Abstract

Biserni G., Berendsen J.A.H. and Sandrelli F., Shape reconstruction of the Pleistocene/Holocene unconformity in the
Grosseto alluvial plain (Tuscany, Italy) (IT ISSN 0394-3356, 2004)
One hundred two boreholes were drilled in Grosseto alluvial plain (Tuscany, Italy). Coring evidence shows a sharp lithological change
that is interpreted as a Pleistocene/Holocene unconformity. This suggests the presence of a paleovalley that was eroded by the
Ombrone river during the last glacial interval. Radiocarbon samples and surface’s geometry of lithological changes corroborate this
explanation.
