System:MonoclinicColour:White to colorless, ...
Hardness:2½
Name:The name was first used in 1850 by Dana and is derived from the term "Muscovy glass," which was in common use at that time; it is in reference to the Muscovy Province in Russia.


Mica Group

The most common of the Mica Group minerals, it is typically found as massively crystalline material in "books" or in flaky grains as a constituent of many rock types. It is clear with a pearly luster on cleavage faces, often having a sparkly look in rocks.
Several polytypes are known (see below).

Crystallography of Muscovite

Crystal System:Monoclinic
Class (H-M):2/m - Prismatic
Space Group:B2/b (B1 1 2/b) [C2/c] {C1 2/c 1}
Cell Parameters:a = 5.199Å, b = 9.027Å, c = 20.106Å

Morphology:Crystals uncommon, tabular {001} with rhombic to hexagonal outlines, often bound by {221}, {111} and {010} (hkl refer to -2M1 polytype). Less common as prismatic, parallel to [001], with a crude hexagonal cross section. Most typically found as "books" and as flaky grains in various rocks. Sometimes in plumose aggregates.
Twinning:Mica law twins common [310] forming six pointed stars, less common with the composition plane perpendicular to {001} (hkl refer to -2M1 polytype).

About Crystal Atlas

You may need to scroll this box using your mouse to view the full instructions.

The mindat.org Crystal Atlas allows you to view a selection of crystal drawings of real and idealised crystal forms for this mineral and, in certain cases, 3d rotating crystal objects. You need Java to see these. You can download Java for free - click here to download Java

The 3d models and java code are kindly provided by www.smorf.nl. You can control the movement of the models by holding down the left mouse-button over the 3d model and moving your mouse. Keyboard controls are:

: default positions
t/T: decrease/increase transparency x/X: next/previous texture
b/B: next/previous background w: toggle wireframe
s: toggle sticks m: toggle miller indices
k: toggle crystallographic axes =/-: zoom in/out
r: stop/start rotation 1/2/3


Note: You will not be able to switch between different crystal models using the Opera 8.5x web browser due to a bug in Opera - you need to use either Firefox or Internet Explorer 6/7 or Opera 9.
