Jean Baptiste Biot [April 21, 1774 Paris, France - February 3, 1862 Paris, France]
Member of:
Name:
Named in 1847 by Johann Friedrich Ludwig Hausmann in honour of the French physicist, mathematician, meteoriticist, astronomer, and mineralogist, Jean-Baptiste Biot [April 21, 1774, Paris, France - February 3, 1862, Paris, France], who studied the optical properties of the micas. Biot and his associate, Félix Savart, discovered that an electric current in a wire produced a magnetic field. Biot received many awards in his lifetime in recognition of the value of his scientific researches.
A series or subgroup of the Mica Group.

The CNMMN Subcommittee on Nomenclature of the Micas (1998, 1999) has recommended that the name biotite be used for a series between the joins Annite-Phlogopite and Siderophyllite-Eastonite, and is therefore no longer to be regarded as a species name. Fluorophlogopite and Fluorotetraferriphlogopite should be included. The name is most commonly used for the micas on the Fe-rich end of the series, including Annite, Fluorannite, Tetra-ferri-annite and Siderophyllite.

The name "biotite" is also used as a generic field term for any incompletely analysed dark mica.
