Abstract: The problems in Parker-Oldenburg potential data inversion method has been analyzed, the Genetic inversion method which combining both fast forward method in frequency domain and Genetic Algorithms has been put forward in this paper. To counter the problem that convergence is slow in Genetic Algorithms, two improved measures were adopted, which made this Genetic inversion more perfection. After computing on theoretical models and using real data, the effection of this potential Genetic inversion method was verified.
