Forms: 1700s actinolyte, 1700s–1800s actynolite, 1700s– actinolite.

Origin: Formed within English, by compounding. Etymons: actino- comb. form, -lite comb. form¹.

Etymology: < actino- comb. form + -lite comb. form¹, in allusion to its elongated and often radiating crystal structure.

Mineralogy.

An iron-containing silicate mineral of the amphibole group, typically green or greenish grey with an elongated crystal structure, occurring widely esp. in metamorphic rocks.Actinolite is a basic silicate of calcium, iron, and magnesium, Ca₂(Mg, Fe)₅Si₈O₂₂(OH)₂. Crystal system: monoclinic. Varieties include forms of asbestos and jade (nephrite).
