Cummingtonite
Cummingtonite is a monoclinic amphibole mineral with the chemical formula ☐Mg2Mg5Si8O22(OH)2. It is a member of the amphibole group, specifically classified as a tectosilicate in the Strunz system (9.DE.05) and in the Dana classification as 66.1.1.1. The mineral exhibits a prismatic crystal habit and typically displays a dark green to black color. It has a vitreous to dull luster, a hardness of approximately 5.5 to 6 on the Mohs scale, and a density of around 3.0 to 3.4 g/cm³. Cummingtonite is commonly found in metamorphic and igneous rocks and is characterized by its fibrous or granular appearance.
