How does silica affect the color of igneous rocks? | Socratic

Dec 20, 2015· Rocks that are high in silica tend to be pale in colour. Pure silica has the chemical formula SiO_2 - silicon dioxide. Glass is silica that has an amorphous structure, which means the silicon and oxygen atoms aren't in a repeating lattice. Quartz is the form that pure silica takes in nature. It has a tectosilicate structure, which means the atoms form a lattice of tetrahedra bonded together.
