Abstract

This paper summarizes the results of palaeosecular variation (PSV) studies carried out since 1983 in south Sweden. South Sweden is for a number of reasons considered to be a suitable area for these studies. Different types of sediment, covering different periods almost back to the deglaciation, have been analysed. From the Late Weichselian a repeatable pattern of PSV curves have been established. Sediment, dated both with radiocarbon chronology and varve chronology (absolute years BP), indicate a difference between the two time scales. Further investigations will be carried out to confirm these results. Long core palaeomagnetic analyses of a ca 20 m long Holocene sediment succession have resulted in a preliminary PSV curve from this period. With respect to the documented pattern and age of identified turning points, features from both the east European and west European master curves, as presented by Thompson (1983), are found. The preliminary result from this single profile are promising and further investigations from this site will be carried out in the near future.
