Abstract

In this paper the magnetic susceptibility anistropyy technique has been evaluated for the purpose of identifying shear zones in deformed regions and for detecting movements on shear planes. The magnitude parameters and orientations of the susceptibility ellipsoid show distinct characteristic behaviour on traversing deformed zones. The actual shear lines are characterized by the very high values of anistrropy and anisttropy gradients in their vicinities. The orientational data give clear indication of any relative rotations across questionalbe boundaries. Furthermore, a semi-analytical method is outlined for determining detailed pice-meal movements along shear lines as well as giving the regional movement direction. It is not possible to quantify the movements since too many parameters are unknown.
