mica | Structure, Properties, Occurrence, & Facts | Britannica

mica, any of a group of hydrous potassium, aluminum silicate minerals. It is a type of phyllosilicate, exhibiting a two-dimensional sheet or layer structure. Among the principal rock-forming minerals, micas are found in all three major rock varieties—igneous, sedimentary, and metamorphic. Of the 28 known species of the mica group, only 6 are common rock-forming minerals. Muscovite, the ...

Biotite Facts - Softschools

Biotite 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 sheet silicate minerals.

Because of Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals. Biotite can come in enormous crystal sheets that can weigh several hundred pounds. Thin sheets can be peeled off as layers, and the thinner a layer is peeled the greater its transparency becomes.
