from these MTD headwalls, truncating and deforming the overburden and offsetting overlaying reflections by tens of meters up to ~100 m below the seafloor. Moreover, asymmetric sagging and faulting of the overburden mimic the layout and flow pattern of the MTDs and rafted blocks within, providing kinematic indications of combined compaction and lateral flow. These observations imply that the MTDs undergo continuous postslumping differential compaction, combined with lateral mobilization. Additional smaller and younger buried MTDs distributed within the overburden are observed to portray similar deformation kinematics. We suggest that the buried MTDs provide deformational foci and pathways for downslope internal collapse of the continental margin at large, offering a new possible mechanism of thin‐skinned extension.
