Quartz is a mineral composed of silicon and oxygen, with a chemical composition of SiO 2. It is the most abundant mineral in Earth's crust and is resistant to both chemical and physical weathering. When rocks weather away, the residual material usually contains quartz. This is why the sand at most of the world's beaches is quartz.
This structure is the building block of many important minerals in the crust and mantle. Silicon has a charge of +4, and oxygen has a charge of -2, so the total …
