THE FOGLIA RIVER ALLUVIAL SYSTEM (NORTHERN MARCHE) AND ITS RELATION TO THE LATE QUATERNARY EVOLUTION OF THE CENTRAL ADRIATIC SHELF

Abstract

The late Quaternary evolution of the mid-adriatic continental shelf and the river Foglia (Northern Marche) related sediments have been chosen as an example for a tentative correlation between marine and continental sequences.
The stratigraphic setting of the late Quaternary deposits of the Adriatic shelf has been defined by many Authors and is characterized by a low system tract, present inside the mid-adriatic depression, followed by the transgressive and highstand system tracts formed by the post-glacial sea-level rise.
Taking into account data from numerous available boreholes, a longitudinal section of the Foglia river alluvial plain has been defined
that shows four depositional units. These units, supported by radiocarbon ages, correlate with the recognized marine system tracts (I –
II = LST; III = TST; IV = HST).
