To address the question of the initiation and mechanisms involved in the process of
subduction zone formation, we explored most of the available evidence for the subduction …

Compositions of∼ 2500 spinel–olivine pairs and 400 melt inclusion–spinel pairs have been
analysed from 36 igneous suites from oceanic, arc and intraplate tectonic settings. Our data …

Boninites are rare, high-Si, high-Mg, low-Ti lavas that have considerable tectonic
significance, especially for recognizing and interpreting episodes of subduction initiation in …

Miyashiro (1973) famously initiated a debate on the tectonic setting of ophiolite complexes
by proposing that 'the Troodos ophiolitic complex was probably formed in an island arc'. This …

Variations of oxygen isotope ratios in arc-related lavas can constrain the contributions of
subducted crustal igneous rocks, sediments, and fluids to the sub-arc mantle. We have …

'Pyrolite'was chosen by Ringwood (1962a, b) as the name for a model chemical composition
for the mantle, consisting predominantly of pyroxene and olivine. Subsequently, the pyrolite …

Flood basalts are one of the remaining enigmas in global mantle petrology. They come in
enormous quantities of up to 106 km3 of mantle-derived melt, and they erupt in rather short …

The subarc mantle is a primary control on the composition of arc magmas and the formation
of arc-related ore deposits. Elevated ferric iron contents in arc lavas have been interpreted …

A tholeiite–boninite terrane occurs as a~ 4.5-km-thick massif with lavas and intrusions in the
Dachadaban (DCDB) area, the middle part of the North Qilian oceanic-type suture zone. It …

The accessory mineral chrome–spinel,[(Mg, Fe)(Cr, Al, Fe) 2O4], is well-established as a
useful, alteration-resistant petrogenetic and tectonic setting indicator for mafic–ultramafic …
