  • Riebeckite - Wikipedia

    en.wikipedia.org/wiki/Magnesio-riebeckite Riebeckite is a sodium-rich member of the amphibole group of silicate minerals, chemical formula Na 2 (Fe 2+ 3 Fe 3+ 2)Si 8 O 22 (OH) 2.It forms a solid solution series with magnesioriebeckite. It crystallizes in the monoclinic system, usually as long prismatic crystals showing a diamond-shaped cross section, but also in fibrous, bladed, acicular, columnar, and radiating forms.

  • RIEBECKITE (Sodium Iron Magnesium Silicate Hydroxide)

    www.galleries.com/Riebeckite Riebeckite is the ferrous iron rich member of the series and as the name implies, magnesioriebeckite is the magnesium rich member. Magnesioriebeckite formula, Na 2 (Mg, Fe) 3 Fe 2 Si 8 O 22 (OH) 2 , is nearly identical to riebeckite and so are the properties of the two minerals.

    www.britannica.com/science/riebeckite Riebeckite, a sodium-iron silicate mineral [Na2Fe2+3Fe3+2Si8O22(OH)2] in the amphibole family. It forms part of a solid-solution series that includes both magnesioriebeckite (formed when iron is replaced by magnesium) and glaucophane (formed when iron is replaced by magnesium and aluminum).

    www.minerals.net/mineral/riebeckite.aspx Riebeckite forms in two very different habits. The darker-colored forms which are individually crystallized are generally of igneous origin, such as volcanic rock and pegmatites. The finely fibrous variety, known as Crocidolite, usually originates from altered metamorphic rocks. The Crocidolite variety is a type of asbestos, and is sometimes also referred to as "blue asbestos".
