Dynamique et chronologie des glaciers des Alpes occidentales françaises et leur piémont depuis le maximum du dernier cycle glaciaire

Summary: Research in the foreland of the French Western Alps has shown multiple stages of retreat or stagnation of the Lyonnais ice lobe during marine isotopic stages 4 and 2. Glaciofluvial corridors in the western part of the Lyonnais ice lobe were active during flash floods draining glacial meltwater at the Last Glacial Maximum, but are now dead valleys with terraces. Sedimentary analysis suggests these corridors correspond to tunnel valleys built during the most extensive Riss glaciation and were infilled with glacio-fluvial sediments during the Wurm maximum glacial extension.
