Example of most abundant  three-dimensional silicate is ____?

The Feldspars are most abundant Alumino Silicate minerals in the Earth surface. The silicon atoms and aluminium atoms occupy the centres of interlinked. Tetrahedra of ${\mathrm{SiO}}_4^{-4}\text{ and }{\mathrm{AiO}}_4^{-5}$ . These tetrahedrals connect at each corner to other tetrahedral forming an intricate three dimensional , negatively charged frame work. The sodium cations sit with in the voids in this structure.

Zeolites and ultramarines are alumina silicates.

Beryl is a beryllium alumna silicate.
