Figure F67. Primitive mantle normalized Zr/Ti vs. Zr for Site 1138 basalts (upper series = solid diamonds; lower series = shaded diamonds) compared with data for other central and southern Kerguelen Plateau basalts. The upper series lavas are between Site 1136 and 1137 basalt (Zr/Ti)_N values and may represent parental compositions for the lower series lavas. Site 1136 basalts = small shaded circles; Site 1137 basalts = large shaded circles.
