The geological evolution of New Caledonia may be divided into three phases. The Gondwanan phase (Permian-Early Cretaceous), is marked by subduction along the SE Gondwaland margin. At that time, proto-New Caledonia was located in a fore-arc region in which volcanic-arc detritus accumulated; whilst accretion and subduction of oceanic and terrigenous material formed an accretionary complex metamorphosed into the blueschist facies. During the Late Cretaceous-Eocene, marginal rifting isolated New… Expand
Permian rifting and isolation of New Caledonia: Evidence from detrital zircon geochronology
The island of New Caledonia is the second largest rock exposure of the continent Zealandia. The New Caledonian basement rocks have been interpreted as representing a late Paleozoic to MesozoicExpand
Chapter 3 Pre-Late Cretaceous basement terranes of the Gondwana active margin of New Caledonia
Abstract The basement under the Late Cretaceous unconformity in New Caledonia consists of three amalgamated terranes. They are all oceanic, arc-related and developed offshore from the easternExpand
Chapter 2 Geodynamics of the SW Pacific: a brief review and relations with New Caledonian geology
Abstract The SW Pacific region consists of a succession of ridges and basins that were created by the fragmentation of Gondwana and the evolution of subduction zones since Mesozoic times. ThisExpand
Upper Cretaceous to Palaeogene successions of the Gouaro anticline: Deepwater sedimentary records of the tectonic events that led to obduction in New Caledonia (SW Pacific)
Abstract In New Caledonia, upper Cretaceous to Palaeogene sedimentary rocks record a regional tectonic shift from Cretaceous extension to Eocene compression, which led to the obduction of oceanicExpand

A Reappraisal of the Poya Terrane (New Caledonia): Accreted Late Cretaceous‐Paleocene Marginal Basin Upper Crust, Passive Margin Sediments, and Early Eocene E‐MORB Sill Complex
The Poya Terrane of New Caledonia is a composite lithotectonic unit made of (i) Campanian-Paleocene enriched mid-ocean ridge basalt (E-MORB) and BABB-type (back-arc basin basalt) basalts and abyssalExpand
Evolution and sedimentation in a forebulge environment: example of the late Eocene Uitoé Limestone, New Caledonia, Southwest Pacific
New litho- and biostratigraphic data for the Uitoé Limestone on the southwest coast of New Caledonia constrain its age to the E13–E15 zone (late middle–late Eocene or late Bortonian–Runangan in theExpand
Chapter 4 Late Cretaceous to Eocene cover of New Caledonia: from rifting to convergence
Abstract In New Caledonia, the cover refers to the autochthonous Late Cretaceous to Paleogene sedimentary and volcanic formations unconformably overlying the basement rocks and underlying theExpand
Cretaceous fore-arc basalts from the Tonga arc: Geochemistry and implications for the tectonic history of the SW Pacific
The Tonga fore-arc preserves a complex history of subduction initiation, back-arc basin formation and arc volcanism which has extended from the Cretaceous to the present. In this paper, we discussExpand
