Abstract:
For the purpose of providing fundamental data to study the lithosphere dynamic characteristics and the controlling or influence on rupture activity, monitoring and preventing the geological disaster and earthquake, this paper processes the practical seismic data includeing west-east and north-south sections. Selects separating field and displacing digital imaging to process the gravity and magnetic data, analyzes the earth’ s crust structure and main rupture as well as Moho fluctuating. The 2-D structure section was achieved through joint inversion. The results indicate that the strategy is appropriate and the results are reliable. Along the main section. The interpretable rupture can be classified into three suits, first class(Ⅰ)is super lithosphere rupture that cuts deeply to up mantal, second class(Ⅱ)is lithosphere rupture that exists in the Earth crust, third class(Ⅲ)is rupture in covering layer(including fundus rupture). According to geophysical features. The rup- ture structure characteristics can be accurately got, and the results agree with the real situation quite well.
