• 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 ...

  • Richterite - an overview | ScienceDirect Topics

    www.sciencedirect.com/topics/earth-and-planetary-sciences/richterite Blue-green richterite amphibole forms generally less than 15 vol% of the glimmerites and averages 5 vol% overall. However, Puustinen (1971, 1972) described carbonate-amphibole rocks that contain up to 50 vol% or more amphibole with richterite crystals up to several centimeters in length. In our experience, these rock types must be extremely rare.
