Biotite mica is black or dark brown, sometimes with light red, light green or other tones. Black biotite mica is resistant to corrosion. welcome to contact us . Color is the only easy way to distinguish them from one another and other micas like muscovite Biotite is a mineral found in many rocks, but you may not recognize its name because it's often lumped together with other related minerals under the name mica.Mica is a group of phyllosilicates or sheet silicates characterized by forming parallel sheets of silicate tetrahedrons composed of silicon oxide, Si 2 O 5.Various forms of mica have different chemical compositions and some unique. Biotite - K(Mg,Fe 2+) 3 [AlSi 3 O 10 (OH,F) 2 Biotite is a common phyllosilicate mineral within the mica group. Biotite is a solid solution between the end members phlogopite KMg 3 AlSi 3 O 10 (OH) 2 and annite KFe 3 AlSi 3 O 10 (OH) 2, although pure annite does not occur in nature.In addition, small amounts of Na, Rb, Cs, and Ba may substitute for K, and like in other minerals, F can.

Biotite in brown and muscovite in an orthogneiss thin section under plane polarized light Biotite is included in the silicates group because the composition contains silica. It is also apart of the phyllosilicates because it contains water, or hydroxyl atoms, that bond each layer of the sheets together (4). All together, biotite is a member of the mica group due to its one perfect cleavage that allows the mineral to peel into sheets.

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

It appears in the form of thin sheets which generally range from 0.003 mm to 0.1 mm in thickness. Uses. The high iron content, which imparts dark colors, rules out biotite from many industrial uses . The original parent rock (or protolith) of mica schist is shale. Phyllite could also be considered the parent rock as mica schist is a more highly metamorphosed phyllite
Micas have a layer charge of about 1.0 per half-cell formula unit and are both dioctahedral, e.g., muscovite and paragonite, and trioctahedral, e.g., biotite, phlogopite, and lepidolite (Table 2.4). With the exception of paragonite, a Na-bearing mica, the other micas have K + in the interlayer positions to satisfy the negative charge resulting from isomorphous substitution Biotite definition is - a generally black or dark green form of mica that is a constituent of crystalline rocks and consists of a silicate of iron, magnesium, potassium, and aluminum
