The magnetic suceptibility of Late Weichselian glacial, late‐glacial and post‐glacial deposits from Blekinge, southeast Sweden, has been measured. The susceptibility variations proved to be dependent upon the particle size distribution of the sample and the type of bedrock from which the deposit is derived. Comparison of susceptibility variations in the Baltic Ice Lake and lacustrine sediments with biological indicators of environmental change suggests that susceptibility can be a useful complement to studies aimed at identifying lake isolation, climatic change or changes in erosion within the catchment. The results also suggest that comparison of susceptibility versus fraction size curves can aid lithostratigraphic division of unconsolidated deposits.
