The family includes orthosilicate SiO4 4 ( x = 0 ), metasilicate SiO2 3 ( x = 1 ), and pyrosilicate Si2O6 7 ( x = 0.5, n = 2 ). These are rock-forming minerals. The subscripts H and S denote the values along the Hugoniot and isentrope, respectively. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals. chemistry. The conditions and the environment during which the cooling occurs will determine the type of silicate formed. The general formula of three-dimensional or tectosilicate or framework silicate is (SiO)n. All the oxygen atoms of Si04 are united with other tetrahedra and hence forming the three dimensional network. In most minerals in the Earth's crust, each silicon atom is the center of an ideal silicon-oxygen tetrahedron. Its general formula is ( S i O. Chains of edge sharing octahedra cross-linked by single and bow tie silicate units. The general formula is (Ca,Na,H)(Al,Mg,Fe,Zn) 2 (Si, Al) 4 O 10 (OH) 2-xH 2 O, where x represents a .
