Abstract

The Quaternary basins of the axial zone of central Apennines represent a key areas for a better understanding of the morphotectonic evolution of this sector of the chain, during the Pleistocene times. In the axial zone of the Umbria-Marche Apennines are preserved several fault-bounded intramontane basins, formed at the end of Lower Pleistocene. These basins was raised by Pleistocene tectonic uplift and subsequently some of them were partially incised by fluvial network. In order to improve the knowledge on the evolution, and the extinction of these basins, morphotectonic features, such as relicts of ancient and more recent planation surfaces and drainage network arrangements, have been correlated to the distribution of the master faults which controlled the development of the intramontane basins of Umbria-Marche sector. Gravimetric measures produced in the basins have allow us to reconstruct the arrangement in the depth of the sedimentary top of bedrock, and to evaluate the thickness of the Quaternary clastic infill of basins.
