Abstract: Physical properties of rocks, velocity, density, magnetic susceptibility and resistivity are analyzed statistically to look into their inherent relationships. First, various useful information is used to establish a comprehensive physical geological model. Then the model is modified according to the inversions of gravity, magnetism, MT and seismic data. Finally, a modified comprehensive model is obtained by the integrated inversion of all the available geophysical data.

摘要： 首先对岩石的速度、密度、磁化率、电阻率等物性资料进行统计分析,寻找它们之间的内在联系,在此基础上综合各种有用信息建立统一的物理-地质模型。在统一的物理-地质模型之上,进行重、磁、电、震单一方法的反演,分析各种物探方法反演结果的相容性与相背性,重新修改模型并进行重、磁、电、震的联合反演,最终确定深部地层的地质属性。
