Late Glacial and Holocene molluscan assemblages in deposits filling palaeolakes in northern Poland
Journal Title: Studia Quaternaria - Year 2013, Vol 30, Issue 1
Abstract
Late Glacial and Holocene carbonate lacustrine deposits developed as lacustrine chalk and calcareous gyttja are fairly widespread across northern Poland. They form fillings of palaeolakes which developed during the deglaciation. These formations are usually covered by peat. Rich and diversified malacofauna has been found in the aforementioned sediments. The profiles from 154 sites described and published by various authors were subjected to malacological analysis. In the whole material, 18 molluscan assemblages were distinguished, representing three types of habitats: terrestrial, of temporary water bodies, and of permanent water bodies. The composition and structure of these assemblages allows characterizing climate and differentiating habitats. The time-sequences of malacological assemblages provided possibility to define three types of malacological sequences. On the basis of these successions, a scheme of the lake water bodies evolution during Late Glacial and in northern Poland was elaborated.
