Silicate Minerals - an overview ScienceDirect Topics

Mineralogists classify silicate minerals based on the silicate polyanions that define their essential crystal structure (Table 3.3). Cation substitution of tetrahedral Si 4+ by Al 3+ , which leaves the essential aluminosilicate tetrahedral polyanion network intact, is rare or nonexistent in neso-, soro-, cylco-, and single-chain insosilicates.

Silicate Mineral - an overview ScienceDirect Topics

4.4 Identification of Silicate Minerals. By their nature, silicate minerals contain Si in a huge range of environments and variety of structural units. Compounds containing structural units corresponding to those found in various minerals are frequently encountered in inorganic materials, either in their own right or as products or intermediates of inorganic syntheses.
