AB: The Roveto Valley area is part of a segment of the Apennine chain, which was intensively deformed by Neogene-Quaternary compressional and extensional tectonics. This sector of the chain mostly formed in Neogene times in the context of the eastwards piggy-back propagation of the thrust system. Geomorfologically, the Roveto Valley is a narrow and elongated -trending morphological depression, bounded by some of the most relevant regional tectonic features of the whole Apennines, such as the Simbruini-Ernici Mts. basal (leading) thrust and the Val Roveto-Atina-Caserta line. Continental Plio-Quaternary deposits (alluvial-fan conglomerated and sands) locally tilted, are clear geomorphic markers and outcrop at different topographic elevations. These sedimentary bodies constitute a morpho-lithostratigraphic succession linked to the local tectosedimentary setting. These sediments do not contain materials suitable for biochronological determinations, as is often the case for most the central Apennines continental deposits. Therefore, to determine the chronology of the Roveto valley deposits and to assert the acquisition time with respect to the tectonic tilting, four different units of the morpho-listhostratigraphic succession were sampled for magnetostratigraphic investigations. A better assessment of the tectonic Quaternary evolution of the Campoli Appennino sector has been achieved by the integration of paleomagnetic data with stratigraphic, morphological and tectonic features.
