Biotite Mineral Uses and Properties

What is Biotite? Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks.These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others.These micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

University of Minnesota’s Mineral Pages: Calcite

Muscovite in igneous rocks is usually associated with quartz, potassium feldspars, biotite and amphibole minerals. In pegmatites, beryl and tourmaline may be added to that list. Within metamorphic rocks, muscovite is typically found with other members of the mica group, such as biotite and chlorite.

Biotite Mica Mineral and Healing Properties

Biotite was named by J.F.L. Hausmann in 1847 in honour of the French physicist Jean-Baptiste Biot, who, in 1816, researched the optical properties of mica, discovering many unique properties. Interesting Facts. Biotite mica is sometimes called "iron mica" because it is more iron-rich than phlogopite.

Biotite Geology North

Biotite, a variety of mica, is common in most Cheviot igneous rocks. Whilst most of it is a primary mineral that crystallised out of the original melt, some of it is secondary, having been formed by the hydrothermal alteration of other primary minerals due to the circulation of hot fluids.

Biotite Wikipedia

Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3AlSi 3O 10(F,OH) 2. It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include siderophyllite and eastonite. Biotite was regarded as a mineral species by the International Mineralogical Associationuntil 1998, when its status was changed to a mineral group. The term biotite is still used to describe un
