Abstract: Structural, metamorphic and geochronological data from the Valle del’Orco are best explained by an orogenic wedge model in which crustal slices from continent and ocean acted as passive blocks at diVerent times in the Alpine orogeny. Deformation generally migrated westwards in this section, and metamorphic recrystallization at any given point was largely controlled by the pervasiveness of strain. The data suggest a dynamic crustal stacking system lasting from 70 to 35 Ma, rather than continental collision following long-lived B-type subduction, and oVer a relevant and simple model for eclogite exhumation that requires exumation of ductile shear-bounded slices within the orogenic wedge. The easternmost, internal unit of the Sesia-L...
