Abstract

Recent sedimentary processes in the "Haut-lac" (Lake Geneva) infered from bottom morphology and sedimentological analyses of surficial deposits. The lake bottom in the eastern part of Lake Geneva (Haut-lac) consists of a sublacustrine fan, with a 15km long valley occuring from the Rhone River mouth to the deepest part of the lake. Numerous echosounding profiles collected in this part of the lake has been able to identify the fan morphology and to trace the precises location of the valley on the lake bottom. Grain size measurements and geochemical analyses of surficial bottom sediments show that the sedimentary processes that created the fan are still active
