Silicon and oxygen are the two most abundant elements in Earth’s crust, in which they largely occur in combination with other elements as silicate minerals. Free silica (SiO2) appears as a mineral in crystallizing magma only when the relative abundance of SiO2 exceeds that of all other cations available to form silicates. Silica minerals thus occur only in magmas containing more
