Talc is formed from the metamorphism of magnesium-rich rocks, such as serpentine or dolomite, under high temperature and pressure conditions. These conditions cause the minerals in the rocks to recrystallize and form talc. The presence of water during this process also plays a significant role in the formation of talc.
