Abstract
The Calabrian-Peloritan Arc includes three Paleozoic sequences showing an analogous metamorphic evolution, characterized by a unique greenschist phase with low to medium-low pressures. The Bocchigliero sequence (Sila), considered typical of the area, was chosen to study the metamorphism and its age. The geological, petrological and geochronological data consistently indicate that the sequence suffered only the Hercynian metamorphism dated 328-330 Ma; no traces of Caledonian or Alpine metamorphism were found. In addition, geochemical data confirm the Paleozoic evolution of the Bocchigliero basin (presented already in a previous work), which in Cambro-Ordovician underwent maximum extension and witnessed subsequent uprising of basaltic magmas from the crust-mantle boundary, and later upwelling of andesitic and rhyolitic magmas derived from crustal melts originated at different depths.
