Biotite Mineral Geology and Uses Biotite is a mineral found in many rocks, but you may not recognize its name because it's often lumped together with other related minerals under the name "mica"Mica is a group of phyllosilicates or sheet silicates characterized by forming parallel sheets of silicate tetrahedrons composed of silicon oxide, Si 2 O 5Various forms of mica have different chemical compositions and some unique .

YupRocks - Pictures of the Mineral Biotite The Mineral Biotite (Mica) Biotite belongs to the mica group and is a Common Phyllosilicate Mineral In a wider perspective, it refers to the darker group of mica, mainly a chain of solid solution in between the Magnesium-Endmember Phlogopite and the Iron-Endmember Annite; Siderophyllite being a part of most of the Aluminous Endmembers
Biotite: Mineral information, data and localiti 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

Biaxial Minerals - Tulane University Biaxial Positive A mineral is biaxial positive if β is closer to α than to γ; In this case the acute angle, 2V, between the optic axes is bisected by the γ refractive index direction Thus we say that γ is the acute bisectrix (BX A), because it bisects this angle; If a table of optical properties of minerals reports the 2V angle, it usually refers to this acute angle
