Figure F8. Chondrite (Sun and McDonough, 1989) normalized rare earth element (REE) abundances of the pool samples recovered from Expedition 309/312. REE patterns are shown for each sublithology. Almost all samples show normal mid-ocean-ridge basalt (N-MORB) REE patterns. However, one lava sample from the sheeted and massive flows and two samples from upper dikes show light rare earth element–enriched patterns. A late dike sample from the bottom of Hole 1256D has evolved values. Red lines = N-MORB pattern (Sun and McDonough, 1989), gray lines = REE abundances from 0°–10°N on the East Pacific Rise (PetDB).
