DOMINI IN COMPRESSIONE ED IN DISTENSIONE AL RETRO DEI FRONTI DEL GRAN SASSO - M. PICCA E DEL M. MORRONE: IL RUOLO DELLA ZONA DI TAGLIO AVEZZANO - BUSSI (APPENNINO CENTRALE)

Abstract

The centrai Apennines are characterized by the occur­rence of a wide domain of carbonate platform (Lazio - Abruz­zi units), which overlies tectonically a belt of platform-to­basin, Mesozoic-Tertiary units (Gran Sasso - Mt. Genzana belt). This tectonic edifice overrides the basinal sequences of the Marche and Villadegna - Cellino units, and the Morrone and Mt. Maiella - Casoli outer domains along a leading fron­tal are, convex to the NNE, with an E-W overthrust segment (Gran Sasso - Mt. Picca), and a N-S transpressive, right-lateral segment (Rigopiano - Bussi). The footwall of the whole stack is the Adriatic foredeep-foreland system. [...]
