On the NE margin of Mount Etna, near the town of Fiumefreddo, previously undescribed exposures reveal a thrust contact between Cretaceous-Eocene 'argille scagliose' of the Apennine-Maghrebian Chain and underlying sediments of Lower Pleistocene age. The thrust plane is well exposed, strikes WNW-ESE, and shows compressive movements towards the N-NW. These exposures document a late phase of shortening in the chain, occurring near the end of the Lower Pleistocene, maybe in Middle Pleistocene times. This tectonic phase was previously attributed to the Lower Pleistocene (Gela nappe).
