Topography and Heat Flow of the Fiji Plateau

Abstract

THE Fiji Plateau is an extensive region at a depth intermediate between continent and ocean basins. Above it rise the islands of Fiji where acidic plutonio rocks occur within an ocean basin in a tectonic setting wiiich can only be compared with the granitic Seychelles Islands in the deep western Indian Ocean. The results of the few seismic refraction lines run on the plateau indicate a variable crust of intermediate thickness1. Thus the Fiji Plateau is an unusually interesting and promising region for tectonic studies. In the spring and summer of 1967, the Scripps Institution of Oceanography expedition Nova studied this region. In this preliminary communication we discuss results in topography and heat flow and suggest a relationship between them.
