| Abstract: | The Parker-Oldenburg iterative inversion method with constant density and variable density model was applied to the Three Gorges dam region. Comparing and analyzing the reversed results with the two models, we can obtain of the accurance undulation the upper, middle and lower crust interfaces(B3,B2,B1). The results indicated that the variable density model’s reverse results is more reliable，the general morphological characteristics of two reverse results are consistent. Between the differences of the inversion results, change of B2 is the most, the maximum difference reaches 4 km; the thickness of the middle crust in the Three Gorges dam is about 9 km which is the thinnest area in the Three Gorges region. |
