Figure F51. Patterns of Ba, Sr, P, Zr, Ti, and Y for the Site U1347 basement samples compared with patterns of ODP Leg 198 Site 1213 basalts (Mahoney et al., 2005), Ontong Java Plateau (OJP) basalts (Kwaimbaita magma type; Tejada et al., 2002; Fitton and Godard, 2004), and normal mid-ocean-ridge basalts (N-MORB) of the southern East Pacific Rise (Hall et al., 2006, and references therein; data adjusted to 8 wt% MgO). Element concentrations are normalized to estimated primitive-mantle (PM) concentrations of Lyubetskaya and Korenaga (2007). Gray band = total range of compositions measured for the Site U1347 holocrystalline samples. A. Pattern of stratigraphic Unit IV holocrystalline basalt (Sample 324-U1347-13R-2 [Piece 3, 52–55 cm]) compared with that of the segregation near the bottom of Unit IV (Sample 324-U1347-13R-6 [Piece 1, 80–83 cm]) and the altered glass from the top of Unit V (Sample 324-U1347-13R-7 [Piece 6, 28–30 cm]). B–F. Patterns of Site U1347 holocrystalline basalts by stratigraphic unit.
