| Abstract: | The variable density multilayered crustal model is put forward according to the idea of model decompose in this paper, and the corresponding gravity forward formula is deduced. The genetic inversionmethod of multilayered crustal structure is pressented based on genetic algorithms and combined withthe above-mentioned formula. The crustal density structure along the Zhengzhou -Ling fen profile isobtained by means of forward modeling and inversion, and, the mechanism of gravity anomaly is analyzed according to the obtained results. |
