Abstract
We present a paleomagnetic study of 1785 to 1770 Ma composite and mafic intrusions in Småland, Sweden. A positive inverse baked contact test suggests the primary nature of their magnetization. The palaeomagnetic pole (45.7°N, 182.7°E, A~95~=8.0°) may be regarded as a key pole for Fennoscandia. Available paleomagnetic data suggest that Laurentia and Fennoscandia/Baltica drifted together since 1780 Ma until at least 1265 Ma. These two continents could form a core of a hypothetical Mesoproterozoic supercontinent.
