Biaxial Minerals Tulane University

Biaxial Minerals. Just like in uniaxial minerals, if one is looking down one of the optic axes, light traveling along the optic axis will be vibrating in the β direction, and thus the mineral would be extinct for all rotation positions. The three principal planes of the biaxial indicatrix are shown here.

Biotite – Virtual Museum of Molecules and Minerals

Biotite–K(Mg,Fe)3AlSi3O10(OH)2–is a dark, ironrich mica that has a monoclinic crystal system. The octahedral layer is entirely occupied by Mg2+ and Fe2+ and the mineral is therefore trioctahedral, 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.
