By means of electron probe,wet chemical analysis and X-ray powder diffraction analysis the amphibole of the Huichang shoshonite is evidenced to belong to calcic amphibole and is determined as magnesiohastinsite.

The formation of alkaline metasomatites with charoite, potash richterite (richterite asbestos) and blue nephrite is conditioned by inert behaviour, first of all, of silicic acid and alkalis (with a varying role of Na 2O and K 2O) and by quite mobile FeO, MgO, CaO, and Al 2O 3.

The chemical compositions of the final crystals, whichare composed of diopside and richterite, of this type glass-ceramics are almost the same as thoseof the parent glass.

The Upper Archean Enclavement of Magnesioriebeckites-Bearing Gneiss in Liaoning Province: Old Glaucophane-Schist Relict;

On the basis of the petrology,mineral chemistry and p-t conditions of the amphibole-bearing schists across Guandian,Zhangbaling,amphiboles in this schist belong to magnesioriebeckite,the average oxide contents: Al2O3=3.
