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

在紧邻深断裂沉积的海侵互层状河流相地层中，观测到多级软沉积物变形构造（soft sediment deformation structures, SSDS）。其中最常见的变形特征包括底辟构造、层内岩屑角砾岩、小型正断层、滑塌褶皱以及液化沉积层。
