Learning Objectives

After carefully reading this chapter, completing the exercises within it, and answering the questions at the end, you should be able to:

  • Summarize the factors that influence the nature of metamorphic rocks and explain why each one is important.
  • Recognize foliation and explain the mechanisms for its formation in metamorphic rocks.
  • Classify metamorphic rocks on the basis of their texture and mineral content, and explain the origins of these differences.
  • Describe the various settings in which metamorphic rocks are formed and the links between plate tectonics and metamorphism.
  • Describe the rock cycle and the types of processes that lead to the formation of igneous, sedimentary, and metamorphic rocks.
