Quartz is a naturally occurring mineral crystal formed from silicon dioxide (SiO₂). It is one of the most widely distributed minerals in the Earth’s crust and is known for its exceptional resistance to environmental and chemical degradation. Quartz is found in all major rock categories—igneous, sedimentary, and metamorphic. It is recognized for its mechanical...
