description Actinolite Overview
Actinolite is a calcium magnesium iron amphibole mineral that forms a compositional series with tremolite. It commonly occurs in metamorphic rocks, especially rocks formed when magnesium- and calcium-rich materials are altered during metamorphism. Actinolite may appear green, gray-green, or nearly black and can form elongated or fibrous crystals. Fine-grained actinolite-tremolite aggregates are components of some nephrite jade, although actinolite itself is not synonymous with all nephrite.
