Tectosilicates are composed of interconnected SiO₄ tetrahedrons where all the oxygens are shared with other tetrahedrons yielding a silicon to oxygen ratio of 1:2. Where only silicon and oxygen are present gives rise to the Quartz family composed of SiO₂ . In most other Tectosilicate minerals, the aluminum ion can substitutes for the silicon ion in the tetrahedrons are called with Al-Si framework.
