optical properties of biotite mineral

mica Structure, Properties, Occurrence, & Facts

Mica, any of a group of hydrous potassium, aluminum silie minerals. It is a type of phyllosilie, exhibiting a twodimensional sheet or layer structure. Among the principal rockforming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic.

Biotite mica mineral specimens – Best Crystals

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.
