Figure 9. Multi-element diagrams for chondrite-normalized REEs (Boynton, 1984) and for incompatible elements normalized to primitive mantle (Hofmann, 1988). A. Data for Alboran basalts and basaltic andesites. (Continued next page.)

Figure 9. Multi-element diagrams for chondrite-normalized REEs (Boynton, 1984) and for incompatible elements normalized to primitive mantle (Hofmann, 1988). A. Data for Alboran basalts and basaltic andesites. B. Data for Alboran andesites, dacites, and rhyolites. Average normal MORB (N-MORB; Hofmann, 1988), ocean island basalts from Saint Helena (Chaffey et al., 1989) and Gomera (S. Dorn and K. Hoernle, unpubl. data), and Aeolian Arc (Salina) basalts, andesite, dacite, and rhyolite (Ellam et al., 1989) are shown for comparison.
