    Abstract. It is argued that the high-Mg content (mg-number = 95 ± 3) of the serpentine minerals in serpentinized peridotite is a consequence of the environmental Fe 2+ Mg −1 exchange potential imposed on the system by the abundance of olivine and orthopyroxene. Mass balance in the serpentinization reaction then requires the precipitation of an iron-rich mineral that in most cases is magnetite.
