Figure F4. Chondrite-normalized rare earth element abundances in average basalts from Holes 1136A, 1137A, 1138A, and 1140A (Leg 183) and Hole 747C (Leg 120); Kerguelen and Heard Islands (Storey et al., 1988); Holes 749C and 750B (Leg 120) (Storey et al., 1992; Salters et al., 1992). Normalizing normal mid-ocean-ridge basalt (N-MORB) and enriched mid-ocean-ridge basalt (E-MORB) values are from Sun and McDonough (1989). Is. = island. alk. = alkaline.
