    KEY CONCEPTS

    • Metamorphic minerals and rocks form when original parent rocks (protoliths) undergo changes in chemistry, texture, or composition.
    • Heat and pressure are the most important causes of metamorphism. Metamorphic fluids flowing through a rock may cause significant changes in some cases.
    • Different metamorphic textures characterized different kinds of metamorphic rocks.
    • Chemical reactions of many sorts occur during metamorphism.
    • Different parent-rock compositions produce different kinds of metamorphic rocks.
    • The composition of the parent rock determines the metamorphic minerals and rocks that may form.
