Based on an analysis of the sedimentary deformation structure, the authors found that the deformation structure belongs to the soft-sediment deformation structure formed in a shallow slope facies at the bottom of Neoproterozoic Sishilichangshan Formation in Shouxian County of Anhui Province. Multiple seismic waves produced in seismic events caused soft-sediment slumping, fold slip and liquid discharge through the shock and sliding rolling deformation activities, resulting in the formation of the soft-sediment deformation composite structure with complex deformation features. The soft-sediment deformation structure is a record of the multiple seismic activities in one seismic event.
