Sangshutai fractures belt is in the western magin faul of Lishu fault depression, which consists of Sunjiatun fault, Xidingjia linkage fault, Sangshutai fault, Laosonglinzi linkage fault, north Jinshan fault and south Jinshan fault. In Huoshiling stage of Early Cretaceous, under the extensive environment of NW-SE, Sangshutai fault, north Jinshan fault and south Jinshan fault stretched intensely, and Sujiatun fault wasn't still active. In Shahezi stage of Early Cretaceous, Sangshutai fault, north Jinshan fault and south Jinshan fault stretched strongly, Laosonglinzi linkage fault between the above the faults was active, and Sujiatun fault also began to act, under the sinisterly strike-slip environment. Under the dextral strike-slip environment, Sujiatun fault and the northern part of Sangshutai fault were all extending strongly, Laosonglinzi linkage fault were in highly compression in Yingcheng From Denglouku stage to early Quantou stage, Sujiatun fauh, Laosonglinzi Sangsh the south Jinshan fault and stage of Early Cretaceous. utai fault, Jinshan fault and linkage fault were in transtensional strike-slip. This movement became weaker apparently and almost stopped in early Quntou stage of Early Cretaceous. So,it was covered by the thick upper Quantou Formation and Upper Cretaceous. From late Nenjiang stage to Mingshui stage, Laosonglinzi linkage fault slipped strongly and upperly cutted the Upper Cretaceous,under the NW-SE compression environment.
