Heavily altered (argillic alteration) dacitic ignimbrite, overlain by the basal layers of the Tortonian-Messinian sedimentary sequence. A large part of the outcrop is covered by colluvium (which here forms surfaces resistant to erosion, due to the presence of caliche) and by a thin veneer of unstable debris (which at times can be completely washed off by large storms).
