... Fiji Basin respectively, and by a complex set of transform faults (Fig. 1; Hamburger & Isacks 1988). Magmatism in Fiji was mainly related to subduction along the now inactive, southwest-dipping Vitiaz subduction zone (Fig. l ) , which was disrupted in the early Pliocene or late Miocene (Gill & Whelan...

The gold mineralization in both deposits is spatially and genetically related to monzonite intrusions and to a low...

... of the Samoan Islands, where it turns nearly east–west and is known as the Vitiaz Lineament ( Fig. 1 ). Of particular note is that Koppers et al . ( 2008 ) showed that samples dredged from the deep submarine flanks of Savai'i yield very much older ages than found for the youthful volcanism that dominates...

... of Viti Levu, Fiji, on the southwest margin of the shoshonitic Tavua caldera ( Fig. 2 ). Viti Levu was once part of the now inactive Vitiaz Arc that occurred on the margins of the Indo-Australian and Pacific plates. This arc was active from the Early Eocene to Middle Miocene. The Tavua caldera ( Fig. 3...
