TLDR
The Melanesian Borderlands as discussed by the authors is a complex of seven subdivisions, most of which are Cainozoic tectonic unities, including the Bismarck Sea and surrounding, Solomon Block, Coral Sea and eastern extension, New Hebrides and South Fiji Basins, South Fiji Basin and Lau Basin, Fiji Platform, Lau and Tonga Ridges.About:

Cenozoic geological and plate tectonic evolution of SE Asia and the SW Pacific: computer-based reconstructions, model and animations
TL;DR: In this article, a model for the Cenozoic development of the region of SE Asia and the SW Pacific is presented and its implications are discussed, accompanied by computer animations in a variety of formats.
Journal ArticleDOI
Back-arc opening and the mode of subduction
Seiya Uyeda,Hiroo Kanamori +1 more
TL;DR: In this paper, the authors investigated the difference in the stress state in the back-arc area between the two types of trench-arc systems: compression in the Chilean type and tension in the Marianas type.
Journal ArticleDOI
On the evolution of marginal basins
Brian Taylor,Garry D. Karner +1 more
TL;DR: Back arc basins are those marginal basins located behind active or inactive trench systems and whose origin is inferred to be subduction-related as discussed by the authors, which are not generically back arc, but rather are related to the initiation of subduction, continental rifting, or plate boundary readjustments.

Pacific Plate biogeography, with special reference to shorefishes
TL;DR: It is the thesis of this study that the Pacific lithospheric plate (Pacific Plate) forms a major subunit of the Indo-Pacific biogeographic region and the sharp decrease in numbers of taxa as one proceeds eastward across the western margin of the Pacific Plate is defended on two primary grounds.

Age and Geochemistry of Basement and Alkalic Rocks of Malaita and Santa Isabel, Solomon Islands, Southern Margin of Ontong Java Plateau
TL;DR: In this article, the Malaita Older Series and Sigana Basalts were used to confirm the existence of Ontong Java Plateau (OJP) crust on these islands, indicating a uniform hotspot4ike mantle source with a slight 'Dupal' signature for the worlds largest oceanic plateau.

Subduction and Accretion in Trenches
TL;DR: In this article, the authors investigated the mechanisms by which material is subducted or accreted to the upper plate and found that the sediment cover on the downgoing plate and some of the igneous crust appears to be stripped off the plate before it reaches a point beneath the volcanic chain.
Journal ArticleDOI
Ridges and Basins of the Tonga‐Kermadec Island Arc System
TL;DR: In this article, a thin cover of rapidly deposited sediment suggests that the morphology of the interarc basin, which consists of linear ridges and troughs with approximate relief of 1000 meters, is no older than latest Tertiary.
Journal ArticleDOI
Mineralogy and Geochemistry of the Younger Volcanic Islands of Tonga, S.W. Pacific
A. Ewart,W. B. Bryan,J. B. Gill +2 more
TL;DR: The basaltic andesites are interpreted to be the product of direct peridotitic fusion within the mantle, presumably in the region overlying the seismic zone, and modified by olivine fractionation during ascent.
Journal ArticleDOI
Evolution of Arc Systems in the Western Pacific
TL;DR: A review of recent data and the resulting ideas which bear on evolution of arc systems in the western Pacific can be found in this paper, where the authors assume the validity of plate tectonics and concentrate on processes by which subduction is manifested in the geologic record.
Journal ArticleDOI
Focal mechanisms and plate tectonics of the southwest Pacific
Tracy Johnson,Peter Molnar +1 more
TL;DR: In this article, the authors determined new focal mechanisms for earthquakes on the belt of seismic activity separating the Pacific and Australian plates, and showed that the pole of rotation for the Australian and Pacific plates is nearby and to the east of this feature.
