Named in 1847 by Johann Friedrich Ludwig Hausmann in honour of the French physicist, mathematician, meteoriticist, astronomer, and mineralogist, JeanBaptiste Biot [April 21, 1774, Paris, France February 3, 1862, Paris, France], who studied the optical properties of the micas.

This study addresses the hydrothermal alteration and mineralization related to a system of tourmalinequartz veins intersecting biotitegranite in Nanjizal, in the Land s End granites of the cornubian batholith. ...
Biotite and/or hornblende granite gneiss locally pyroxenic; commonly with subordinate leucogranitic gneiss, biotitequartzplagioclase gneiss, other metasedimentary rocks, amphibolite, migmatite. Amphibolite with porphyroblasts of Kfeldspar locally prominent in northwest Adirondacks.
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 a member of the mica branch of the silicate mineral is common as a rockforming mineral and is found associated with muscovite, feldspar, and quartz. It has a widespread occurance and is present in all three rock types igneous, metamorphic, and sedimentary.
Biotite granite is a coarse grained variation of granite, composed of quartz, feldspar and biotite. These samples were collected from Scotland and are offered in a variety of sizes. An ideal sample for education use or for rock collectors and amateur geologists.
This paper reports on the results of studies of the carbonate–fluoride isolations with extremely high Y and REE concentrations from biotite–arfvedsonite granite of the Katugin rare metal deposit.
Granite is a general commercial term for decorative building stone that is hard and crystalline. Commercial granite may include granite, gneiss, syenite, monzonite, granodiorite, anorthosite, or larvikite or any phaneritic igneous or metamorphic rock.

Biotite in granite tends to be poorer in magnesium than the biotite found in its volcanic equivalent, rhyolite. Biotite is an essential phenocryst in some varieties of lamprophyre. Biotite is occasionally found in large cleavable crystals, especially in pegmatite veins, as in .
Biotite itself is a type of mica, and it is also known internationally under the following names: iron mica, lepidomelane, manganophyllite, micaceous iron ore and oxybiotite. also states that biotite contains atoms of potassium, magnesium, aluminum, iron, silicon, hydrogen, oxygen and fluorine.

The granitepegmatite systems of the Bastar craton, central India host polymetallic Nb,Ta,Sn,Be,Li ore deposits, which are genetically related to various granitic bodies locally called the Paliam, Darba, Metapal and Kawadgaongranites. In addition, limited occurrences of Rare Earth Elements (REE) are also known. Generally, the granites and associated pegmatite aureoles locally show physical ...
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 word "granite" comes from the Latin granum, a grain, in reference to the coarsegrained structure of such a holocrystalline rock. Strictly speaking, granite is an igneous rock ...
Jul 15, 2019· The Shimensi tungsten polymetallic deposit, situated in the Dutang ore field, South China, is one of the largest tungsten deposits in the world, with an estimated WO 3 reserve of million tons. Coarsegrained porphyritic biotite granite (CPBG), finegrained porphyritic biotite granite (FPBG), finegrained biotite granite (FBG) and biotite granite porphyry (BGP) are all orerelated, but ...

The name "biotite" is used in the field and in entrylevel geology courses because these minerals generally cannot be distinguished without optical, chemical, or xray analysis. Biotite is a rockforming mineral found in a wide range of crystalline igneous rocks such as granite.
Granite is a crystalline igneous rock that consists largely of feldspar and two are the most common minerals in the crust which means that granite too is among the most ubiquitous rock types, especially in the upper continental crust.. This picture of a granite pegmatite from northern Norway (Nyelv) is very coarsegrained for a normal granite and compositionally simpler than most ...
Specific gravity of some common minerals and other materials
Biotite and muscovite are the two most common mica minerals that often occur together in Alrich igneous rock. Peraluminous twomica granitoid. A fragment from an erratic on Alnö Island, Sweden. Width of sample 9 cm. Monomineralic rock that is composed of (almost) pure biotite is .
It is a common component of many magmatic and metamorphic rocks such as granite, syenite, diorite, gabbro, basalt, andesite, gneiss and schist. It is the main mineral of amphibolites. Very dark brown to black hornblendes containing titanium are normally called basaltic hornblendes, as they are usually a component of basalt and related rocks.
Granite is a lightcolored plutonic rock found throughout the continental crust, most commonly in mountainous areas. It consists of coarse grains of quartz (1050%), potassium feldspar, and sodium feldspar. These minerals make up more than 80% of the rock. Other common minerals include mica (muscovite and biotite) and hornblende (see amphibole).
