Serpentinization is the process of hydroxylation olivine-rich ultramafic rocks to produce minerals such as serpentine, brucite and magnetite. This commonly accompanied by Fe oxidation release H2, which can be involved in abiotic reaction pathways leading genesis light hydrocarbons methane (CH4). Examples this phenomenon exist at seafloor, serpentinite-hosted Lost City hydrothermal field, on lan...

Serpentinization of mantle peridotites has first order effects on the rheology and tectonic behavior oceanic lithosphere, global water cycle, biosphere at mid-oceanic ridges. Investigating serpentinization abyssal is limited by scarce occurrences or close to ocean floor slow ultra-slow ridge environments where peridotite exposed long-lived detachments. The processes controlling hydration upper ...
