Cummingtonite
Cummingtonite is a metamorphic amphibole with the chemical composition (Mg,Fe)7Si8O22(OH)2, magnesium iron silicate hydroxide. Monoclinic cummingtonite is compositionally similar and polymorphic with orthorhombic anthophyllite, which is a much more common form of magnesium-rich amphibole, the latter being metastable. -
