Discrimination diagrams for the basaltic volcaniclastics and rhyodacite tuff from Mt. Ivanščica. A Th – Nb/16 – Hf/3 diagram (Wood, 1980). A = normal mid-ocean ridge basalts (N-MORB); B = enriched MORB (E-MORB) and within-plate tholeiites (WPT); C = alkaline within-plate basalts (AWPB); D = calc-alkali basalts (CAB); E = island-arc tholeiites (IAT). B Yb – Th/Ta diagram for felsic and intermediate rocks (Gorton & Schandl, 2000). C La/Yb – Th/Nb diagram (Hollocher et al., 2012). D FeO – Al2O3 – MgO discriminant diagram for pyroxene (Le Bas, 1962)
