...A. J. De Feyter; N. Molenaar Abstract During the late Miocene, in the central Italian Apennines, sedimentation occurred in a few distinct basins resulting from synsedimentary tectonics. Alluvial fan sediments of the Messinian Colombacci Formation accumulated in the most western of these basins...

In particular, petrographic data indicate that the sandstones used in the historical buildings of Urbino, come from the arenitic lithofacies of the Messinian p.p. Colombacci...
