The heat and pressure of metamorphism transforms clay minerals into tiny grains of mica which enlarge as metamorphism progresses. Muscovite can occur as isolated grains in schist and gneiss or it can be abundant enough that the rocks are called mica schist or micaceous gneiss. Muscovite is not especially resistant to chemical weathering. It is quickly transformed into clay minerals.
