Concordia diagram for the measured zircons of the transition zone (black for tonalite, red for granodiorite) and of the tonalite sample CMB-4 sedimented into the Como molasse (solid green line) compared to U–Pb radiometric analyses of different minerals (zircons, titanites and allanite) from the literature (dashed ellipses). If not specified in the figures, the ellipses refer to zircon analyses. Literature data are from von Blanckenburg (1989, 1992) and Oberli et al. (2004)
