a Th/La ratio versus the Sm/La ratio redrawn from Tommasini et al. (2011). SALATHO = assumed reservoir with certain Th/La and Sm/La ratios; UC upper crust. In addition data from the Bergell pluton (calc alkaline evolution, von Blanckenburg et al. 1992); basaltic-andesitic dykes (Venturelli et al. 1984; Conticelli et al. 2009); Val Cervo Pluton (Bigioggero et al. 1994) are shown (b). REE pattern of the different groups of alkaline and calc-alkaline evolution in the Alps. Bold line average of ultrapotaasic dykes of Conticelli et al. 2009; black thin line average of basaltic/andesitic dykes (Conticelli et al. 2009); black stippled line Travesella diorite (Van Marcke de Lumen and Vander Auwera 1990); grey thick line Bergell tonalite (von Blanckenburg et al. 1992); grey thin line Bergell basalt (von Blanckenburg et al. 1992)
