Properties. Like other mica minerals, biotite has a highly perfect basal cleavage, and consists of flexible sheets, or lamellae, which easily flake 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

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 Mineral | Uses and Properties. What is Biotite? Biotite is a name used for a large group of black mica minerals that are commonly found in igneous and metamorphic include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many micas vary in chemical composition but are all sheet silicate minerals with very similar physical properties.

Mineral Group: Mica group . Association: Quartz, plagioclase, potassic feldspar, biotite, tourmaline, topaz . Diagnostic Features: Characterized by its highly perfect cleavage and light color. Distinguished from phlogopite by not being decomposed in sulfuric acid and from lepidolite by not giving a crimson flame. Physical Properties of Muscovite

Biotite usually occurs in brown to black, dark green variety. It is a name used for a range of black mica minerals with different chemical 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 is rarely considered a valuable mineral specimen, but it can accompany other minerals and compliment them. In Bancroft, Ontario Biotite forms large crystals with green apatite and hornblende. Single large plates or "books" of biotite can grow to considerable size and can make impressive mineral specimens. Weathered tiny crystals of biotite can appear golden yellow with a nice sparkle
WhatsAppعرض المزيدBiotite is a kind of mineral, which is named after the French physicist Jean Baptist. He researched and studied about the stone for its ophthalmic properties. This stone is also known as the black mica. Commonly, it occurs in golden brown, rust, brown, reddish brown, and dark brown colors. Further, it forms a shape of a lens when it gets heated by the sun, as well as expands outwardly.

The names of the rockforming micas constitute a good example of the diverse bases used in naming minerals: Biotite was named for a person—JeanBaptiste Biot, a 19thcentury French physicist who studied the optical properties of micas; muscovite was named, albeit indirectly, for a place—it was originally called "Muscovy glass" because it came from the Muscovy province of Russia

· Also, the tenacity of biotite is brittle to flexible. It has a vitreous to pearly lustre. The mineral streak of biotite is white. Moreover, its optical properties can vary from transparent to translucent to opaque. The mineral is also useful in determining the age of rocks and in assessing the temperature history of metamorphic rocks.

Anisotropic minerals have different properties indifferent directions. So, light travels through them in different ways and with different velocities, depending on the direction of travel through a grain. Isotropic and anisotropic minerals are, most of the time, easily distinguished because isotropic minerals do not transmit light (are always black) when viewed under XP light. A complication

The most common minerals in Earth''s crust can often be identified in the field using basic physical properties such as color, shape, and hardness. The context of a mineral is important, too – some minerals can form under the same conditions, so you are likely to find them in the same rock, while others form under very different conditions and will
