Brucite formation and dissolution in oceanic serpentinite
Tectonic exhumation exposes peridotite to aqueous solutions and, because peridotite is unstable in the presence of H 2 O over a wide range of temperatures and pressures, it undergoes a series of dissolution-precipitation and redox reactions to form serpentinite. In addition to serpentine, serpentinites commonly contain other minerals in varying proportions, …
