| Abstract: | In this paper,the theory and method for inversing the kinematics parameters of a fault zone are discussed,and applying them,the present kinetic characteristics of Fen-wei fault zone are studied.The results show that Fen-wei fault zone extends in the direction of N22°W and is compressed in the direction of N68°E.The mean extending rate is 0.15 mm/a. |
