Out of 28 known species of the mica group, only 6 of them are common rock-forming minerals. Muscovite, which is the common biotite and light-coloured mica, typically black or nearly so, are the abundant ones. Phlogopite, which is typically paragonite, and brown is macroscopically indistinguishable from the muscovite. They are also fairly common.

Mica is a mineral name given to a group of minerals that are similar in their physical properties and chemical compositions. They are all silicate minerals, which means that chemically they all contain silica (SiO 4 ). Mineralogists call micas sheet silicates because their molecules combine to form distinct layers.

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.
