Received 24 July 2003; Revised 15 June 2004; Accepted 4 July 2004 ABSTRACT: This paper presents the results of a multiproxy investigation including volume mag netic susceptibility (i';;), mineral and pollen analyses of Late Glacial sediments from Lake Lautrey (Jura, France). Small-scale lithological variations have been identified with high stratigraphic resolution in order to establish lithostratigraphic correlations between cores. 1>. measurements, combined with mineralogical analyses, provide information on past sedimentary processes. This combined approach reflects major changes in terrestrial habitats and soil processes which may relate to the climatic events characterising the Late Glacial climatic warming and cooling phases. During warm intervals, the Journal of Quaternary Science record indicates increased lake productivity via carbonate precipitation and decreased input of det- ritalmaterial.
