WebBiotite is a common phyllosilicate mineral within the mica group. Its approximate chemical formula is K (Mg, Fe) 3 AlSi 3 O 10 (F, OH) 2. This mineral is usually dark green to brown or black. It can be transparent to opaque, has a vitreous to pearly luster, and a gray-white streak. When weathered, its crystals appear sparkly yellow and are ... WebIt is a high-grade metamorphic rock in which mineral grains recrystallized under intense heat and pressure. This alteration increased the size of the mineral grains and segregated them into bands, a transformation which …
WebBiotite, also known, as ‘black mica’ is a rock-forming femic phyllosilicate that occurs in several igneous and metamorphic rocks. The mineral was named in honor of the French scientist Jean-Baptiste Biot, who devoted his life to study the optical properties of the micas. Structure and chemistry WebGranite: the most common igneous plutonic rock. Contains essential quartz, plagioclase and alkali feldspar, usually with hornblende and/or biotite and/or muscovite. Granodiorite: a plutonic rock with essential quartz and plagioclase, with lesser amounts of alkali feldspar and small amounts of hornblende and biotite.
Biotite is a common group of phyllosilicate minerals within the mica group, with the approximate chemical formula K(Mg,Fe)3AlSi3O10(F,OH)2. It is primarily a solid-solution series between the iron-endmember annite, and the magnesium-endmember phlogopite; more aluminous end-members include … Meer weergeven 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 Meer weergeven Biotite is used extensively to constrain ages of rocks, by either potassium-argon dating or argon–argon dating.
