Heavily outlined fields encompass data for ODP Site 807 basement Unit A and Sites 803 and 807, Units C-G. Data for the Site 289 basalt lie in the latter field. Data fields for the Manihiki Plateau (for dredged and DSDP Site 317 lava flows), Nauru Basin, Pacific midocean-ridge basalts (MORB), the Koolau and Kilauea volcanoes of Hawaii, and the Mangaia Group islands of the South Pacific are shown by light outlines (from Tejada et al., 2000).
