Die spätglazialen sowie die frühpostglazialen Klimaverhältnisse im Bereiche der Alpen : Sauerstoffisotopenkurven kalkhaltiger Sedimente

[摘要] ¹⁸0/¹⁶0 isotope analyses on carbonate lake Sediments fromCentral Europe exhibit abrupt, characteristic variations reflectingtemperature changes. Between 13,000 and 11,000years before present, a more or less continuous warm period(Bölling-Alleröd) existed separated from the Postglacial bythe Younger Dryas cold phase. Results from 25 Sites in Central Europe, especially the forelands ot the Alps indicate, withthe exception of 3 Sites south of the Alps, a synchronouslarge-scale climatic development. Indirect dating and stratigraphic correlation of the different records was mostly performedby means of pollen analysis. Our results correlate verywell with ¹⁸0/¹⁶0 measurements on Greenland ice cores, andthey agree well with results from deep sea sediment studiesin the North Atlantic Ocean covering the Glacial-Postglacialtransition.
