  • Muscovite Wikipedia

    Muscovite (also known as common mica, isinglass, or potash mica) is a hydrated phyllosilicate mineral of aluminium and potassium with formula K Al 2 (AlSi 3 O 10)(F,OH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O).It has a highly perfect basal cleavage yielding remarkably thin laminae (sheets) which are often highly elastic.Sheets of muscovite 5 meters × 3 meters (16.5 feet × 10 feet) have been

  • Muscovite an overview ScienceDirect Topics

    Muscovite mica is a natural resource excavated from a mica mine. Large slabs of muscovite mica are found in pegmatite. It can be easily cleaved into thin flat pieces by a sharp needle or knife. The atomic composition of muscovite mica is KAl 3 Si 3 O 10 (OH) 2 and density is 2.76–3.10 g/cm 3 (the commonly quoted density is 2.8 g/cm 3).

    Muscovite and sometimes similar species were earlier called mica (Phillips and Kersey, 1706), glimmer (Phillips and Kersey, 1706), and isinglass (1747 according to OED) but all of these terms are still in use to some degree. It should be noted that mica, glimmer, and isinglass were also used for a variety of materials before these given dates

  • Muscovite Mineral Uses and Properties

    Muscovite is the most common mineral of the mica family. It is an important rock-forming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it readily cleaves into thin transparent sheets. Muscovite sheets have a pearly to vitreous luster on their surface.

  • Muscovite

    Muscovite in igneous rocks is usually associated with quartz, potassium feldspars, biotite and amphibole minerals. In pegmatites, beryl and tourmaline may be added to that list. Within metamorphic rocks, muscovite is typically found with other members of the mica group, such as biotite and chlorite.
