THE MINERAL MICA Mica is the name given to a group of silicate minerals that have silicon and oxygen as their two major components. The Mica family of minerals includes several variations based on chemical composition and characteristics, the most common being thin crystal layers of sheets that peel off in thin transparent layers.
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.
Lepidolite is an uncommon mica and has only in the past decade become available on the mineral market in large quantities. It is stone of calm, trust, and acceptance. It has a strong relaxing, balancing and calming effect.

Mica powder is a non-metallic mineral, containing a variety of components, mainly SiO2, the content is about 49%, and the content of Al2O3 is about 30%.
Biotite is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2. More generally, it refers to the dark mica series, primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite.

University of Waterloo Earth Sciences Museum Collection Sodalite is a vibrantly blue mineral which was named for its high sodium content (sodium is in table salt!) It has a greasy lustre, which means that if you can get a good look at a clean crystal then it will look like the surface of the mineral is greasy.
The mica minerals are distinguished by their perfect basal cleavage, which means that they are easily split into thin, often transparent, sheets. Two micas, biotite, and muscovite, are so common that they are considered rock-forming minerals .

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.
What is Biotite? Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others.

Mica is from the silicate class of minerals. Mica is the only mineral that can be bent without breaking. This is because it can be peeled into very thin sheets.
The Mineral Mica: Mica is a generic name for a group of silicate minerals which, have chemical as well as physical traits. They are also referred to as sheet silicates since they occur in layers, each layer separate and distinct from the other.
Mica is a silicate mineral that can be found in nature as metamorphic or igneous rocks. Mica can also be found in sedimentary rocks depending on the types of minerals left behind by water and what minerals are in the area.
