    Mica Minerals are Major Rock Forming Minerals

    Mica Minerals are Major Rock Forming Minerals. Mica minerals are major rock forming minerals found in gneiss, schist and granite. The mica group includes muscovite mica and biotite mica. They usually form in layers of sediment on ocean floors. Weathering of continental rocks breaks large and small chunks of rock off the larger older rocks.

    The mica group of sheet silicate phyllosilicate minerals includes several closely related materials having nearly perfect basal cleavage. All are monoclinic, with a tendency towardsdohexagonal crystals, and are similar inposition. The nearly perfect cleavage, which is the most prominent characteristic of mica, is explained by the hexagonal sheet like arrangement of its atoms.
