-are compounds in which metallic elements combine with either single or linked Si-O terahedra (SiO4). Structurally, silicates are divided into six classes: Nesilicates, Sorosilicates, Cyclosilicates, Inosilicates, Phylosilicates and Tectosilicates.
Silicates are the largest and most abundant class of minerals, while primary silicates are the main constituents of igneous and metamorphic rocks.
