I want to know the answer to the following question:
Where do you find silicate?
All the background I'm provided with is that "In the absence of atmospheric oxygen (O_2), in deep geological conditions prevailing far away from Earth atmosphere, hydrogen (H_2) is produced during the process of serpentinization by the anaerobic oxidation by the water protons (H+) of the ferrous (Fe2+) silicate present in the crystal lattice of the fayalite (Fe_2SiO_4, the olivine iron-endmember).". Is that enough to answer the question?
Answer: yes
