Post-LGM valley fills from the northern coast of Tuscany: depositional facies and stratigraphic architecture

The stratigraphic architecture of three adjacent valley bodies of post-LGM age buried beneath the northern coast of Tuscany is illustrated in detail. Above a gravel fluvial deposit, the valley fills exhibit a distinctive succession of coastal plain to estuarine facies, punctuated by an aggradational stacking pattern of millennial-scale depositional cycles with distinctive climatic signature. Radiocarbon dates document that the three valleys were active simultaneously and that rapidly created accommodation during transgression was filled under conditions of very high sediment supply
