10.1. Metamorphism and Metamorphic Rocks – Learning Outcomes

After reading this chapter of the textbook, learning the vocabulary, and working through the review questions, students should be able to:

  • Define the terms metamorphic rock and protolith.
  • List the principle factors driving metamorphism. Describe the role of each factor, and how variations in each factor influence metamorphism.
  • Describe the types of metamorphism and the environments where you find them. Give examples of types of metamorphic rocks found in each environment.
  • Describe the tectonic environments where you find each type of metamorphism, and features associated with metamorphism in these environments.
  • Define the term index mineral.
  • Describe how metamorphic grades vary with pressure and temperature.
  • Provide examples of silicate minerals that are only found in metamorphic rocks.
  • Provide examples of silicate minerals that are found both in metamorphic rocks and in igneous or sedimentary rocks.
  • Describe the metamorphic textures and how they form.
  • Describe how metamorphic textures vary with metamorphic grade.
  • Describe what metamorphic rocks are formed by each type of metamorphism when you start with different protolith rocks.
  • Define metamorphic facies.
  • Describe the metamorphic facies diagram. Explain the pressure and temperature conditions and metamorphic facies and grades rocks would pass through during:
    • (1) accretionary prism subduction in a subduction zone, and
    • (2) shallow contact metamorphism.

Learning outcomes not covered in the textbook chapter in detail, but we may discuss them in class (depending on your professor):

  • Provide examples of index minerals that are characteristic of low, medium, and high grade metamorphism.
  • Explain the difference between cleavage, schistosity, and banding.
