A study on effects of shallow inhomogeneous body on object resistivity anomaly.
浅部不均匀体对目标体电阻率异常影响的研究

It is well known that the critical distortion to resistivity sounding curves could be produced by shallow inhomogeneous bodies. In order to eliminate this interference, this paper adopts the 3 D finite element numerical simulation method to calculate the pure anomaly caused by an inhomogeneous body at shallow depth and a mixed body (object and the inhomogeneous body) anomaly, and corrects them through other correction methods. Finally we realize the quantitative correction for the inhomogeneous body at shallow depth.
