Figure 11. Chondrite-normalized trace element distribution in the products of the partial (a, c) and fractional (b, d) melting of enriched metasomatized mantle having a composition of amphibole- and phlogopite-bearing garnet peridotite Ol0.59 + Opx0.20 + Cpx0.08 + Grt0.08 + Phlog0.02 + Amph0.03. The thick line is the average composition of the primary magmas of the Kola alkaline province, the shaded line denoting the composition of the alkaline-ultramafic and phonolite series. The thin lines are the model compositions of the melts and complementary restites (broken lines) for the 0.1-5% degrees of melting. The normalizing factors used were after Evensen et al. [1978] for these and after Hofmann [1988] for the other elements.
