    www.sunnyray.org/Types-of-silicate-minerals.htm Types of Silicate Minerals — Tectosilicates. Silicates are probably the most important class of minerals on our planet. We can classify them in several ways, and one of the most important is related to the spatial formation of bonds between the silicon and oxygen atoms.
  • tectosilicate | Structure & Facts | Britannica

    www.britannica.com/science/tectosilicate Tectosilicate, any member of a group of compounds with structures that have silicate tetrahedrons (each a central silicon atom surrounded by four oxygen atoms at the corners of a tetrahedron) arranged in a three-dimensional lattice. Each of the oxygen atoms of a given tetrahedron is shared with another tetrahedron.
  • Silicate mineral - Wikipedia

    en.wikipedia.org/wiki/Silicate_minerals 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.. On Earth, a wide variety of silicate minerals ...
  • Mineral Gallery - The Tectosilicate Subclass

    www.galleries.com/minerals/silicate/tectosil.htm The Tectosilicate Subclass is often called the "Framework Silicates" because its structure is composed of interconnected tetrahedrons going outward in all directions, forming an intricate framework analogous to the framework of large building. In this subclass all of the oxygens are shared with other tetrahedrons giving a silicon to oxygen ratio of 1:2.

Zeolites are tectosilicates with three-dimensional aluminosilicate structure containing water molecules, alkali and alkaline earth metals in their structural framework (Gottardi and Galli, 1985).The ability of zeolites to exchange cations in aqueous solution is very well documented.

    www.britannica.com/science/silicate-mineral Silicate mineral, any of a group of silicon-oxygen compounds that are widely distributed throughout much of the solar system. The silicates make up about 95 percent of Earth’s crust and upper mantle, occurring as the major constituents of most igneous rocks.
