Actinolite has a monoclinic crystal structure, characterized by elongated prismatic crystals that typically exhibit a fibrous or bladed habit. It belongs to the amphibole group of minerals and is composed primarily of calcium, magnesium, and iron silicate. The crystal lattice features chains of double tetrahedra, which are linked by other metal cations, contributing to its unique physical properties. Actinolite is commonly found in metamorphic rocks, often associated with other amphiboles and metamorphic minerals.
