“…This frame has led many authors (Cello et al, 1997;Cerrina Feroni et al, 2004;Coltorti et al, 1996;Di Luzio et al, 2004;Favali et al, 1993;Ferranti et al, 1996;Frepoli and Amato, 1997;Martini et al, 2001;Pizzi and Galadini, 2009) to note the coexistence of transpression and transtension, which they attributed to several geodynamic models. Our interpretation not only explains this coexistence by a different approach, but also enhances the role assumed by the strike-slip kinematics in the Northern-Central Apennines, similarly to what proposed by Mantovani et al, 2009 andViti et al, 2011 for the central Mediterranean region. In fact our study infers the existence of a geometrically determined tectonic system along the Apenninic Chain and explains the coeval evolution of pop-up structures, pull-apart basins, thrusts, normal faults and oblique to strike-slip faults.…”
