THE LAST CLIMATIC CYCLE AT LA-GRANDE PILE (VOSGES, FRANCE) A NEW POLLEN PROFILE

A new pollen diagram has been made from an old unanalyzed core from La Grande Pile (GP XX). Correlations with the previous work of Woillard (1975-1978) leads to the following conclusions: the end of the Eemian was marked by a minor climatic change prior to the Melisey I stadial; the Ognon II and Ognon III interstadials are not consistent, and correspond to the level of reworking of mesophilous taxa during the last Pleniglacial; the limitations of the botanical interpretation of pollen spectra from the last Pleniglacial are underlined; lastly, Bruckenthalia and Larix are identified for the first time at La Grande Pile. The respective roles of these taxa following the Eemian are additional arguments for correlating the St-Germain I and II with the Early Weichsel interstadials in the north of middle Europe.
