a REE concentrations in gabbro augite from dredges, dives, and drilling at Atlantis Bank normalized to the C1 chondrite values of Anders and Grevesse (1989). Gray field for Atlantis Bank and Segment 19 (Cannat et al. 1999) SWIR basalts is from Johnson and Dick et al. (1992). Pink field for equilibrium liquids is from panel b. b Equilibrium liquids calculated using the REE partition coefficients of Sobolev and Shimizu (1992). Heavy black line is the Hole 735B troctolite from core 83-7. Blue field for Atlantis Bank augite is from panel a. Parental melt representing 5% melting of the hypothetical DMM composition of Workman and Hart (2005) is shown for comparison by the heavy red line
