Figure F3. Age-corrected Nd and ⁸⁷Sr/⁸⁶Sr vs. ²⁰⁶Pb/²⁰⁴Pb for the Leg 192 lavas and tuff (t = 120 Ma) (after Tejada et al., 2004). A, B. Expanded portions of panels on the left. Kw = Kwaimbaita type, Kr = Kroenke type. Fields are shown for previous Kwaimbaita- (Kwaim.) and Singgalo-type basalt from the pre-Leg 192 drill sites, Malaita, and Santa Isabel, and glass from the Nauru and East Mariana basins (data sources: Mahoney, 1987; Mahoney and Spencer, 1991; Mahoney et al., 1993; Castillo et al., 1991, 1994; Tejada et al., 1996, 2002). See Tejada et al. (2002) for data sources for the fields of South (S) Pacific mid-ocean-ridge basalt (MORB), Kilauea, Mauna Loa (subaerial portion), Koolau (subaerial portion), and Mangaia Group islands. The shaded 120-Ma field is for estimated South Pacific mid-ocean-ridge source mantle (see Tejada et al., 2002).
