IL SOVRASCORRIMENTO DI NARNI (APPENNINO CENTRALE)

Abstract

Structural analysis carried out in the Umbrian pre-Apen­nines allowed us to characterize the Narni thrust. It is defined by two NW-SE trending thrust planes which develop a tecton­ic element, made of overturned pelagic sequence, organized in a sort of duplex and localized between the hangingwall and the footwall. The roof thrust, evidenced by the Calcare Massiccio, shows a tip line at the core of the overturned Narni an­ticline hangingwall and is most probably a blind thrust. [...]
