Mica minerals can be formed in various geological conditions. The biotite is one of the main minerals in igneous rocks made, are distributed in most plutonic hypabyssal rocks. And a rockformingmineral Muscovite is widely distributed, with output in igneous, sedimentary and metamorphic rocks in phlogopite are mainly. Produced in the ultrabasic rocks and dolomitic marble. Many valuable industrial mica mainly occurs in pegmatite and metamorphic rocks in metamorphic rocks. Large phlogopite is a product which is rich in volatile components of magmatite of rock metasomatism. Fine grained muscovite, paragonite and sericite, and hydrothermal alteration related almost. Lithium mica found only in granite pegmatite and granite related with high temperature gas into hydrothermal deposits. The mica metamorphic type and composition of the protolith and metamorphic degree, magnesium rich carbonate metamorphic easy gold mica; Al rich rocks Metamorphism is easy to form muscovite and biotite
Synthetic mica, also called fluoro mica, is prepared by chemical melting and cooling crystallization at high temperature. Its crystal fraction is KMg3 (AlSi3O10) F2, which belongs to monoclinic system, and is a typical layered silicate
Muscovite schist occurs mainly in acidic magmatite; in addition, also often appeared in the greisen rock and metamorphic schist and gneiss. Produced in granite muscovite, often formed with great industrial value of crystal formation; pegmatite Muscovite is multi-stage; hydrothermal metal ore bed and hydrothermal metamorphic rocks China is generally, sericite, formation of Sericite muscovite; in metamorphic rocks are widely distributed, it is involved in the formation of clayey rocks under high temperature and potassium.
Mica (MICA) is one of the most widely distributed rock forming minerals, including potassium, aluminum, magnesium, iron, lithium and other layered structures;
