- Abstract:
- In this paper,three rotation modes of fault twist(W1),torsion(W2),and warp(W3)are defined by the rotation basis of the left end point of the footwall,and with three translation modes of fault strike-slip(U1),dip-slip(U2),and extension/press(U3)together to describe the movement of faults in space.The three-dimensional corner point method is used to calculate the gravity changes caused by different combinations of translation and rotation of vertical faults.The conclusion is that the variation distribution of the gravity change field produced by the fault in the single rotation mode is symmetrically distributed along the fault axis.The response of the fault in the same rotational mode is different from that of the different translation modes.When the fault is in the W1 rotation mode,the gravity changes caused by the combination mode with U2 is most significant.When the fault is in the W2 rotation mode,the gravity changes caused by the combination mode with U3 is most significant,But in the W3 mode,the gravity distribution of the U3 translation combined mode is caused by the outward expansion of the U3 model.The distribution of the ground gravity changes caused by the combined movement mode of the mixed rotation and the mixed translation,and its distribution of the principal distribution is consistent with that of the mixed rotation mode,while exhibiting a hybrid translational mode response.
