摘要: In the last decade, large geological, geomorphological and pedological mapping projects have been investigating Venetian–Friulian Plain, strongly improving available information about late Pleistocene sedimentary processes. This paper presents an overview of evolution alluvial costal plain since end middle to Lateglacial. was mainly possible through detailed field surveys 20 stratigraphic cores 50–270 m depth. A strong relation between aggrading phases glacial periods (final part MIS 6 Last Glacial Maximum) is evidenced, whereas during interglacial sedimentation occurred in coastal sectors. During Tyrrhenian transgression (MIS 5e) lagoons reached a more landward position than present. The deposits Wurm are represented by thin sequences important depositional hiatus lasted tens thousand years ended around 35–30,000 cal bp. LGM characterized phase deposition until 20,000 bp, then rate lowered Friulian Plain led apical incision systems. Since Lateglacial erosive affected whole brought formation deep wide up present coast.
