Collectively, the granitoids show a relatively restricted Sri composition, from 0.7095 to 0.7123, and a much larger variation in the initial Nd composition with εNd values that, although mostly lower than − 6, range from − 0.3 to − 10.1 defining a peculiar vertical array, as already pointed out by Rottura et al. (1990). The less negative εNd values overlap those of quartz gabbros from the Palmi–Bagnara area (Rottura et al., 1989), that Purmorphamine are in turn characterized by distinctly less radiogenic 87Sr/86Sr initial ratios. Interestingly, while the Sri values of the granitoids appear broadly related to the rock composition, with the quartz diorites, tonalites and BAG having the lowest values and the BMG and BMPG the highest, respectively, the εNd variations appear largely unrelated, with values spreading widely also within the same rock type. The largest variations are cork cambium observed in the CVP tonalites (εNd from − 0.3 to − 8.0) and in the CVP two-mica porphyritic granitoids (εNd from − 1.2 to − 10.5), while quartz diorites and especially BMG and SM, two-mica porphyritic granitoids, are characterized by relatively more homogeneous Nd isotopic compositions (mostly from − 7.20 to − 8.10).
