Flora, vegetation and climate at Sokli, northeastern Fennoscandia, during the Weichselian Middle Pleniglacial
A 2 m thick laminated lacustrine deposit of silt and clay recovered from the high‐latitudinal site at Sokli (northern Finland) provides a unique mid‐Weichselian fossil record for Fennoscandia. High‐resolution botanical and zoological analyses of the lacustrine deposit allow detailed reconstruction o...
