Tracking the final fate of subducting carbon is crucial to understanding global carbon cycles
and climate changes in the history of the Earth. Available geochemical tracers such as …

Subduction at convergent margins introduces a range of sedimentary and crustal materials
into the mantle, providing the most dominant form of heterogeneity in the source of oceanic …

The nine editions of Stable Isotope Geochemistry have appeared over a time span of nearly
50 years. The first edition (1973) appeared as a slim book of 135 pages. Due to the rapid …

Sulfur belongs among H2O, CO2, and Cl as one of the key volatiles in Earth's chemical
cycles. High oxygen fugacity, sulfur concentration, and δ34S values in volcanic arc rocks …

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) …

Subduction zones facilitate chemical exchanges between Earth's deep interior and
volcanism that affects habitability of the surface environment. Lavas erupted at subduction …

Elevated H2O concentrations and oxygen fugacities are two fundamental properties that
distinguish magmas formed in subduction zones from new crust generated at mid-ocean …

Fluids liberated from subducting slabs are critical in global geochemical cycles. We
investigate the behaviour of Mo during slab dehydration using two suites of exhumed …

Previous studies have concluded that dehydration of serpentinites in subduction zones
produces oxidizing fluids that are the cause of oxidized arc magmas. Here, observations of …

Whether arc mantle is more oxidized than oceanic mantle is persistently debated. The
behavior of multivalent vanadium (V) is oxygen fugacity (fO2) sensitive, and the ratios of V to …
