Quantitative values of palaeotemperature and palaeoprecipitation were reconstructed from pollen record in La Grande Pile (Guiot et al., 1989). Some weaknesses appear in the reconstruction, particularly for the cold periods and for the periods of deglaciation. From sedimentological data, i.e. organic carbon content, periglacial loess content and smectite content, it is attempted to refine the palaeoclimate reconstruction. More accurate values are calculated between the upper and the lower limits of the pollen data. During the deltaO-18 Stages 4 and 2 of the last glacial cycle, the climate was the coldest and the driest. It was less cold and more humid during the Stage 3.
