The varied and complex styles of soft-sediment deformation structures are well preserved in Late Ordovician deposits of Manjiaer depression and its adjacent areas in Tarim basin located in Northwestern China. A large variety of ductile and brittle deformation structures were observed in drilled well cores sediments of the continental shelf - basin facies deposition in Late Ordovician. They contain liquefied sand veins, liquefied breccia, diaper-like structure, hydroplastic convolutions, and seismic unconformity and so on. Especially, the extensive meter-scale horizon of soft-sediment deformation was observed in the joints of Katake uplift and Manjiaer depression, presence of the seismites sequence combination of mainly boudinage-like soft-sediment deformation structure and little liquefied sand vein and breccia, formed during unconsolidation by shear-extensional regional tectonic setting. The deformations layers interval characterized by unreformed beds with different thickness. These structure deformations resulted from the seismic deposited, the deformational characteristics presented extentional environment , and the palaeostress intensity increased from early to late in the earlier Late Ordovician. The multi palaeo-seismic records were association with multiphase of activities of the main earthquake fault. The Paleo-seismic records indicated that the Tazhong 1 fault was an active earthquake fault in the Late Ordovician, the nature and activity of this fault are different at the different phase, and the different parts. They were responded to the Caledonian movement on Manjiaer depression and its surrounding. The palaeo-seism of the fault affected palaeotectonics and palaeosediments on evolution in research area in the Late Ordovician.
