Late-glacial and early Holocene climatic events and chronology of vegetation development in the Netherlands

摘要: The Weichselian Late-glacial marks the transition from Late Pleniglacial to warmer Holocene. During this period climate changed rapidly, as did vegetation and abiotic landscape. For analysis of relationship between these changes, accurate chronologies are essential. In Netherlands, a compilation has been made over 250 palynologically investigated sites relating period. A regional zonation constructed based on common trends in development. On palynological grounds, not only classical sub-division but also minor changes can be recognized within Allerod, Dryas Early Preboreal. After critical evaluation available radiocarbon dates attached the14C timescale. Palynological which attributed episodes climatic cooling recorded at 12 100, 11 500, 10 950 9950 B.P. chronological framework it possible compare development with other proxy records.
