Mica is a group comprising almost 30 members that differentiate from each other, primarily, by atom substitutions or vacancies in the crystal lattice. From an industrial standpoint, very few are mined: Muscovite, white mica, is by far the most common, Phlogopite - a dark brown mica - comes in second.

The common rock-forming micas are distributed widely. Biotite occurs in igneous rocks, pegmatite occurs in masses. During chemical weathering, it's usually rare in the sedimentary rocks and sediments. Also, biotite tends to lose its elasticity and become decolorized due to the appearance of greyish silver flakes.
