Figure F42. Cr vs. TiO2 for basalts from all ODP drill sites on the Ontong Java Plateau (Mahoney et al., 1993; this volume). Data fields for the Kwaimbaita and Singgalo Formations of Malaita are shown for comparison (Tejada et al., in press). Data for Site 1186 cover a similar range to those for Site 1183 and fall within the field of the Kwaimbaita Formation.
