Abstract Starkly contrasting tectonic reconstructions have been proposed for the Late Cretaceous to mid Eocene (~ 85–45 Ma) evolution of the southwest Pacific, reflecting sparse and ambiguous data. Furthermore, uncertainty in the timing of and motion at plate boundaries in the region has led to controversy around how to implement a robust southwest Pacific plate circuit. It is agreed that the southwest Pacific comprised three spreading ridges during this time: in the Southeast Indian Ocean… Expand
Cretaceous to present-day tectonic reconstructions of Zealandia
Reconstructions of the past relative positions of northern and southern Zealandia provide important constraints on the orientation and amount of strain accumulated between rigid plates within theExpand
Widespread compression associated with Eocene Tonga-Kermadec subduction initiation
Eocene onset of subduction in the western Pacific was accompanied by a global reorganization of tectonic plates and a change in Pacific plate motion relative to hotspots during the period 52–43 Ma.Expand
The Late Cretaceous to recent tectonic history of the Pacific Ocean basin
Abstract A vast ocean basin has spanned the region between the Americas, Asia and Australasia for well over 100 Myr, represented today by the Pacific Ocean . Its evolution includes a number of plateExpand
Reconstruction of subduction and back-arc spreading in the NW Pacific and Aleutian Basin : clues to causes of Cretaceous and Eocene plate reorganizations
The Eocene (~50–45 Ma) major absolute plate motion change of the Pacific plate forming the Hawaii‐Emperor bend is thought to result from inception of Pacific plate subduction along one of its modernExpand
Geodynamic reconstruction of an accreted Cretaceous back-arc basin in the Northern Andes
Abstract A complex history of subduction, back-arc basin formation, terrane accretion and transpressional shearing characterizes the evolution of the Caribbean and northern South American marginExpand
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
Continental-scale geographic change across Zealandia during Paleogene subduction initiation
Data from International Ocean Discovery Program (IODP) Expedition 371 reveal vertical movements of 1–3 km in northern Zealandia during early Cenozoic subduction initiation in the western PacificExpand
Ocean Basin Evolution and Global-Scale Plate Reorganization Events Since Pangea Breakup
We present a revised global plate motion model with continuously closing plate boundaries ranging from the Triassic at 230 Ma to the present day, assess differences among alternative absolute plateExpand
Melanesian back-arc basin and arc development: constraints from the eastern Coral Sea
Abstract The eastern Coral Sea is a poorly explored area at the north-eastern corner of the Australian Tectonic Plate, where interaction between the Pacific and Australian plate boundaries, andExpand
Southward propagation of Nazca subduction along the Andes
The model suggests that Nazca subduction has not been fully continuous since the Mesozoic but instead included episodic divergent phases, and it is found that foredeep sedimentation and the initiation of Andean compression are both linked to interactions between the Nazca slab and the lower mantle, consistent with previous modelling.

A Late Cretaceous and Cenozoic reconstruction of the Southwest Pacific region: Tectonics controlled by subduction and slab rollback processes
Abstract A Cenozoic tectonic reconstruction is presented for the Southwest Pacific region located east of Australia. The reconstruction is constrained by large geological and geophysical datasets andExpand
Late Cretaceous to recent plate motions in western South America revisited
The Andean Cordillera has evolved since the Late Cretaceous in the context of subduction of oceanic lithosphere beneath continental lithosphere, making the kinematics between South America and itsExpand
Late Cretaceous−Cenozoic tectonic development of the southwest Pacific region
Abstract A new model of the plate tectonic development of the southwest Pacific integrates the continental geology of New Zealand with the age structure of the surrounding oceanic crust revealedExpand
Revised Eocene‐Oligocene kinematics for the West Antarctic rift system
Past plate motion between East and West Antarctica along the West Antarctic rift system had important regional and global implications. Although extensively studied, the kinematics of the rift duringExpand
Revised tectonic evolution of the Eastern Indian Ocean
Published plate tectonic models for the Australian-Antarctic plate pair imply geologically improbable scenarios at either, or both, ends of the Cretaceous rift and spreading system. Controversy alsoExpand
Evolution of the eastern Indian Ocean since the Late Cretaceous: Constraints from Geosat altimetry
We propose a new model for the tectonic evolution of the eastern Indian Ocean from the Late Cretaceous to the present. Two types of data are used to improve previously published reconstructions.Expand
Tectonic evolution of the southwest Pacific using constraints from backarc basins
We present a revised model for the formation of southwest Pacific backarc basins from 120 Ma to the present day. Our aim is to improve our understanding of the tectonic regime operating in the regionExpand
