From: Continuity in geochemistry and time of the Tertiary Bergell intrusion (Central Alps)
a Schematic geological-tectonic map of the Central Alps (modified after Trommsdorff and Nievergelt 1983). Black stars represent locations of literature dated samples for the Tertiary intrusions (Bergell and Novate). For the Gruf complex and the Adula-Cima Lunga Nappe the age of migmatization is also given. b Transition zone in upper Valle dei Ratti around Rifugio Volta (Province of Sondrio, Italy). Black stars represent samples dated in this study
