The Mineral Biotite (Mica)

Biotite was named after Jean Baptiste Biot (1774 1864) the French physicist, who researched the optical properties of mica. Occurrence A major class of black mica minerals often identified in the metamorphic and igneous rocks is named as Biotite .

Biotite

Primary biotite crystals commonly contain many inclusions of magnetite along with accessory minerals like apatite and zircon. Since secondary biotite is generally free from inclusions of minerals other than magnetite, this feature helps to distinguish between the two.
