Abstract：The density interface inversion is one of the most important methods for processing and analyzing potential field data.In order to adapt to strata density change with the depth and enhance the density interface inversion,we propose in this paper an interface inversion in the frequency domain based on the hyperbolic density interface model.The formulas of the interface forward modeling and inversion in the frequency domain are derived under the density model,and the iterative calculation process of the inversion is listed.The model test shows that the proposed method is more sui-table for the interface inversion of variable-density strata and its accuracy is higher than that of the Parker-Oldenburg method which is suitable for constant density interface.In the real data processing in Hulin Basin,the effectiveness and practicality of the proposed method are proved by the evidences of MT sounding and previous studies.
