A method to estimate the total magnetization direction from a distortion analysis of magnetic anomalies

The knowledge of the declinations and inclinations of the total and induced magnetization vectors is normally required, in the interpretation of magnetic anomalies. While the direction of the last (i.e. : its declination, AF, and inclination, IF) can be likely recovered by some appropriate I.G.R.F. model, the declination and the inclination of the total magnetization vector (AT and IT) are more difficult to be determined, depending on the loc al direction of the remanent magnetization vector too.
