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 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 Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals

Biotite Mica Mineral Physical and Optical 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.

Related minerals, biotite and phlogopite are end members of a ‘mineral series’. A mineral series consists of minerals that share the same crystal structure and only differ from one another in their relative proportions of a few key elements. As an example, magnesium and iron ions have the same charge and are roughly the same size, so they

Granite Wikipedia

Granite (/ ˈ ɡ r æ n ɪ t /) is a common type of felsic intrusive igneous rock that is granular and phaneritic in texture. Granites can be predominantly white, pink, or gray in color, depending on their mineralogy.The word "granite" comes from the Latin granum, a grain, in reference to the coarse-grained structure of such a holocrystalline rock. Strictly speaking, granite is an igneous rock
