Mica minerals are really important, they make up 5% of the Earth’s crust. They occur in many different rock types. Muscovite is a common mineral in felsic igneous rocks (mostly plutonic). It could also be an alteration product of other silicates, mostly feldspars (in this case it is usually called sericite).
