Carbon fluxes in subduction zones can be better constrained by including new estimates of
carbon concentration in subducting mantle peridotites, consideration of carbonate solubility …

We summarize the uptake of carbon and sulfur during serpentinization of seafloor
peridotites, and discuss the fate of these volatiles during subduction of serpentinite. We use …

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 …

We present 28 multiple sulfur isotope measurements of seawater sulfate (δ 34 S SO 4 and Δ
33 S SO 4) from the modern ocean over a range of water depths and sites along the eastern …

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 …

The subduction of oceanic slabs with diverse lithologies greatly contributes to the
geochemical heterogeneity of the mantle. Oceanic metasomatism leads to the formation of …

Abstract The Oman Drilling Project “Multi‐Borehole Observatory”(MBO) samples an area of
active weathering of tectonically exposed peridotite. This article reviews the geology of the …

Subduction is a key component of Earth's long‐term sulfur cycle; however, the mechanisms
that drive sulfur from subducting slabs remain elusive. Isotopes are a sensitive indicator of …

The potential for molecular hydrogen () generated via serpentinization to fuel subsurface
microbial ecosystems independent from photosynthesis has prompted biogeochemical …

Abstract Evaluation of volcanic and hydrothermal fluxes to the surface environments is
important to elucidate the geochemical cycle of sulphur and the evolution of ocean …
