Summary:Lithologies analysed include granodiorites, diorites, amphibole gabbros and norites. The intrusions of this area form a composite Hercynian pluton with abundant basic and intermediate lithologies, characterized by hydrous minerals amphiboles and biotites. Emplacement site levels were controlled by P of approx 4 kbar. Corona textures indicate a post-tectonic emplacement. Geochemical data indicate an orogenic affinity; basic lithologies show mantle- crust interaction. Gabbros have an Rb/Sr isotopic signature nearer crustal values with respect to diorites and E granodiorites. The composite nature of the pluton is indicated and formed through intrusion of distinct magmas forming the Rovale norites and amphibole gabbros, the Case Nocelle Sottana gabbro, diorite, tonalite and possibly the E granodiorite and N granodiorite.
