Representation of the three main magmatic components (big squares) and mixing models (lines) as defined by Di Renzo et al. 2011. CI component as defined by D’Antonio et al. 1999 is not reported as end-member, but it can be individuated by the clustering of triangle datapoints. Lines were obtained using a binary mixing model by the hyperbolic equation Ax + Bxy + Cy + D = 0 (Langmuir et al. 1978). The two mixing curves between the NYTc and Mic consider different Sr concentrations for the NYTc, i.e., 250 and 700 ppm, respectively. Error bars are smaller than datapoints. Modified after Arienzo et al. 2016
