The tectono-stratigraphic evolution of the Fucino Basin (central Apennines, Italy): new insights from the geological mapping of its north-eastern margin.

We present the geological map of north-eastern margin Fucino Basin, which is mainly characterized by Plio-Quaternary continental deposits that show transition from deeper-water lacustrine environment, marginal system, and fluvial facies. These unconformably overlie upper Messinian Lago-Mare sediments pre-orogenic carbonate succession. The occurrence Caspiocypris tiberina in sediments, coupled with normal magnetic polarity Casa Colombaia section, led to suggest onset sedimentation these late Piacenzian (2.58–3.04 Ma). are ostracod assemblages related Loxocorniculina djafarovi zone, pointing last event Salinity Crisis (5.40–5.33 This new stratigraphic framework may be useful refine long-term slip rates still active faults affect Basin.
