摘要：This work introduces a geologically based approach for calculation the gravity anomaly of 3-dimensional(3-D) earth model. The geologically driven earth model is decomposed into a 3-D grid and the gravity signature for different depth is calculated respectively. The results of gravity inversion are well, but when the boundary is near to 200Km, the results are very different. And as the depth increasing, the results are very similar. That is to say, the absolute depth is not sensitive for gravity inversion. In terms of the results of inversion, increasing the number of points and computing large-scale data can reduce the effect of boundary.
