Mica is a metamorphic mineral. The many variations come from the diverse ways it formed. Mica formations are associated with volcanoes and hydrothermal vents. The most easily recognizable characteristic of mica are the thin crystal layers. With many micas the sheets peel off in thin transparent layers due to mica's perfect cleavage.

Other minerals present in shale are quartz, mica, pyrite, and organic matter. Shale forms in very deep ocean water, lagoons, lakes and swamps where the water is still enough to allow the extremely fine clay and silt particles to settle to the floor. Geologists estimate that shale represents almost ¾ of the sedimentary rock on the Earth's crust.
Biotite (pictured to the left) is a black or brown mica; muscovite is light-colored or clear mica. Mica is so soft (2.5 on Mohs scale) that it can be scratched with a fingernail. Mica typically occurs in metamorphic and igneous rocks. Biotite and muscovite are two of the primary minerals in the metamorphic rocks at:
