Synchronous Early Holocene glacier behavior in the European Alps – Evidences from a new cosmogenic 10Be chronology of Argentière glacier (Mont-Blanc massif, French Alps).
Reconstruction of past glacier fluctuations is an important step towards the comprehension of glacier responseto past and future climate changes. Moraine deposits and roches moutonnées represent univocal geomorphicmarkers of advanced glacier extensions, and their dating using in situ-produced cosmogenic nuclides is a valuableapproach for better constraining past glacier behavior.To better understand the past glacier fluctuations in the European Alps, this study focuses on the Argentièreglacier, located on the north-western flank of the Mont-Blanc massif (MBM) in the Western Alps, and hostingsome of the largest European glaciers. Here, gemorphological analysis and new 10Be exposure ages obta…
