where is biotite mica found

Biotite - Wikipedia

What is Biotite? 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 chemical composition but are all sheet silicate minerals with very similar physical properties.

Biotite - Assignment Point

Biotite is a common rock-forming mineral, and is especially noted in metamorphic rocks such as schist and gneiss. It is also found in igneous rock such as granites and rhyolites. Biotite is also the primary mica in rare earth pegmatites. It is very hard to clean because if washed it will absorb water internally and start to break apart.

Muscovite in igneous rocks is usually associated with quartz, potassium feldspars, biotite and amphibole minerals. In pegmatites, beryl and tourmaline may be added to that list. Within metamorphic rocks, muscovite is typically found with other members of the mica group, such as biotite and chlorite.

Granite - Wikipedia

A granite containing both muscovite and biotite micas is called a binary or two-mica granite. Two-mica granites are typically high in potassium and low in plagioclase, and are usually S-type granites or A-type granites. Chemical composition.

Gneiss has thick lamellae and schist have very thin, fine layers. There are two kinds of schists found in the canyon, either a mica-rich schist, that has a lot of biotite and muscovite mica, or a schist rich in hornblende, a type of mineral called amphibole. A zone of schist crosses the canyon between Gunnison Point and Pulpit Rock Overlook.

Muscovite and Biotite
