Abstract:Based on the field investigation of the Jiangsu segment of Tan-lu fault zone,integrated with the deep structures,kinematic characteristics and new research results in recent years,we discuss the characteristics of activities in quaternary for the Jiangsu segment of Tan-Lu fault zone.The activities of the Jiangsu segment are increased from south to north and from west to east.The thrusting movement with dextrorotation of Tan-Lu fault zone in quarernary was controlled by the back-arc spreading due to the subduction of west Pacific plate.The charateristics in deep structures between Southern North China block and northern North China block and the distinction of neotectonics are the significent reason for the diffe-rent characteristics of activities of each segment of Tan-Lu fault zone.
Keywords:Tan-Lu fault zone  Jiangsu segment  Quaternary activities  geodynamic setting  field investigation
