The three-dimensional geometry of the structures affecting the suprasalt sequences above the Messinian salt in the Levant Basin (offshore Israel) is reconstructed using a depth-migrated seismic cube. We have interpreted in 3D the main faults affecting the suprasalt sequence, in where two Pliocene and two Quaternary seismic units have been distinguished. The suprasalt deformation is accomplished by NESW trending, conjugate normal faults, with planar fractures detached along the salt-top surface, and dipping both basinwards (NW) and towards the continent (SE). Faulting was initiated towards the end of the Upper Pliocene, with a major syn-sedimentary event occurring throughout the Quaternary. Syn-sedimentary faulting accompanied the down-slope gliding of the Messinian salt, expressed by distal upbuilding and local down-building or upbuilding in the marginal domain, in response to brittle, domino-like Plio-Quaternary faulting.
