Topic 8   Metamorphism

Primary goals

• Explain how temperature, pressure, and water can affect metamorphic processes
• Explain how metamorphism occurs
• Know primary metamorphic rocks and their characteristics

Topics

8.1  How and why do rocks change?

• Explanation: What changes can happen to minerals during metamorphism?

• Explanation: How mineral texture can change during metamorphism? 

• Explanation: What do we mean when we say that minerals that have undergone metamorphism are more stable than the original minerals?  

• Explanation: What conditions in the Earth typically cause these changes?  

8.2  Contact metamorphism  

• Process: How does an intrusion cause metamorphism?

• Description: What would we see in the rocks at a contact metamorphism site?

• Description: Describe metamorphic grade

• Term: aureole

8.3  Regional metamorphism  

• Explanation: How can convergent boundaries result in metamorphism?

8.4  Metamorphic rocks  

• Terms: confining pressure; differential pressure

• Process: foliation

• Terms: slate; schist; gneiss; marble; quartzite

•  Course lecture notes from Prof. Nelson
