Figure F3. (A) Depth vs. Na#, (B) depth vs. Mg#, and (C) depth vs. Ni. Open squares = primitive gabbroic rocks (Mg# > 70), solid circles = evolved oxide-rich rocks (Mg# < 70), open diamonds = primitive olivine-rich rocks, squares with cross = evolved rock not enriched in oxides, open square with horizontal line = most evolved rock not enriched in oxides, solid triangles = evolved rock with low V/Sc ratio, solid inverted triangles = evolved oxide-rich rock with low V/Sc, and cross = Sample 176-735B-120R-3, 125-135 cm, with high Mg# compared to Na# and Ca#.
