Abstract

The results of several sea- and ice-cores and pollen sequences of peat bogs, for the last 40.000 years, permits today to give evidence of palaeoclimatic oscillations of this period. A method of palaeoenvironment reconstitution, based on transfert functions computation, issued from pollen diagrams, is proposed. The method is building a palaeotemperature curve and a palaeohumidity curve, allowing to separate and correlate the two climatic components. A complete example of the method is developed with the data of the peat bog of Tenaghi-Philippon (Macedonia, Greece). All the analysed sequences (Tenaghi-Philippon, la Grande Pile, Banyoles, etc.), compared to sea-cores (KET 8004) and ice-cores (GRIPSummit, Greenland) confirm the evidence of mild and humid oscillations, and cold and humid oscillations, in a three parts structured sequence: the interpleniglacial (up to 28.000 BP), the late pleniglacial (between 28.000 BP and 13.500 BP), and the tardiglacial (between 13.500 BP and 10.000 BP). A numbering system, avoiding usage of ancient interstadials still to valid in their eponym sites, is proposed.
