Granite: Igneous Rock

Granite is a light-colored igneous rock with grains large enough to be visible with the unaided eye. It forms from the slow crystallization of magma below Earth's surface. Granite is composed mainly of quartz and feldspar with minor amounts of mica, amphiboles, and other minerals. This mineral composition usually gives granite a red, pink, gray ...

Muscovite

The following observations of workers on muscovite are important: (i) "celadonite"-bearing muscovite has larger lateral spacing (b o) than celadonite-free muscovite; b o value is controlled mainly by the content of Fe +2, Fe +3, and Mg and to a lesser extent by alkali content in muscovite (Guidotti and Sassi, 1976), (ii) basal spacing d (002) in 2M …

Biotite mica: The mineral Biotite information and pictures

Biotite is a very common form of mica. 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.
