The analysis of the mesoscopic structures observed within the Frosolone unit multilayer (Molise region, Central Italy) has led to the distinction of three main «structural groups», each one characterised by different styles of deformation as a response to their lithological features. In this scenario, the Oligo-Miocene Macchiagodena Formation clearly represents the uppermost weakness level of the multilayer, which is mainly made up of Mesozoic and Cenozoic formations affected by less pervasive brittle deformations. Moreover, mesoscopic structures likely related to break-back thrusting sequences have been observed, and might represent an indication of larger scale out-of-sequence thrust propagation occurred in the area.

Abstract
The analysis of the mesoscopic structures observed within the Frosolone unit multilayer (Molise region, Central Italy) has led to the distinction of three main «structural groups», each one characterised by different styles of deformation as a response to their lithological features. In this scenario, the Oligo-Miocene Macchiagodena Formation clearly represents the uppermost weakness level of the multilayer, which is mainly made up of Mesozoic and Cenozoic formations affected by less pervasive brittle deformations. Moreover, mesoscopic structures likely related to break-back thrusting sequences have been observed, and might represent an indication of larger scale out-of-sequence thrust propagation occurred in the area.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
