The Method of Separation of Magnetic Field Step by Step for Inversion of The Magnetic Geologic Interface

In this paper, the author introduces the method of separation of magnetic field step by step, which supposes the field arises from an equivalent unit‐thickness layer, whose equivalent magnetization is variable, then the equivalent magnetization of the equivalent unit‐thickness layer is inversed by separating the field, finally, the magnetic geologic interface is determined by inversing equivalent magnetization. In this paper, the author designed a model to test the method, and applied the method to one instance, the result shows the method is valid.
