Over the last decades, numerous studies have emphasized the role of serpentinites in the
subduction zone geodynamics. Their presence and role in subduction environments are …

Abyssal peridotites are ultramafic rocks collected from mid-ocean ridges that are the
residues of adiabatic decompression melting. Their compositions provide information on the …

Three distinct groups of eclogites (low-Mg–Ti eclogites, high-Ti eclogites and Mg-rich
eclogites) and ultramafic rocks from the depth interval of 100–680 m of the Chinese …

Submarine hydrothermal sulfide ores occur at mid-ocean ridges, intra-oceanic arcs and in
back-arc basins associated with host rocks of highly variable composition. Pyrite is the …

We provide new insights into the geochemistry of serpentinites from mid-ocean ridges (Mid-
Atlantic Ridge and Hess Deep), passive margins (Iberia Abyssal Plain and Newfoundland) …

Elements that can occur in more than one valence state, such as Fe, C and S, play an
important role in Earth's systems at all levels, and can drive planetary evolution as they cycle …

The results of detailed textural, mineral chemical, and petrophysical studies shed new light
on the poorly constrained fluid‐rock reaction pathways during retrograde serpentinization at …

Aqueous dihydrogen (H2, aq) is produced in copious amounts when seawater interacts with
peridotite and H2O oxidizes ferrous iron in olivine to ferric iron in secondary magnetite and …

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 …

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