Weichselian sediment succession at Ruunaa, Finland, indicating a Mid‐Weichselian ice‐free interval in eastern Fennoscandia
Core material obtained from three boreholes was studied from the Ruunaa area, Finnish northern Karelia, in order to reveal the Late Pleistocene environmental history of eastern Finland. Conventional litho‐ and biostratigraphical methods were used and suitable sediment samples were dated using quartz...
