Muscovite. Muscovite, KAl 2 (AlSi 3)O 10 (OH,F) 2, has a monoclinic crystal system with a tabular habit.The octahedral layer is occupied by Al 3+ and the mineral is therefore dioctahedral, since two-thirds of the octahedra are occupied. The source of the lattice charge is the presence of Al 3+ in place of Si 4+ in 1/4 of the tetrahedral sites. The …

— Muscovite is a common mineral that belongs to the mica group. It is a silicate mineral that is characterized by its thin, sheet-like structure. Muscovite is composed of potassium (K), aluminum (Al), silicon (Si), and oxygen (O) atoms arranged in sheets, and it is known for its excellent cleavage, which allows it to be easily split into thin, flexible sheets.
