Ch 11: Metamorphic Rocks: A Deeper Look

About This Chapter

Watch video lessons and learn about the different aspects of metamorphism as it relates to the study of the earth's surface features. These lessons are just a portion of our earth sciences learning materials.

Metamorphic Rocks: A Deeper Look - Chapter Summary and Learning Objectives

In earth sciences, 'metamorphism' refers to solid-stage changes in igneous and sedimentary rocks, changes that can take place due to heat (which could be caused by gravitational compression, friction, or radioactivity), pressure (including lithostatic pressure due to burial and the directed pressure caused by tectonic movement), and chemically active fluids (generally water). In this chapter, video instructors will guide you through the types of metamorphism and the classification of metamorphic rocks. You'll learn the vocabulary associated with the topic. At the end of this chapter, you should be able to:

  • Name and explain the factors that affect metamorphism
  • Define 'parent rock'
  • Tell the difference between foliated and nonfoliated rock
  • Differentiate between the different metamorphic products of shale
  • Explain the difference between contact and regional metamorphism

Metamorphism: Definition and Influencing FactorsDefine metamorphism. Describe how temperature, pressure (uniform and differential stress), fluids, time, and parent rock composition conditions influence metamorphism
Classification of Metamorphic Rocks: Texture and ParentExplain how metamorphic rocks are classified through texture (foliated vs nonfoliated) and parent rock. Describe the common metamorphic products of shale
Types of Metamorphism: Contact (Thermal) Metamorphism vs. Regional MetamorphismDifferentiate between contract (thermal) metamorphism and regional metamorphism
