Figure F41. Downhole variation of (A) K2O, (B) TiO2, (C) Mg#, (D) Cr, and (E) Zr/Ti in Site U1350 basement. Dashed lines = unit boundaries. Major element data normalized to 100 wt% totals. Mg# = 100 × [Mg2+/(Mg2+ + Fe2+)], assuming that Fe2O3/FeO = 0.15. See "Paleontology" and "Igneous petrology" for description of stratigraphic units.
