Biotite Facts

Biotite Facts

Biotite is group of common rock-forming minerals found in igneous and metamorphic rocks. It is a name used for a large group of black mica minerals which include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. The micas vary in chemical composition but have very similar physical properties and are all sheet silicate minerals.

Biotite. Biotite or black mica is a member of the mica group within the sheet silicates. Its general formula is K(Mg,Fe) 3 (AlSi 3 O 10)(OH) 2.Biotite is usually a solid solution of several minerals, mostly Fe-rich annite, KFe 3 (AlSi 3 O 10)(OH) 2, and Mg-rich phlogopite, KMg 3 (AlSi 3 O 10)(OH) 2; the exact composition of a sample is variable and has to be determined through a thorough analysis.

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible. Mica is heat-resistant and does not conduct electricity.
