Figure 1. Predicted bathymetry (after Smith and Sandwell, 1997) of the Ontong Java Plateau showing the locations of sites drilled on Leg 192. Solid stars = sites penetrating lava sections. Open star = Site 1184, where a volcaniclastic sequence was recovered. Solid circles = previous ODP and DSDP drill sites that reached basement. Open circles = Site 288, which did not reach basement but bottomed in Aptian limestone, and Site OJ-7, which was proposed for Leg 192 but not drilled (see text). The bathymetric contour interval is 1000 m.
