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. Below are just three of at least 11 common variations: Biotite. muscovite.
Mica minerals are really important, they make up 5% of the Earth's crust. They occur in many different rock types. Muscovite is a common mineral in felsic igneous rocks (mostly plutonic). It could also be an alteration product of other silicates, mostly feldspars (in this case it is usually called sericite).
Mica is the term for a large group of sheet silicates that can be parted into flexible or brittle sheets. Includes the True Micas or Common Micas (with monovalent interlayer cations, e.g. muscovite, paragonite, ephesite) and the Brittle Micas (with divalent interlayer cations, e.g. margarite, clintonite).Also known as the "mica family".
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. If they are held up to the light, they are transparent and ...
Mica, which is essentially a compound of silicate minerals, is comprised of closely related materials that have perfect basal cleavage. They belong to the category of principal rock-forming minerals and are found in various categories like sedimentary, igneous, and metamorphic.

Mica is a type of silicate formed as paper-thin layers built upon each other in formations that include flat angular blades, rosettes or hexagonal columns. Mica is a metallic material since it contains reactive element metals like potassium, lithium and aluminium. For this reason, mica can feel cold to the touch.
The mica group includes 37 phyllosilicate minerals. Mica splits into definite crystallographic structural planes. It is the most prominent characteristic of mica which is explained by the hexagonal sheet-like arrangement of its atoms.
