| 英文摘要 | This paper proposes a new strategy for conducting model analysis with gravity anomaly and seismic data, in which the gravity response of inhomogeneous mantle should be taken into account. Model calculations and a case study in the Sichuan basin demonstrate this strategy a good potential to make the gravity data processing and inversion more consistent with the actual geological conditions. By collecting the comprehensive geophysical research results in many regions around the world, as well as the corresponding deep mantle structure, we find the lateral inhomogeneity of the mantle is widely distributed in the petroliferous basins, continental margins, ocean-continent transitions and other geological sites of general interest. However, in many joint studies based on gravity and seismic data, model analysis is usually performed within the crust. Although it simplifies the difficulty of the model analysis, the gravity anomaly caused by deep earth inhomogeneity should have been considered, otherwise the inverted density structure and interpretations may deviate the actual geological conditions. Therefore, based on the 2D forward modeling, this paper evaluates the quantitative effect of inhomogeneous mantle on Bouguer anomaly. Moreover, in a case study of the Sichuan basin, the results of the 2. 5D joint simulation taking into account the inhomogeneous mantle are obviously better than those of following the homogeneous mantle hypothesis. |
