The general formula for the mica minerals is XY 2-3 [(Si,Al) 4 O 10](OH,F) 2, where X = K,Na,Ca and Y = Mg,Fe,Li,Al. Their molecular makeup consists of double sheets of strongly joined silica units (SiO 4 ) that sandwich between them a …

Mica is a mineral name given to a group of minerals that are physically and chemically similar. They are all silicate minerals, known as sheet silicates because they form in distinct layers. Micas are fairly light and relatively soft, and the sheets and flakes of mica are flexible.

Micas occuring as large crystals are often called books; these may measure up to several metres across. In most rocks, micas occur as irregular tabular masses or thin plates (flakes), which in some instances appear bent.

The mica group represents 37 phyllosilicate minerals that have a layered or platy texture. The commercially important micas are muscovite and phlogopite. Layering in the univalent (potassium, sodium), or true, micas imparts perfect basal cleavage, allowing crystals to be split into very thin sheets that are tough and flexible.

There are several varieties of mica, but the three primary varieties are, muscovite, a hydrated silicate of aluminum and potassium; phlogopite, which is a magnesium bearing mica; and biotite, a ferro-magnesium variety. The world's chief …
