• Richterite - Wikipedia

    en.wikipedia.org/wiki/Richterite Richterite is a sodium calcium magnesium silicate mineral belonging to the amphibole group. If iron replaces the magnesium within the structure of the mineral, it is called ferrorichterite; if fluorine replaces the hydroxyl, it is called fluororichterite.Richterite crystals are long and prismatic, or prismatic to fibrous aggregate, or rock-bound crystals.. Colors of richterite range from brown ...
