We analyze the neo-tectonic characteristics and their evolution in the Weihe basin.Based on the faulting segment study of the north Qinling fault,the faulting activity of the Kouzhen-Guanshan fault may correspond to the segment of the north Qinling fault,which has the strongest faulting activity.Then the influence of the Kouzhen-Guanshan fault,including other north margin faults of the Weihe basin,are modelled by FEM,under the condition that the north Qinling and the Huashan front faults are the main and controlling active faults in the Weihe basin.The results show that the faulting activity of the Kouzhen-Guanshan fault corresponds to the east segment of the north Qinling fault.Furthermore,as a preexisting and unsubstantial tectonic belt fault,the Kouzhen-Guanshan fault is easier to aggravate the above-mentioned effect and has stronger faulting activity than other north margin faults of the Weihe basin.
