The cut plane is at Shiling town of Lishu county in Siping City of Jilin Province, where is lay on 303 state road that is 30km distance from Siping urban. According to the accurate field outcrop measurement and detailed study that we have master the geological structure and the mechanical mechanism of this cut plane, futher more it contain 39 faults and several types of folds and most of the faults are thrust of small magnitude and the rest of the other are strike slip faults, all of the faults have the same trend like YiLan-YiTong Fault Zone which is NNE or SWW. All kinds of the faults, fault complex and fold morphology, combining with areal structure setting are studied systematically. It is believed that the tectonic movement of this region Lower Cretaceous Denglouku Formation was effect by the trend change of Pacific Plate move to Eurasian Plate and it mainly has gone through two stags tectonic movement: First section sinistral strike with normal fault movement took place from late of the Early Crataceous to early of the Late Crataceous; Second stag at Early Tertiary the movement had turned to dextral strike with reverse fault.
