Abstract International Ocean Discovery Program Expedition 352 to the Izu‐Bonin forearc
cored over 800 m of basement comprising boninite and boninite‐series lavas. This is the …

Understanding whether ophiolites formed during subduction inception or above long-lived
subduction zones poses an outstanding challenge as modern examples of incipient …

To understand the oxygen fugacity (fO2) during subduction initiation, we examined proto‐arc
boninites and associated mantle peridotites from the Troodos ophiolite, Cyprus. The …

Oxygen fugacity (ƒO 2) varies systematically across tectonic environments. The typically
high ƒO 2 recorded in arc settings relative to oceanic ridges is attributed to recycling of …

Olivine-rich lavas in the Margi area, Cyprus, are part of the boninitic Upper Pillow Lava
series of the Troodos ophiolite. Re-Os isotope compositions of both whole rock and olivine …

Hydrostatic pressure exerted by the ocean water column fundamentally influences magmatic
and hydrothermal processes in submarine volcanic settings and is therefore an important …

Boninites in many supra-subduction zone ophiolites are thought to mark the early stage of
subduction. The Troodos ophiolite in Cyprus contains a variety of volcanic rocks including …

The Kızıldağ (Hatay) ophiolite in southern Turkey represents a complete, although fault-
dissected, remnant of oceanic lithosphere that formed within the South Tethyan ocean …

Boninites are rare high magnesium andesites that often contain trace chromites. These
chromites precipitate from primitive boninitic melts and are thought to be carried to the …

Boninite has been widely accepted to be the melting product of highly refractory mantle with
the addition of slab-derived fluids. Previous studies have found that boninite, like other …
