WebBiotite 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. WebMany minerals exhibit cleavage only on one side, and some may exhibit different quality cleavage on different crystal sides.
