Figure F66. Major element compositional variations for Site 1138 compared with other Kerguelen Plateau sites. The TiO₂ and Fe₂O₃ enrichments in the lower series basalts (shaded diamonds) are the most extreme in the province, whereas Al₂O₃/CaO of Site 1138 basalts are comparable to those of Sites 747 and 749 basalts, but generally higher than those of basalts from Sites 1136 and 1137.
