Is biotite metamorphic
WebBiotite is group of common rock-forming minerals found in igneous and metamorphic rocks. It is a name used for a large group of black mica minerals which include annite, phlogopite, siderophyllite, fluorophlogopite, fluorannite, eastonite, and many others. The micas vary in chemical composition but have very similar physical properties and are all … WebBiotite was named by Johann Friedrich Ludwig Hausmann in 1847. He gave the name in honor of the French physicist Jean-Baptiste Biot, who discovered the optical properties of …

WebIn regional metamorphism, cordierite is formed only in environments where pressures are high and uniform. In these environments, the pre-existing minerals such as kyanite and biotite, become unstable reacting to give cordierite: 1) muscovite + biotite = alkali feldspar + cordierite + garnet 2) biotite + aluminosilicate = cordierite + spinel WebMetamorphic minerals that grow under differential stress will have a preferred orientation if the minerals have atomic structures that tend to make them form either flat or elongate crystals. This will be especially apparent for micas or other sheet silicates that grow during metamorphism, such as biotite, muscovite, chlorite, talc, or serpentine.
