Amphibole
Definition
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.
