Summary/Abstract: This article presents the results of measurements of the anisotropy of magnetic susceptibility (AMS) of Quaternary sediments collected from 13 sites, located in zones I–IV of glacigenic forms in SE of the Łódź Region. Based on statistical analysis and graphical position of the principal axes of ellipsoids illustrating the magnetic susceptibility tensors, recreated directions of transport for 206 samples, mainly of glacial sediment of different ages and types. The usefulness of AMS analysis in determining the direction of transport in clasts of the till has been proved and also to verification of the directional results of other measurements in the sediments layered.
