Abstract
Lacustrine deposits are one of the most valuable continental materials for palaeoclimatic reconstructions. They can provide high-resolution, relatively continuous records of late Pleistocene/Holocene climate. Lake sediments often contain authigenic carbonates and fossil shells whose oxygen isotopic composition is mainly controlled by that of the lake water and by temperature. During the execution of the research contract, approximately 800 samples from the laminated sediment cores raised from the lake Gosciaz, central Poland, have been analysed for {sup 18} and {sup 13}C content of lake carbonates. A remarkable feature of the sediments from the Gosciaz lake is the continuous microlamination of the 19m thick sediment column. Together with other analysed properties of the sediment (CaCO{sub 3} content, pollen analysis, AMS {sup 14}C-dating of macrofossils), the isotope data obtained provide a unique, high-resolution record of climatic changes in central Europe during the last deglaciation. Some important conclusions can be drawn from this study with respect to the chronology of the Late Glacial Holocene transition in central Europe: (i) Onset of the Younger Dryas was as abrupt as its termination - both were completed within approximately 70 years; (ii) The apparent duration of the Younger Dryas, determined by direct counting of annual varves preserved
