An automated method for the interpretation of magnetic vertical-gradient anomalies

The use of airborne magnetic vertical‐gradient surveys is increasing. Interpretation, however, is mostly used qualitatively as an aid to geologic mapping. Presently, quantitative interpretation techniques are based on the analysis of isolated anomalies. In this paper, we develop a numerical method for interpreting the magnetic vertical‐gradient anomalies of dipping dikes and planar geologic contacts. The method is based on a linearization of …
