Overview and Principal Results of the Second Leg of the First Joint CCOP/SOPAC-Tripartite Cruise of the R/V Kana Keoki: North Fiji Basin Survey (KK820316 Leg 03)

  • Chapter
Basin Formation, Ridge Crest Processes, and Metallogenesis in the North Fiji Basin

Abstract

The North Fiji Basin (Figure 1) is an active dilational backarc basin bordered by the Vitiaz Trench to the north, the Lau basin to the east, the Hunter Fracture zone to the south, and the New Hebrides arc and trench to the west. It is the site of a complex accretionary plate boundary that includes at least one R-R-R triple junction. The geological framework of the North Fiji Basin, the configuration of its bounding arcs and trenches, and its relationship to the Fiji Islands have engendered considerable interest for almost two decades. Early workers speculated on the significance of the anomalous heat flow in the North Fiji Basin (Sclater and Menard, 1967), the geotectonic position of Fiji (Dickinson, 1967), the regional seismicity (Isacks et al., 1969), and the petrologic variations across Fiji (Gill, 1970).
