Guyots in the Southwestern Pacific Basin
Four guyots in a northwest trending group of guyots, 2000 km east of New Zealand, have reliefs of 4200–4500 m and shelf break depths of 700, 880, 900, and 920 m. Blocky and tabular cobbles of olivine basalt and detrital rock were dredged from one of the guyots. The structural province characterized by northwest trending lines of volcanoes has greater extent to the southwest than previously known and comes into contact with the sub-continental Tonga-Kermadec and Fiji structures.
