*muscovite* An important rockforming mineral [1] and member of the mica group with composition K2Al4[Si3AlO10]2(OH,F)4 (see MICAS [2]); when K is replaced by Na the mineral is called paragonite and is related to the phyllosilicates [3] (sheet silicates) lepidolite [4] and zinnwaldite [5] (both
Muscovite is the only common mineral that can be perfectly cleaved into even, transparent sheets, making it quite easy to identify. It is one of the most common rockforming minerals and can be found in sedimentary, igneous and metamorphic rocks.
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)(FOH) 2, or 2 (Al 2 O 3) 3 (SiO 2) 6 (H 2 O). It has a highly perfect basal cleavage yielding remarkably .
Muscovite is the most common of the Mica Group minerals. It can be found in igneous, metamorphic and sedimentary rocks such as pegmatites, gneisses, schists and most common in granitic rocks where it is found in large crystals. These crystals are referred to as "books" since they can be split into paperthin sheets. It is easily identified due to its smooth cleavage which allows it to be split ...

Magnesium (Mg) is the eighth most abundant element and constitutes about 2% of the Earth's crust, and it is the third most plentiful element dissolved in seawater. Although magnesium is found in over 60 minerals, only dolomite, magnesite, brucite, carnallite, and olivine are of commercial importance. Magnesium and other magnesium compounds are also produced from seawater,

Illite is a group of closely related nonexpanding clay minerals. Illite is a secondary mineral precipitate, and an example of a phyllosilicate, or layered aluminosilicate. Its structure is a 2:1 sandwich of silica tetrahedron (T) – alumina octahedron (O) – silica tetrahedron (T) layers. The space between this TOT sequence of layers is occupied by poorly hydrated potassium cations which ...

MICA, a generic term, refers to any of a group of approximately 30 silicate minerals occurring as nonfibrous plates. Muscovite (hydrated aluminium potassium silicate[KAl2(AlSi3O10)(F, OH)2 ])and phlogopite (potassium magnesium aluminum silicate hydroxide) are the two major micas of commerce.

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible. Layering in the divalent, or brittle, micas
