Muscovite Mineral | Uses and Properties
Muscovite is the most common mineral of the mica family. It is an important rockforming mineral present in igneous, metamorphic, and sedimentary rocks. Like other micas it readily cleaves into thin transparent sheets. Muscovite sheets have a pearly to vitreous luster on their surface.

Biotite Geology North
Biotite, a variety of mica, is common in most Cheviot igneous rocks. Whilst most of it is a primary mineral that crystallised out of the original melt, some of it is secondary, having been formed by the hydrothermal alteration of other primary minerals due to the circulation of hot fluids.

Accessory mineral | Britannica
Accessory mineral, any mineral in an igneous rock not essential to the naming of the it is present in small amounts, as is common, it is called a minor accessory. If the amount is greater or is of special significance, the mineral is called a varietal, or characterizing, accessory and may give a varietal name to the rock (, the mineral biotite in biotite granite).

It is named in honor Jean Baptiste Biot (1774 1862), a French physicist, mathematician, and astronomer who researched the mica minerals for their optical properties. Because of Biotite's abundance, its presence is usually lacking in collections except for it being an accessory mineral to other minerals.

Feb 25, 2019· Other minerals, however, are added as the rock undergoes different "zones" of metamorphosis. The minerals are added in the following order: biotite, garnet, staurolite, kyanite, sillimanite. If a piece of mudrock contains garnet but no kyanite, it has probably undergone only a low grade of metamorphosis.
