Quartz and SiO2—Simple Yet Exciting
Yuanming Pan, Jens Götze, Axel Müller, Gerald RaabDespite their simple chemical composition, silica (silicon dioxide, SiO2) minerals comprise a complex system with diverse polymorphs of distinct crystal structures and different stabilities and properties. Quartz is arguably the most important mineral throughout human history, from early survival tools to critical materials for modern advanced technology. In addition, quartz and other silica polymorphs and varieties are excellent archivers and important tools for deciphering geological, environmental, and planetary processes and histories.
