#inosilicate

• Aluminosilicate — A complex mineral within the silicate class (representing a large portion of the Earth's crust, such as feldspars, zeolites, and micas) in whose crystalline frameworks part of the silicon atoms are replaced by aluminum atoms bound to oxygen.
• Alumosilicate — A terminological or spelling variant (influenced by German and Russian nomenclatures) for 'aluminosilicat' (aluminosilicate); a complex mineral within the silicate class in whose crystalline frameworks part of the silicon atoms are replaced by aluminum atoms.
• Amphibole — A generic name for an extensive group of inosilicate minerals with a monoclinic or orthorhombic crystalline structure, composed of double chains of silicon dioxide tetrahedra. This structural group, which includes hornblende, actinolite, and tremolite, typically contains iron, magnesium, calcium, and sodium ions, being an essential constituent of many dark-colored igneous and metamorphic rocks.
