In its western edge, it is characterized by the close association of continental units<br>deformed under high-pressure metamorphic conditions (Lower Units) and oceanic units showing a metamorphism ranging from high-pressure (Schistes Lustrés<br>Complex) to very low-grade conditions (Upper Units). This paper provides a complete review of the relationships between the continental and oceanic<br>units in selected five areas where the stratigraphic features, deformation history, metamorphic P-T path and tectonic setting are available for each unit. The<br>collected data indicate that the oceanic units occur not only at the top of the continental ones, as generally proposed in the literature, but also intercalated within<br>them. Such relationships were achieved at shallow structural level during the late stage of exhumation, when the continental units were tectonically coupled<br>with the oceanic units which were dragged as slices from the orogenic wedge. The coupling probably occurred immediately before the transition from syn- to<br>post-orogenic geodynamic regime that affected the whole Alpine-Apennine collisional system in the early Oligocene. After the coupling, the stack of oceanic<br>and continental units experienced a further exhumation-related deformation before their final exposure at the surface.</p> ER -
