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 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.

Properties Edit. 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 pinacoid termination.It has four prism faces and two pinacoid faces to form a pseudohexagonal crystal. Although not easily seen because of the cleavage .
