| Abstract: | A new method of 3-D inversion with the gravity data is presented.Using the method and taking the data of Bouguer gravity anomaly,the undulation of Moho interface and the density anomaly of upper mantle under the Himalayas and nearby regions are inversed, and the macroscale variation picture of Moho interface and the density anomaly distribution of upper mantle under these regions are given.It is shown that the thickness of the crust along the ridge of the Himalayas mountain is relatively smaller although the altitude on this region is higher. |
