Fig. 3

Selected zircon crystals of augen gneisses showing internal structures and spot ages. Statistically significant cluster U–Pb ages, Th–U contents and Th/U ratios are also indicated in a, b and c. In c REE pattern of zircon dated 544 Ma is reported (dotted circle indicates the analysed site). SEM images (cathodoluminescence detector) and data ages of zircons derive from Micheletti et al. (2007)
