Muscovite – Virtual Museum of Molecules and Minerals

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 …
