Evolution of an Alpine fluvioglacial system at the LGM decay: The Cormor megafan (NE Italy)

Sedimentary evolution and persistence of open forests between the south-eastern Alpine fringe and the Northern Dinarides during the Last Glacial Maximum

“…This event was likely related to a contemporary entrenchment of the glacier outwash supplying the Soča megafan in the early phases of the ice decay. A similar evolution was observed in the Tagliamento megafan and dated at 19.5 cal ka BP (Fontana et al, 2014a). A late clayey colluvial deposition with the development of hydromorphic soils was dated at 12.7 cal ka BP, suggesting a phase of colluvial production from the surrounding slope of the Karst.…”

“…The Soča megafan merged with the large LGM glacio-fluvial systems in the eastern Friulian Plain, which are mostly related to the Tagliamento system ( Fig. 1; Fontana et al, 2010Fontana et al, , 2014aMonegato et al, 2007).…”

The modeling of archaeological and geomorphic surfaces in a multistratified urban site in Padua, Italy

“…In Padua and the surrounding alluvial plain, the fluvial sediments deposited during the Last Glacial Maximum (LGM) were cut at the end of the glaciation by incised valleys with a depth of 10–15 m (Mozzi, Ferrarese, & Fontana, ). The same erosive phase occurred in the nearby Piave and Tagliamento megafans (Carton et al., ; Fontana, Mozzi, and Bondesan, , ; Fontana, Monegato et al., ), and other megafans along the southern Alpine piedmont (Fontana, Mozzi, & Marchetti, ). As for the study area, these valleys were completely filled by Brenta River sediments during the latest Pleistocene and early to middle Holocene, resulting in the present low‐gradient alluvial landscape (Cucato et al., ; Mozzi et al., 2010; ).…”

Glacier variations in the European Alps at the end of the last glaciation

“…Ravazzi et al (2014) suggest LGM Sarca glacier collapse in the Garda Lake region was underway by 17.7 and 17.2 ka cal BP. Dating of the timing of shutdown of sediment delivery to the distal outwash plain in the Friuli region at around 20.4 to 19.5 ka delineates the moment of withdrawal of the Tagliamento glacier from the LGM moraine complex (Fontana et al, 2014b). Along the southern forelands a similar timing for cessation of delivery of glaciofluvial sediments to megafans and the onset of incision into fan deposits is noted (Carton et al, 2009;Fontana et al, 2014a).…”
