Figure 4

(a) Variation of the chondrite-normalized Dy/Yb versus Ce/Yb of the basalts from the Hirondelle Basin (HB) flank in comparison to those from the young volcanoes of the Terceira Rift; (b) Variation of (Dy/Yb)N versus SiO2 contents of the older basalts from the HB flank to the young lavas. Note that the basalts from D. João de Castro seamount have higher SiO2 but lower (Dy/Yb)N than the HB basalts. Data sources as in Fig. 3.
