Abstract
The southern Apennine is the segment of the circum-Mediterranean orogenic system between the central Apennine to the North and the Calabria-Peloritani arc to the South, bounded by the Ortona-Roccamonfina and the Sangineto tectonic lines respectively. It consists in a salient: north-east verging thrust and fold belt, interposed between the back-arc Tyrrhenian basin to the West and the undeformed Apulian-Adriatic foreland to the East. Its present Structural setting is the result both of mainly compressive tectonic events, related to the subduction followed by the roll-back of the Adria plate, and of the extensional tectonics related to the opening, since the late Miocene, of the Tyrrhenian sea (MALINVERNO & RYAN, 1986; PATACCA & SCANDONE, 1989; DOGLIONI, 1991). Aiming to Point Out the space-time migration of the deformation, a geological map of the area between the Ortona-Roccamonfina tectonic line to the North and the Maratea-Val d'Agri alignment to the South showing the possible kinematic units of the southern Apennine has been elaborated. The above area includes the whole Campania and part, of Lucania, Molise and Puglia regions. A kinematic unit can be defined as a stack of tectonic units (or even only one), eventually covered with thrust top deposits, that piled Lip during the same tectonic event and afterwards behaved like an unique geological body in respect to more external areas.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
