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.

Mgrich biotite is also found in marble and related metamorphosed carbonaterich rocks. Biotite also is a relatively common detrital mineral, particularly in immature sediments, but yields to clay minerals with extended weathering and transport. Most vermiculite is a hydrated alteration product of biotite.

General considerations. Of the 28 known species of the mica group, only 6 are common rockforming minerals. Muscovite, the common lightcoloured mica, and biotite, which is typically black or nearly so, are the most abundant. Phlogopite, typically brown, and paragonite, which is macroscopically indistinguishable from muscovite, also are fairly common.
