Figure F53. TiO2 vs. (A) Sr, (B) Ba, (C) P2O5, and (D) Y for Site U1372. Note that Expedition 330 major element data are normalized to 100 wt% totals. Data for dredged samples from the Louisville Seamount Trail include only samples with LOI < 6 wt% (data of Hawkins et al., 1987; Vanderkluysen et al., 2007; Beier et al., 2011). Fields for several Hawaiian volcanoes are shown. “Hawaii shield” fields are for Mauna Kea (blue line), Mauna Loa (green line), and Kilauea (red line) (data of Lipman et al., 1990; Frey et al., 1991; Moore and Clague, 1992; Clague et al., 1995; Rhodes and Hart, 1995; Garcia et al., 2003). “Hawaii postshield” fields include Lapahoehoe and Hamakua lavas (data of Frey et al., 1990; West et al., 1988). Also shown are fields for the southern East Pacific Rise (EPR; data of Sinton et al., 1991; Bach et al., 1994; Mahoney et al., 1994) and Ontong Java Plateau (OJP; data of Tejada et al., 1996, 2002; Fitton and Godard, 2004).
