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 Silica Minerals Education Coalition,Also called silica sand or quartz sand, silica is silicon dioxide (SiO 2 ). Silicon compounds are the most significant component of the Earth’s crust. Since sand is plentiful, easy to mine and relatively easy to process, it is the primary ore source of silicon. The metamorphic rock, quartzite, is another source.
