Biotite Mineral | Uses and Properties
The name "biotite" is used in the field and in entry-level geology courses because these minerals generally cannot be distinguished without optical, chemical, or x-ray analysis.. Biotite is a rock-forming mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.It also forms under metamorphic conditions when argillaceous rocks are ...

Geochemical and Geochronological Discrimination of Biotite ...
The similar relative timing of these four biotite types makes it difficult to distinguish between the metamorphic and/or hydrothermal biotite. Based on the structural location of halo biotite, adjacent to pre to syn-D 2 veins, it is logical to assume a hydrothermal source, possibly related to the mineralizing event. However, the intergrown and ...

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.
