Figure F5. Compositions of clinopyroxene plotted against depth. These represent separate 10-point 10-µm spot-size contiguous traverses of the cores and rims made by H. Dick for Leg 176 samples. Similar data for the upper 500-m section do not exist. Solid symbols = core composition, short vertical bars at the ends of the tie lines = rim compositions. A. Molecular Mg x 100/(Mg + Fe) with all iron as FeO. B. Na2O. C. TiO2. D. Cr2O3.
