The complex syn- sedimentary deformation structures induced by slump deposits in continental lacustrine basins are essential when interpreting paleotopography and ancient earthquakes. A systematic study on the slump deformation system is conducive to the identification of deformation origin, understanding of deformation mechanism and deeply interpretation of regional tectonic background.Methods:Based on a literature review, we summarize the forming conditions and deformation characteristics of slump deposits along the slope, especially the morphological evolution of slump folds, the associated deformation structures, indication of the ancient slope and physical simulation.Results: Comprehensive analysis shows that: (1) slump deformation in continental lacustrine basin is closely related to gravity flow deposition; (2) cylindrical fold and tight upright fold are at head of single slump body while mushroom- shaped fold at toe, the morphology evolution of these folds can be divided into several stages; (3) thrust faults, clastic dykes, irregular erosion surfaces and soft boudinage can be seen in slump folds; (4) stress mechanism and liquefaction mechanism are the two main mechanism of slump deformation; (5) physical simulation may become an important aspect of slump deformation study due to its changeable parameters of materials.Conclusions: Disputes still exist in the identification of deformation origin. Sediment reworking, remobilization, bioturbation and liquefaction of unconsolidated sediments are the key indicators of soft- sediment deformation.
