From c . 20 Ma there is a southeastward younging in the maximum age of arc volcanism towards the Taupo Volcanic Zone (e.g. Brothers 1984 ). Right lateral displacement along the Vening Meinesz Fracture Zone is inferred to have emplaced

The volcanoes of the active arc front lie immediately west of the Kermadec Ridge in the southern and mid-parts of the arc, then merge with the Kermadec Ridge to the north. The underlying bathymetry (in shaded relief) is derived from the satellite altimetry grid

( Wright et al., 1996 ). Flanking the Havre trough, the remnant Colville Ridge and active Kermadec arc margins form longitudinally continuous ridges. Volcanoes of the Tonga-Kermadec arc front occur within a 40-km-wide zone that extends for ~2,500 km and includes >90 volcanoes ( Worthington, 1999

It is suggested that this area, high on the Colville rim, was a locus of sediment reworking and winnowing because it marked a boundary between two very different basins with different currents and dynamics. This hypothesized comparatively high-energy

Large Proterozoic extension faults, younger than Coppermine basalt, occur in the Colville Hills area, and are possibly related to the 778 Ma Hayhook rifting event documented in the northern Cordillera.
