A subclass of the Silicates. 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 ...

Zeolites are aluminosilicate minerals that occur as low-temperature (generally less than 200°C) alteration products of volcanic and feldspathic rocks. They are well known in cavities of basalt, having crystallized as a result of diagenetic or hydrothermal alteration (Figure 1 ). Some zeolites completely replace rhyolitic tuff in saline ...

The vast majority of the minerals that make up the rocks of Earth's crust are silicate minerals. These include minerals such as quartz, feldspar, mica, amphibole, pyroxene, olivine, and a great variety of clay minerals. The building block of all of these minerals is the silica tetrahedron, a combination of four oxygen atoms and one silicon atom.

For example, Be and Zn ions are bound tetrahedrally to oxygen of silicate in these two minerals: phenacite, B and willemite, Zn 2 SiO 4. In olivine, (Fe, Mg) 2 SiO 4, the cations are either of Fe 2+ or Mg 2+. This formula suggests that this mineral is a mixed form of salt of iron and magnesium silicates.

Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
