forming minerals The SiO4 Tetrahedrons Silicates are the most important rock forming minerals. They are composed of a very stable molecule made up of Silicon and Oxygen atoms. Those form through covalent bonds a SiO4 tetrahedron. These tetrahedra can be combined in multiple ways. For example, they can be arranged by

7) THREE DIMENSIONAL SILICATES (TECTO SILICATES) The general formula of three dimensional or tecto silicates is (SiO 2) n. All the oxygen atoms of SiO 4 are shared with other tetrahedra and thus by forming three-dimensional network. E.g. SiO 2 - Quartz, Tridymite and Crystobalite - These are the crystalline forms of silica.

Silicate minerals - Wikipedia

Silicate minerals are rock-forming minerals made up of silicate groups. They are the largest and most important class of minerals and make up approximately 90 percent of the Earth's crust. In mineralogy, silica (silicon dioxide) SiO 2 is usually considered a silicate mineral. Silica is found in nature as the mineral quartz, and its polymorphs.

Tectosilicates & Other Minerals

The tectosilicates or framework silicates have a structure wherein all of the 4 oxygens of SiO 4-4 tetrahedra are shared with other tetrahedra. The ratios of Si to O is thus 1:2. Since the Si - O bonds are strong covalent bonds and since the structure is interlocking, the tectosilicate minerals tend to have a .
