Abstract

Sandy sediments of various origin and age dominate Quaternary geologic structure of the Odra Bank region. Three sediment series identified in numerous borehole section and dated using radiocarbon method represent sediments of the Interpleniglacial, the Late Vistulian Glaciation, and the Holocene. The oldest series composed of sands, locally silly sands with organic matter and coalified organic remains, formed in the Interpleniglacial of the Vistulian Glaciation. Younger series is represented by the marshy-lacustrine sediments, which formed in the Late Glacial and the Early Holocene. The youngest series is composed or marine sands. Stages of the region development were determined based on results of radiocarbon dating. Two dates are the most significant: 14 060 years BP, which indicates beginning of the peat accumulation in the studied region, and 5190 years BP, which indicates the beginning of the Littorina Sea transgression into the Odra Bank.
