The normal faults developed through the period of the most recent orogeny. In this study, normal fault systems were analyzed with seismic interpretation, Allan map, or fault plane analysis, D-L profile and T-Z plot. Normal fault evolutionary history was constructed by the study of normal faults interaction and linkage. There are two stage of normal faulting. In Late Mid-Miocene, normal faulting was active. In the following stage till the end of normal faulting in the beginning of the Pleistocene, slip rate along the normal faults significantly reduced. Also, normal faulting was more active in the western part of the study area in the early stage, and gradually transferred to the east.
