    geologyscience.com/minerals/glaucophane When iron replaces the magnesium in its structure, it is known as ferroglaucophane. Glaucophane occurs in schists formed by high-pressure metamorphism of sodium-rich sediments at low temperatures (up to 400°F/200°C) or by the introduction of sodium into the process. Glaucophane is often accompanied by jadeite, epidote, almandine, and chlorite

  • Glaucophane - Wikipedia

    en.wikipedia.org/wiki/Glaucophane Glaucophane forms a solid solution series with ferroglaucophane; Na 2 (Fe,Mg) 3 Al 2 Si 8 O 22 (OH) 2. Glaucophane is the magnesium-rich endmember and ferroglaucophane is the iron-rich endmember. Ferroglaucophane is similar to glaucophane but is slightly denser and hence increased specific gravity.
