Only six of the 28 known mica species are common rock-forming minerals. The most common are muscovite, a common light-colored mica, and biotite, which is generally black or almost so. Phlogopite, which is generally brown, and paragonite, which is macroscopically identical to muscovite, are also very common. Lepidolite is a pinkish to lilac mineral found in lithium-bearing pegmatites. Glauconite, a green variety with different overall macroscopic properties than the other micas, appears infrequently in various marine sedimentary layers. Except for glauconite, all of these micas display easily visible flawless cleavage into flexible sheets.
Glauconite, which is most commonly seen as pelletlike grains, has no discernible cleavage. The names of the rock-forming micas are a good example of the various bases used in mineral naming: Biotite was named after a person, Jean-Baptiste Biot, a 19th-century French physicist who researched the optical characteristics of micas; muscovite was named, albeit inadvertently, after a location, because it originated in Russia’s Muscovy region.
