  • 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 solidsolution series between the ironendmember annite, and the magnesiumendmember phlogopite; more aluminous endmembers 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 unBiotite is regarded as a mixture composed of variable proportions of four basic aluminosilicates of potassium, iron, magnesium, or aluminum: annite, K 2 Fe 6 (Si 6 Al 2 O 2 0)(OH) 4; siderophyllite, K 2 Fe 5 Al(Si 5 Al 3 O 2 0)(OH) 4; phlogopite, K 2 Mg 6 (Si 6 Al 2 O 2 0)(OH) 4; and eastonite, K 2 Mg 5 A1(Si 5 Al 3 O 2 0)(OH) 4 Biotite is arbitrarily designated as having a magnesiumtoiron ratio less Biotite mineral Britannica  Biotite is the most common mica mineral and also known as black mica, a silicate mineral in the common mica group Approximate chemical formula K (Mg, Fe) It can be found in massive crystal layers weighing several hundred pounds It is abundant in metamorphic rocks (both regional and contact),Biotite Mica Mineral Physical and Optical Properties Chemical Composition: Biotite is K(Mg,Fe) 3 AlSi 3 O 10 (OH) 2 Potassium iron magnesium aluminum silicate hydroxide Phlogopite is KMg 3 AlSi 3 O 10 (OH) 2 Potassium magnesium aluminum silicate hydroxide: Color: Biotite is typically brown to black while phlogopite is pale yellow to golden brown Both can be separated into thin translucent sheets, although phlogopite sheets will transmit University of Minnesota’s Mineral Pages: BiotiteBiotite Biotite is a common phyllosilicate mineral within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2More generally, it refers to the dark mica series, primarily a solidsolution series between the ironendmember annite, and the magnesiumendmember phlogopite; more aluminous endmembers include siderophylliteWhat is biotite?
