A hidden carbon cycle exists inside Earth. Every year, megatons of carbon disappear into
subduction zones, affecting atmospheric carbon dioxide and oxygen over Earth's history …

Deep fluids are important for the evolution and properties of the lower continental and arc
crust in tectonically active settings. They comprise four components: H2O, nonpolar gases …

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 …

Oxidation of the sub-arc mantle driven by slab-derived fluids has been hypothesized to
contribute to the formation of gold deposits in magmatic arc environments that host the …

The key role of serpentinites in the global cycles of volatiles, halogens and fluid-mobile
elements in oceans and in subduction zones is now ascertained by many studies …

Fluids in the deep crust and upper mantle appear to have played roles in the long-term
evolution of the subcratonic lithospheric mantle and the stabilities of the continents, in the …

High-pressure dehydration of serpentinite during subduction generates fluids that flux and
melt the overlying mantle wedge, forming primary arc basalts. These basalts are …

The partitioning of major and trace elements between eclogite and aqueous fluids with
variable salinity was studied at 700–800° C and 4–6 GPa in piston cylinder and multi anvil …

Many habitable zone (HZ) exoplanets are expected to form with water mass fractions higher
than that of the Earth. For rocky exoplanets with 10–1000× Earth's H 2 O but without H 2, we …

The net flux of carbon between the Earth's interior and exterior, which is critical for redox
evolution and planetary habitability, relies heavily on the extent of carbon subduction. While …
