• Sodic-ferrogedrite: Mineral information, data and localities.

    www.mindat.org/min-7304.html Named as the sodium-bearing and ferrous iron-dominant orthoamphibole resembling gedrite. In order to better distinguish between amphibole end-member member compositions, the CNMNC has decided to rename sodic-ferrogedrite.
  • Ferrogedrite - Wikipedia

    en.wikipedia.org/wiki/Ferrogedrite Ferrogedrite is an amphibole mineral with the complex chemical formula of ☐Fe 2+ 2 (Fe 2+ 3 Al 2)(Si 6 Al 2)O 22 (OH) 2.It is sodium and calcium poor, making it part of the magnesium-iron-manganese-lithium amphibole subgroup. Defined as less than 1.00 apfu (atoms per formula unit) of Na + Ca and consisting of greater than 1.00 apfu of (Mg, Fe 2+, Mn 2+, Li) separating it from the calcic ...

    www.galleries.com/minerals/silicate/inosilic.htm The Inosilicates include two distinct groups: the single chain and double chain silicates. In the single chain. group the tetrahedrons share two oxygens with two other tetrahedrons and form a seemingly endless chain.. The ratio of silicon to oxygen is thus 1:3. The tetrahedrons alternate to the left and then to the right along the line formed by the linked oxygens although more complex chains ...
