If the rings of tetrahedra in one layer lie directly above the rings in adjacent layers, then they are related by a 90 ° translation and biotite must belong to the hexagonal crystal system. If the rings are offset in any direction, then biotite is monoclinic. Now rotate the structure so that you are looking ...
اقرأ أكثرWhat is Biotite? Biotite is yet another common group of sheet silicate minerals within the mica group found in a wide range of metamorphic rocks such as granites, pegmatites, peridotites, and other igneous rocks. Like muscovite, it is a sheet mineral of the mica group except it contains magnesium and potassium.

اقرأ أكثرBiotite is a 2:1 phyllosilicate mineral which comprises monoclinic minerals from the mica group and it forms various intermediary secondary clay minerals through the weathering process. Such type of weathering transformation in the lattice makes changes in the biotite interlayers like the release of K from lattice to soil solution and affects ...
اقرأ أكثرBiotite–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.
