Biotite mica: The mineral Biotite information and pictures

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 ...

Biotite Mineral Geology and Uses

Biotite is a dark-colored mica. It is an aluminosilicate mineral that forms sheets or flakes. Although biotite is sometimes called black mica, it occurs in other colors, including brown, greenish-brown, yellow, and even white. Biotite occurs with other types of mica, even within a single rock.
