The borehole at Radówek (Łagów Lakeland, western Poland) was made during cartographic works for the Detailed Geological Map of Poland in 1 : 50 000 scale (sheet Słubice upon Odra). Deposits of 200 m thickness were drilled. Till and lacustrine — boggy sediments have been investigated by lithopetrographical investiga-tions and by pollen analysis. This series consists of laminated gyttja with clayey laminas with shells of mollusks and floral detritus and a layer of brown-black peat. The profile of the interglacial deposits ended with finely laminated sands with organic substance. According to palynological data, the sediments in the depth 23,30 to 18,75 m belong to the Upper Warthanian Glaciation, the Eemian Interglacial and the Early Vistulian Glaciation. The described sequence lies above a 18,5 m thick layer of till correlated with lithotype till Karolewo and Naratow. This indicates its Wartanian Glaciation age. The sandy till at the top of the profile was assigned to till of Maliniec type recognized in Poznań region that is considered to be of the Early Vistulian deposits.
