Context: <response>: ```If oxygen no dey inside air (O2), for deep geological conditions wey dey far from Earth atmosphere, hydrogen (H2) dey produce during the process of serpentinization by the anaerobic oxidation by the water protons (H+) of the ferrous (Fe2+) silicate wey dey inside the crystal lattice of the fayalite (Fe2SiO4, the olivine iron-endmember). The reaction wey dey lead to the formation of magnetite (Fe3O4), quartz (SiO2) and hydrogen (H2) na like this:```
