Can High Temperatures Enable Silica Formation in Anaerobic Lunar Environments?

[cph]

Perhaps the recent silica found on the Moon highlands resulted from the extreme conditions of temperature and pressure of planetesimal collision with proto-earth. Can covalent bonds be broken at high temperatures, allowing oxygen incorporation in an anaerobic environment? What is the highest experimental temperature for silica formation in an anaerobic environment?

No idea what you are asking about. Can the bonds be broken - sure, it is all matter of how high the temperature is. But I have no idea how do you expect it to be related to silica creation. If there is a mixture containing silicon and oxygen, SiO₂ is usually one of the most thermodynamically stable substances between likely products.
