The oxygen fugacity (f O2) of convecting upper mantle recorded by ridge peridotites varies
by more than four orders of magnitude,–. Although much attention has been given to …

To gain insights into the composition and heterogeneity of Earth's interior, the partial
pressure of oxygen (oxygen fugacity, or f O2) in igneous rocks is characterized. A surprising …

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

Pyroxenite veins are commonly observed in the mantle section of ophiolites, reflecting a
variety of melts that percolate through the mantle, react, and finally crystallize in the …

The study of the oxidation state of lithospheric mantle-derived rocks allows modelling the
deep cycle of volatiles (eg, C, H, O, N and S) in the Earth's interior, which in turn plays a role …

Abstract The Marion Rise, located in the central portion of the Southwest Indian Ridge
(SWIR), marks a relief high but is overall covered with a thin crust, and thus is inferred to be …

Ophiolitic mantle peridotites show large variations in their geochemical compositions, which
provide important information for the histories of mantle melting, melt metasomatism and …

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 …

The geochemical evolution of mantle peridotite during subduction initiation (SI) remains an
issue in geosciences. This study presents geochemical and Ca isotopic data for Tiébaghi …

The phenomena of reactive percolation of enriched asthenospheric melts and pervasive
melt-rock interactions at mid oceanic ridge-rift systems are the principal proponents for …
