Abstract

Various methods have been proposed to interpret the self-potential anomalies due to sheet-like bodies. A common point of all existing interpretation methods is the assumption that earth is geoelectrically homogeneous. We propose a non-linear inversion approach for SP anomalies which finds the optimized sheet-like body for a given arbitrarily resistivity distribution. Tests of the new technique with synthetic data suggest that it can produce more accurate and reliable results. Further, test with field data demonstrate the applicability of the scheme in real problems.
