  • Muscovite mica The mineral Muscovite information and pictures

    The Mineral muscovite. Muscovite is the most common form of mica. Its name is derived from quot;Muscovy Glassquot;, which describes thick sheets of transparent mica that were once used as a glass substitute in Russia. Because of Muscovite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.
