Experiment and observation have established the centrality of oxygen fugacity (f O 2) to
determining the course of igneous differentiation, and so the development and application of …

Subduction zone magmas are more oxidised on eruption than those at mid-ocean ridges.
This is attributed either to oxidising components, derived from subducted lithosphere (slab) …

The concentration of carbon in primary mid‐ocean ridge basalts (MORBs), and the
associated fluxes of CO2 outgassed at ocean ridges, is examined through new data …

From oxic atmosphere to metallic core, the Earth's components are broadly stratified with
respect to oxygen fugacity. A simple picture of reducing oxygen fugacity with depth may be …

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 …

Subduction may influence the oxygen fugacity (f (fugacity (O f 2) of the mantle and mantle-
derived magmas through the introduction of hydrated and oxidised altered oceanic crust …

Aerobic lifeforms, including humans, thrive because of abundant atmospheric O2, but for
much of Earth history O2 levels were low. Even after evidence for oxygenic photosynthesis …

Determining the evolutionary history of mantle oxygen fugacity (f o2) is crucial, as it controls
the f o2 of mantle-derived melts and regulates atmospheric composition through volcanic …

Basalts and peridotites from mid-ocean ridges record f O2 near the quartz-fayalite-magnetite
buffer (QFM), but peridotite partial melting experiments have mostly been performed in …

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 …
