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

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 …
Magnetite breakdown during subduction of serpentinised ultramafic rocks may produce oxidised fluids that oxidise the deep Earth and/or the sub-arc mantle, either via direct …
