Soft-sediment deformation structures (SSDS) in the Late Messinian Abu Madi Formation, onshore Nile Delta, Egypt: triggers and tectono-stratigraphic implications

Several levels of soft sediment deformation structures (SSDS) were observed in the transgressive heterolithic fluvial facies deposited adjacent to the deep-seated faults. The most common deformation features include diapiric structures, intraformational lithoclastic breccia, small-scale normal, slump folds and liquefied beds
