From: Geochemical characterization of oceanic basalts using Artificial Neural Network
(a) The variation of Ce/Y-Zr/Nb ratio of the CIOB basalts mostly falls in the SEIR domain and indicates a genetic relation. In comparison, the basalts from Ninetyeast Ridge and Site 215 [30] do not show any relation with the CIOB basalts. (b) La/Yb-Zr/Nb ratios show a clustering and most of the data fall in the SEIR segment whereas Ninetyeast Ridge and Site 215 [30] again are not related with the CIOB basalts. (c) (La/Sm)N-Zr/Nb binary mixing diagram indicates that the CIOB basalts are mainly N-MORB with some component of E/P-MORB. For comparison data from Site 215 and Broken Ridge [29, 30] have been plotted.
