Abstracts

Recent corings have been carried out in the Evian area, allowing us to describe in details new hectometric profiles of detritical sedimentary deposits. Various sediments have been observed throughout the Quaternary sequences: glacio-lacustrine facies, basal and lateral till, and organic-rich layers (including lignite and peat). Three major stratigraphical units have been identified:
• The “Complexe Inférieur”, mainly composed of glacio-lacustrine sediments, dated before 30 000 yr B.P. and prior to the L.G.M.
• The “Complexe du Plateau Gavot”, deposited between 30 000 and 27 000 yr B.P., in the sedimentological context of active glacial margin.
Therefore, this unit recorded at least fifteen lateral fluctuations of the Rhône glacier margin. Some oscillations could have exceeded one kilometer of extension in latitude,
• The “Complexe emboîté”, mainly composed of glacio-lacustrine sediments, deposited between 25 000 and 21 000 yr. BP. This Unit fits well with the boundary between high and low kame terraces located in the surroundings of Thonon-Les-Bains.
