Abstract

Abstract

Knowledge of the declination and inclination of the total and induced magnetization vectors is normally required for the interpretation and analysis of magnetic anomalies. A new method of estimating the direction of the total magnetization vector of magnetized rocks from magnetic anomalies is proposed. The unknown declination and inclination (* and *) can be found by applying a reduction‐to‐the‐pole operator to the measured anomalies for different couples of total magnetization direction parameters ( and ) and by observing the variation of the anomaly minimum as a function of both and *.and * are estimated using the maximum of this function. Comparing our method to previous methods, one advantage is that our estimates are not zero‐level dependent; furthermore, the method allows inclinations to be well estimated, with the same accuracy as declinations; finally declinations are not underestimated. Our method is applied to a real case and meaningful results are obtained; it is shown that the feasibility of the method is improved by removing the low‐frequency components.
