Biotite Mineral | Uses and Properties

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 stone composition but are all sheet silicate minerals with very similar physical properties.

Biotite usually occurs in brown to black, dark green variety. It is a name used for a range of black mica minerals with different stone compositions but with very similar physical properties. These minerals are usually indistinguishable from each other without laboratory analysis. There is a small list of biotite minerals that were down.

Biotite - Wikipedia

Like other mica minerals, biotite has a highly perfect basal cleavage, and consists of flexible sheets, or lamellae, which easily flake off. It has a monoclinic crystal system, with tabular to prismatic crystals with an obvious pinacoid termination. It has four prism faces and two pinacoid faces to form a pseudohexagonal crystal. Although not easily seen because of the cleavage and sheets, fracture is uneven. It appears greenish to brown or black, and even yellow when weathered. It can be transparent to opaque, has a vit…

Biotite mica: The mineral Biotite information and pictures

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 being an accessory mineral to other minerals ...

Biotite Mineral Geology and Uses -

Biotite is a dark-colored mica. It is an aluminosilicate mineral that forms sheets or flakes. Although biotite is sometimes called black mica, it occurs in other colors, including brown, greenish-brown, yellow, and even white. Biotite occurs with other types of mica, even within a single rock.

Jul 06, 2018 · Biotite Properties. Biotite is mostly found in various crystalline igneous rocks like pegmatite, peridotite, gabbro, diorite, and granite. Biotite transforms to clay minerals and is not very resistant to weathering, which is why it can also be found in sandstones and sediments. This mineral is very easy to identify.
