But it's often indistinguishable from some stones of this group, such as Cummingtonite. It's a stone that's usually white, green, greenish grey, brownish green, or clove brown in color. The mining of Anthophyllite started in Finland in 1890.
Cummingtonite – Cummingtonite is a metamorphic amphibole with the chemical composition 25Si8O222, magnesium iron silicate hydroxide. Monoclinic cummingtonite is compositionally similar and polymorphic with orthorhombic anthophyllite, which is a more common form of magnesiumrich amphibole.
Cummingtonite is a metamorphic amphibole with the chemical composition (Mg,Fe 2+) 2 (Mg,Fe 2+) 5 Si 8 O 22 (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 .
Anthophyllite is an amphibole mineral: (Mg, Fe)7Si8O22(OH)2, magnesium iron inosilicate hydroxide. Anthophyllite is polymorphic with cummingtonite. Some forms of anthophyllite are lamellar or fibrous and are classed as asbestos. The name is derived from the Latin word anthophyllum, meaning clove, an allusion to the most common color of the mineral.
Cummingtonite. The chemical formula of mineral Cummingtonite is indicated by (Mg, Fe)7Si8O22(OH)2 or Magnesium Iron Silicate Hydroxide. Cummingtonite is actually a Silicate mineral. The name Cummingtonite was derived from the name of its type of locality in .
The amphibole cummingtonite (Mg, Fe)7Sig022(OH)2 is structurally and compositionally very similar to orthopyroxene [7, 8]. Mgt+, Fe2+ ions occur in octahedral strips (alternately three and four octahedra wide) held together by ribbons of Si40ll double chains. There are .

The crystal in the photograph was collected from a road cut north of Indian Bay, NF. It is the property of W. Lawson Dickson, a geologist with the Geological Survey. Cummingtonite. Cummingtonite is an ironmagnesium silicate that usually occurs in aggregates of fibrous crystals, often radiating.
Other magnesiumrich legumes include chickpeas, white beans, and lentils. From stews to salads, you can add beans to nearly any dish. You'll get an extra dose of fiber, protein, iron, and zinc.
Cummingtonite is a metamorphic amphibole with the chemical composition (Mg,Fe2+)2(Mg,Fe2+)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 magnesiumrich amphibole, the latter being metastable.
