Back-arc basins are formed by extensional processes similar to those occurring at mid-
ocean ridges. However, whereas the magmas erupted along the major ocean ridges are …

This paper presents a critique of the models proposed to explain the formation of back arc
basins: those marginal basins located behind active or inactive trench systems and whose …

When Harry Hess first proposed the theory of seafloor spreading, he imagined that mantle
peridotite upwelling at midocean ridges reacted with water to form a serpentinite oceanic …

The elemental compositions of terrestrial igneous rocks are reviewed with special emphasis
on those elements that partition strongly into the liquids in mafic and ultramafic systems …

Some of the more important constraints on crustal growth mechanisms are reviewed in
relation to the trace element composition of orogenic igneous rocks, with specific reference …

This paper focuses on the processes of arc rifting in the context of the volcanic, structural,
and sedimentologic evolution of the Izu-Bonin-Mariana arc-trench system. Middle and late …

Subduction zones represent major sites of chemical fractionation within the Earth. Element
pairs which behave coherently during normal mantle melting may become strongly …

Side-scan sonar imaging of the Central Lau Basin (SW Pacific) has revealed a Central Lau
Spreading Centre (CLSC) propagating southwards at the expense of an Eastern Lau …

Basaltic and hawaiitic lavas from the S Atlantic Ocean islands of Ascension, Bouvet, St.
Helena, Gough and Tristan da Cunha have been analysed for major elements and a wide …

Abstract The East Scotia Ridge is an active back-arc spreading centre located to the west of
the South Sandwich island arc in the South Atlantic Ocean, consisting of nine main …
