3D DENSITY INVERSION WITH GENETIC ALGORITHM

Ke Xiaoping,Wang Yong and Xu Houze(Institute of Geodesy and Geophysics,CAS,Wuhan430077)  
A new inversion method for 3D density structure is proposed,which combines the method of gravity forward of 3D rectangular prism with genetic algorithm,the approach of constructing the objective function and the procedure of genetic algorithm are introduced.The validity and stability of this method are proved by synthetic data.With this method the three-dimensional distribution of density in eastern Qinghai-Tibet plateau is inverted from Bouguer gravity anomaly.
