Silicates
9th class - Silicates This group of minerals is extremely large. The fundamental building block of silicates is the SiO4 tetrahedron, and silicate structures are classified according to the degree of polymerization by corner-sharing of the tetrahedra:
Nesosilicates - have insular SiO4 tetrahedra. Sorosilicates - have cluster structures with two, or rarely more, corner- sharing tetrahedra. Cyclosilicates - have tetrahedra connected into rings. Inosilicates - have tetrahedra in chains of infinite length. Phyllosilicates - have rings of tetrahedra linked into continuous sheets. Tektosilicates - have tetrahedra linked into a 3-dimensional framework.
