a Y/Zr plot used for discrimination of magmatic affinity (after MacLean and Barrett 1993). Th/Yb vs. Ta/Yb discrimination diagram (Pearce 1982). Values for N-MORB, E-MORB, and oceanic-island basalt (OIB, within-plate basalt) are from Sun and McDonough (1989). Figures indicate Zr/Y ratios. b Discrimination plots of Nb/Th vs. Nb and c TiO2/Yb vs. Nb/Yb (after Pearce 2014). Primitive Mantle composition is from Hofmann (1988), Continental Crust, MORB (Mid-Ocean Ridge Basalts), OIB (Ocean-Island Basalt) and Arc Volcanics from Schmidberger and Hegner (1999)
