Summary:Diagrams of Sc, Th, Sr, Rb show Sc (ranging 2.7-11 ppm) to decrease with increasing differentiation index (D.I.), while Rb (117-149 ppm) and Sr (418-703 ppm) increase. Th (7-16.5 ppm) shows no relationship with D.I. A chondrite-normalized REE pattern shows high fractionation of the light as well as of the heavy REE, with weak Eu anomalies. These results, together with 87Sr/86Sr data from the literature, fit a genetic model in which the Cima di Vila granodiorites are the product of different degrees of melting of a garnet-bearing source rock.
