http://sites.und.edu/dexter.perkins/opticalmin/biotite.htm Web1 Biotite and muscovite belong to a family of platy minerals called “mica”. All have one strong cleavage and form sheets that you can pick apart with a knife or your fingernail. Micas strongly reflect light and appear shiny. Muscovite is also called “white mica” and biotite is sometimes called “brown mica” or “black mica”.
