Muscovite mica: The mineral Muscovite information and pictures
Muscovite is an extremely common mineral, nevertheless there are some exceptional localities that need to be mentioned. Outstanding Muscovite crystals, some bright yellow and others with perfect star formations, come from the famous pegmatite localites in the Doce and Jequitinhonha Valleys in Minas Gerais Brazil. Specific localities include Divino das Laranjeiras ("stars"),Galileia, Governador ...

Phyllosilicates – (Silicate Sheets)
In muscovite there is the following coupled substitution: (Mg,Fe2+)[VI]+ Si[IV] ↔Al[VI] + Al [IV] Leading from KAl 2 (AlSi 3 O 10)(OH) 2 to K(MgFe) 2 (Si 4 O 10)(OH) 2. This is the so called phengite substitution and indicates increasing pressure. The breakdown of …

Biotite Mineral | Uses and Properties
The name "biotite" is used in the field and in entry-level geology courses because these minerals generally cannot be distinguished without optical, chemical, or x-ray analysis.. Biotite is a rock-forming mineral found in a wide range of crystalline igneous rocks such as granite, diorite, gabbro, peridotite, and pegmatite.It also forms under metamorphic conditions when argillaceous rocks are ...

Sillimanite nodule in a biotite gneiss. The sillimanite grew by the reaction muscovite + quartz = sillimanite + K-feldspar + H 2 O. Small amounts of muscovite in the foliation are still present, so the reaction did not run to completion. Microcline and quartz can also be distinguished in the image, so this represents the reaction assemblage.

Of the 28 known species of the mica group, only 6 are common rock-forming minerals. 1) Muscovite, (Potassium Mica) the common light-colored mica. It was originally called "Muscovy glass" because it came from the Muscovy province of Russia. 2) Biotite, (Magnesium Iron Mica) which is typically black or nearly so, is the most abundant.

How Can You Tell Biotite?
How might you distinguish Muscovite from biotite in a thin section? The mica minerals have one perfect cleavage that allows them to be broken into very thin sheets. This is very distinctive. Muscovite is clear, silvery, or coppery silver in color (depending on the thickness of the sample and presence of impurities) whereas fresh biotite is black.

Biotite is another common mica mineral with a single perfect cleavage similar to that of muscovite. The two often occur together in the igneous and metamorphic rocks, but they can be distinguished by their color. Muscovite is very light colored to colorless, while biotite is much darker typically brown to black.
