LGM glacial retreat in the Astico valley and mismatch with the Adige and Brenta glacial transfluences (NE Italy)

Valley glaciers can be fed by transfluence from major glaciers through a gap or a saddle. These glacial systems may be more sensitive to rapid climate changes, in terms of temperature and precipitation rates. Here we present a case study concerning the timing of deglaciation in a Prealpine glacial system connected to transfluences from the Adige glacier. Changes in the position of the end moraines, hosted in the terminal valley reach, are coupled with observation of the glaciofluvial sedimentation in the piedmont area, with special reference to the Astico system, providing new insights on the onset of the glacial decay at the end of LGM.
