Biotite

Biotite, usually dark green, brown, or black, has a pale brown color under plane-polarized light in this sample. It exhibits high interference colors in cross-polar light just as muscovite, but has a lower birefringence than muscovite. Biotite shows parallel extinction in cross polarized light, and has perfect cleavage in one direction.

Biotite – Virtual Museum of Molecules and Minerals

Biotite–K(Mg,Fe)3AlSi3O10(OH)2–is a dark, iron-rich mica that has a monoclinic crystal system. The octahedral layer is entirely occupied by Mg2+ and Fe2+ and the mineral is therefore ctahedral, since all octahedra are occupied. The source of the lattice charge is the presence of Al3+ in place of Si4+ in 1/4 of the tetrahedral sites.
