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.
