Figure F7. Distinct geochemical characteristics of volcanic rocks from the Kyushu-Palau Ridge (KPR)/Daito Ridge intersection (modified from Ishizuka et al., 2011b). Pb isotopes clearly discriminate volcanic rocks of this area from other KPR volcanics. EM-1, enriched mantle 1, EM-2 = enriched mantle 2, MORB = mid-ocean-ridge basalt, PSP = Philippine Sea plate, OIB = ocean-island basalt, HIMU = high µ (238U/204Pb).
