Quartz is a mineral with a hard, crystalline structure composed of silica (silicon dioxide). Its atoms form a continuous framework of SiO4 silicon-oxygen tetrahedra, with each oxygen atom shared between two tetrahedra. This results in a chemical formula of SiO2. Quartz is classified as a framework silicate mineral structurally, and as an oxide mineral compositionally. It is the second most abundant mineral in the Earth's continental crust, following feldspar.
