Structural analysis of the Triassic siliciclastic Verrucano sequence of the Pisani Mounts (northern Apennines) revealed the presence of two main ductile deformation pahses: an earlier deformation phase (D1), attributed to continental collision, followed by a second deformation phase (D2) related to the tectonic collapse of the tectonic units. The D1 phase is characterized by F1 folds, sometimes cleavage transected, by an S1 penetrative axial plane foliation and by a stretching lineation L1, that is parallel to F1 fold axes. Structural analysis and finite strain determinations allow the authors to discuss some models that could explain this parallelism in the Pisani Mounts
