Opis:: Depression in the Quaternary bedrock in the Lower Vistula Region was a main route for the Scandinavian ice sheets advancing into the Polish Lowland. At the end of the Elsterian Glaciation the receding ice sheet dammed the meltwaters in the Lower Vistula Valley and in its vicinity. The Holstein sea presumably occupied the Gulf of Gdańsk as indicated by brackish deposits of this age in the Kaliningrad District. During the Eemian Interglacial an extensive sea bay existed in the Lower Vistula Region. The Lower Vistula Region is a stratotype area for the Vistulian Glaciation (Weichselian), with several ice sheet advances, also before the Last Glacial Maximum.

Opis:: Fluvial sediments in the Chłapowo cliff section were studied in order to reconstruct their palaeoflow conditions and stratigraphical position. Lithofacies, textural and palaeohydraulic analyses as well as luminescence dating were performed so as to achieve the aim of study. Sedimentary successions were identified as a record of point bar cycles. The fluvial environment probably functioned during the latest Saalian, shortly after the retreat of the Scandinavian Ice Sheet. Discharge outflow was directed to the northwest. The river used the older fluvioglacial valley and probably was directly connected to the Eem Sea. Good preservation and strong aggradation of point-bar cycles were related to a rapid relative base level rise. The meandering river sediments recognised showed responses to climate and sea level changes as illustrated by stratigraphical, morphological and sedimentological features of the strata described. The present study also revealed several insights into proper interpretation of meandering fluvial successions, in which the most important were: specific lithofacies assemblage of GSt (St, Sp) → Sl → SFrc → Fm (SFr) and related architectural elements: channel/sandy bedforms CH/SB → lateral accretion deposits LA → floodplain fines with crevasse splays FF (CS); upward-fining grain size and decreasing content of denser heavy minerals; estimated low-energy flow regime with a mean depth of 1.6–3.3 m, a Froude number of 0.2–0.4 and a sinuosity of 1.5.
