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 silicate minerals with very similar physical properties.

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 Biotites abundance, its presence is usually lacking in collections except for it
Jan 16, 2020 Biotite is a mineral found in many rocks, but you may not recognize its name because its 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 5.Various forms of mica have different chemical compositions and some unique ...

Feb 24, 2021 Pioneer plants play an important role in eco-engineering Fe ore tailings into soil for sustainable mine site rehabilitation. However, root-driven mineral weathering and secondary mineral formation remain poorly understood in tailings, despite being prerequisites for aggregate formation and pedogenesis. The present study aimed at characterizing the direct role of plant roots in tailing mineral ...

Apr 22, 2020 What is biotite cleavage? Like other mica minerals, biotite has a highly perfect basal cleavage, and consists of flexible sheets, or lamellae, which easily flake off. The color of biotite is usually black and the mineral has a hardness of 2.53 on the Mohs scale of mineral hardness. Click to see full answer.

Biotite is also common in metamorphic rocks where it is a frequent component of schists, gneisses and phyllites. Biotite survives a certain amount of weathering and is found in soils, sediments and sedimentary rocks. Weathered biotite becomes relatively brassy of bronzy in color and has been mistaken for gold.
