Figure F14. Coryell-Masuda diagram for metamorphic clasts from Legs 125 and 195, normalized to chondrites (Nakamura, 1974). Note that Sample 195-1200D-8H, 119–121 cm, shows a different REE (especially LREE) pattern and is very LREE enriched. Such REE abundance levels resemble those of evolved island arc lavas or sediments. The REE pattern of this sample also resembles the slightly enriched LREE patterns of the serpentinite muds (Fig. F8). The REE abundances and patterns for the rest of the metamorphic clasts resemble those of altered oceanic crust from mid-ocean-ridge settings (Kelley et al., 2003).
