Biotite is a member of the mica branch of the silicate mineral is common as a rockforming mineral and is found associated with muscovite, feldspar, and quartz. It has a widespread occurance and is present in all three rock types igneous, metamorphic, and sedimentary.
Empirical Formula: KAl 3 Si 3 O 10 (OH) F : Environment: Granites and pegmatites. IMA Status: Valid Species (PreIMA) 1850 : Locality: Common world wide. Link to Location Data. Name Origin: From Muscovy glass, alluding to the Russian province of Muscovy. Name Pronunciation: Muscovite + Pronunciation : Synonym: Binnite (Ba ...
Biotite is one of the two most common members of the mica group. The other one is muscovite. Biotite with other micas are sheet silicates – their structure is composed of many sheetlike layers which are connected to eachother by weak chemical bonds. That gives rise to the most characteristic feature of micas: perfect basal cleavage.
There are various forms of mica, including muscovite, lepidolite, biotite and phlogopite. The chemical formula for Muscovite Mica, the most common form, is KAl3Si3O10(OH)2 (please note, .

Biotite is structurally related to the micaceous aluminosilicates. Its chemical formula is K(Mg, Fe) 3 AlSi 3 O 10 (OH,F) 2. The color of the thin sheets is from blackishbrown to brownishgreen. Biotite occurs widely as a rockforming mineral in igneous and metamorphic rocks. The largest biotite crystals, reaching 1– m, are found in ...
Aug 12, 2019· What is Biotite? Biotite is a phyllosilicate mineral that mainly contains magnesium and potassium. Moreover, its chemical formula can be given as K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) 2. Also, this is a sheet silicate. The sheets weakly bind to each other via potassium ions.
biotite mineralbiotite mineral; biotite mineral; Biotite is the most common mica mineral and also known as black mica, a silicate mineral in the common mica chemical formula K (Mg, Fe). It can be found in massive crystal layers weighing several hundred pounds.
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe) 3 AlSi 3 O 10 (F,OH) is primarily a solidsolution series between the ironendmember annite, and the magnesiumendmember phlogopite; more aluminous endmembers include siderophyllite and was regarded as a mineral species by the International ...
The high iron content, which imparts dark colors, rules out biotite from many industrial uses. However, because biotite is abundant in granitic rocks, pegmatites, and schists that are also associated with the more desirable muscovites, the mineral is important for exploration. Biotite is .
Biotite, the more abundant of the two minerals, is the ironrich end member of the series while phlogopite is the magnesiumrich end member. ^ Top. Geologic Setting and Associated Minerals. An important rockforming mineral in felsic and intermediate igneous rocks, biotite .
Biotite definition, a very common mineral of the mica group, occurring in black, darkbrown, or darkgreen sheets and flakes: an important constituent of igneous and metamorphic rocks. See more.
The name "biotite" is used in the field and in entrylevel geology courses because these minerals generally cannot be distinguished without optical, chemical, or xray analysis. Biotite is a rockforming mineral found in a wide range of crystalline igneous rocks .
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 heatresistant and does not conduct electricity.
Biotite is a very common form of mica. It is named in honor Jean Baptiste Biot (1774 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotite''s abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals ...

No matter how dark muscovite gets, fresh biotite is distinctly darker. These sheets of biotite are as thin as in the first muscovite photo above, but they are black and shiny, not silvery and shiny. This large book of biotite (~ 6" across) shows the 6sided shape of perfect biotite crystals. There is .

As nouns the difference between biotite and phlogopite is that biotite is (mineral) a dark brown mica; it is a mixed aluminosilicate and fluoride of potassium, magnesium and iron while phlogopite is (mineralogy) a mica mineral with the chemical formula k]]mg 3 alsi 3 o 10 (f,o[[hydrogen|h) 2, a basic potassium magnesium aluminosilicate, used as an insulator.
Biotite mica can have iron and/or magnesium in it and that makes it a ferromagnesian silicate mineral (like olivine, pyroxene, and amphibole).In muscovite mica, the only cations present are aluminum and potassium; hence it is a nonferromagnesian silicate mineral.
