Figure 2. Simpli fi ed geological map of the study area with sample locations (modi fi ed from Tuller, 2000).
Figure 3. Representative CL images with UePb and LueHf spots of analysed zircons. The UePb ages are reported in Ma as 206 Pb/ 238 U ages for zircons <1000 Ma and 207 Pb/ 206 Pb ages for zircons >1000 Ma with errors at the 2 s level
