Cummingtonite

Fibrous, brownish crystals of cummingtonite - Locality: Dannemora Mine, Uppsala Län, Uppland, Sweden

Cummingtonite is a metamorphic amphibole with the chemical composition (Mg,Fe)2(Mg,Fe)5Si8O22(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.
