Mica is a naturally occurring mineral dust often used in makeup foundations, as filler in cement and asphalt, and as insulation material in electric cables.
Mica. Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers.
What is Muscovite? Muscovite is the most common mineral of the mica family. It is an important rock-forming mineral present in igneous, metamorphic, and sedimentary rocks.
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.
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).
Muscovite is the most common form of mica. Its name is derived from "Muscovy Glass", which describes thick sheets of transparent mica that were once used as a glass substitute in Russia.

Properties and uses. The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and …
Geology rocks and minerals. The resulting foliation is coarser and more distinct than that of slate due to the higher degree of crystallisation of mica minerals biotite chlorite muscovite
Muscovite (mica schist), for instance, is pearlized, reflective and somewhat transparent. Schists are often used in jewelry and other types of artwork. Most schists are rarely used in buildings as the mica can split easily and they are not very strong. However, some types of schists are used in construction. There are buildings at Princeton University and the University of Pennsylvania that ...

Mica is a group of silicate minerals that are physically and chemically similar to one another. There are 37 known mica minerals, including biotite, lepidolite, muscovite and phlogopite.
mica Group of common rock-forming minerals characterized by a platy or flaky appearance. All contain aluminium, potassium and water; other metals, such as iron and magnesium, may be present. Micas have perfect basal cleavage. Common micas are muscovite and the biotite group. Muscovite is commonly found in coarse-grained acidic rocks, schists and gneisses, and in sedimentary rocks. The …
Muscovite Mineral Facts: Chemical Formula: KAl 2 (AlSi 3 O 10)(F,OH) 2 While predominantly a potash mica, nearly all muscovite contains some soda, due to …
Mica - Metaphysical Healing Properties. Muscovite is a potassium aluminium silicate hydroxide fluoride mineral that belongs to the mica group. Muscovite is a common rock forming mineral and is found in igneous, metamorphic and detrital sedimentary rocks.

An Important Point. Trying to buy Muscovite Mica Minerals from Nigeria through genuine sellers can lead to a lot of wasted time and efforts on the part of the Mica Minerals buyers.
Mica: Mica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic.
Mica minerals are major rock forming minerals found in gneiss, schist and granite. The mica group includes muscovite mica and biotite mica. They usually form in layers of sediment on ocean floors.
Muscovite, commonly known as white mica, is a member of the mica family of minerals. The mica minerals all share the property of perfect basal cleavage, which means that layers of mica can be peeled off of a mica crystal in very thin sheets. It is especially easy to peel off large numbers of paper-thin sheets from a muscovite crystal. Consequently, crystals of mica, like the one shown below ...
A series or subgroup of the Mica Group. The CNMMN Subcommittee on Nomenclature of the Micas (1998, 1999) has recommended that the name biotite be used for a series between the joins Annite-Phlogopite and Siderophyllite-Eastonite, and is therefore no longer to be regarded as a species name.
Mineral Resource of the Month: Mica Jason Christopher Willett, a mineral commodity specialist for the U.S. Geological Survey, compiled the following information on mica. Sheets of muscovite and biotite mica litter the ground at the Ruggles Mine in Grafton, N.H., where mica was discovered in 1803.
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 and in those earlier times did not always indicate ...
Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 - 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties.
Fuchsite Crystals... Have Sparkling Radiant Energy! Fuchsite is a lovely green form of Muscovite Mica. Held in the light, its amazing sparkle just seems to draw the eyes to it!
Fuchsite mica is a chromium rich variety of muscovite where chromium cations substitute for some of the octahedral aluminum in the muscovite crystal structure. The chromium impurities in fuchsite are responsible for its emerald green color.
The mica group of sheet silicate (phyllosilicate) minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towards pseudohexagonal crystals, and are similar in chemical composition.
Muscovite, also called common mica, potash mica, or isinglass, abundant silicate mineral that contains potassium and aluminum. Muscovite is the most common member of the mica group.
