A silicate is a mineral made up of of silicon and oxygen. These two elements form a significant amount of the Earth's crust and likewise silicates are a significant portion.
Silicates are often of the form SiO4 which forms a tetrahedron. These units can then be linked together to form regular lattices - either chains, sheets, or larger frameworks.
