“Two-way Stretch” of Sialic Crust and Plate Tectonics in the South-west Pacific

Nature volume 226, pages 741–742 (1970)Cite this article

Abstract

ANALYSES of seismic and continuous gravity measurements over the northern Tasman Sea1 have confirmed the existence of “quasi-continental” crust (20–26 km thick) beneath the parallel ridges—Norfolk Ridge, Lord Howe Rise and Dampier Ridge—that extend north-westward from New Zealand (Fig. 1). The intervening major trough, New Caledonia Basin, is shown to have a floor of true oceanic thickness (9 km).
