biotite mineral properties

Mining Funda: Biotite

Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic rocks. These include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. These micas vary in chemical composition but are all sheet silie minerals with very similar physical properties.

Adjacent mineral deposits and the large clay pits were also the result of the hydrothermal fluid circulation surrounding the SW England pluton during its intrusion in the Permian period. The thin section contains large plates of biotite showing alteration to chlorite, with lesser amounts of equally sized muscovite.

Biotite Optical Mineralogy

Biotite is actually a Silie mineral. Biotite was named by J F L Hausmann in the year 1847. It was named in honor of Jean Baptiste Biot, a French physicist who discovered the optical properties of micas in the year 1816. Biotite mineral crystals are known to crystallize in the monoclinic system the monoclinic system.

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
