Petrochemical classifications and characteristics of the studied mafic rocks. a TiO2 vs. Al2O3 diagram (Pearce 1983) showing the discrimination between basaltic liquids and cumulate. b Total alkali vs. Silica diagram of Le Maitre et al. (1989) with subalkaline–alkaline fields after Miyashiro (1978) displays the compositional range of the magmatic protoliths. c Zr/TiO2 × 0.0001-Nb/Yb classification diagram. d Mg# vs. SiO2/Al2O3 diagram showing both the field of tholeiitic and alkali differentiation trends (Irvine and Baragar 1972) and mineral fractionation (after Kempton and Harmon 1992)
