Late Weichselian sediments from two lake basins in southeast Sweden, dated with pollen and radiocarbon in an earlier investigation, have been analysed with respect to their paleomagnetic records. The directional changes of the absolute declination from the two basins are very similar. A strong and quite long-lasting westerly declination maximum during the Allerød Chronozone does gradually turn over to a less strong easterly maximum of short duration around 10,200 B.P. After that another westerly peak seem to follow. The inclination record is reliable from only one site and the filtered curve indicates eight peaks. These geomagnetic records are regarded as good reflections of the secular variations in south Sweden during the Allerød and Younger Dryas Chronozones.
