In mineralogy, silicate minerals are classified into seven major groups according to the structure of their silicate anion: Note that tectosilicates can only have additional cations if some of the silicon is replaced by an atom of lower valence such as aluminium.
U mineralogiji, silikatni minerali se klasifikuju u 7 glavnih grupa prema strukturi njihovog silikatnog anjona: Tektosilikati mogu jedino da imaju dodatne katjone ako su neki od atoma silicijuma zamenjeni atomom niže valence, kao što je aluminijum.
