Physical Geology 101
Metamorphic Rocks Study Guide


After the "Metamorphic Rocks" lecture and readings you should be able to answer and discuss the following questions.

What is a metamorphic rock?

What kinds of materials can be a Parent Rock?

What are the 3 parameters that can result in metamorphism?

What are the heat sources for metamorphism?

What is the lower temperature limit for metamorphism?

What is the ultimate upper temperature limit for metamorphism?

Why is this upper limit not the same for all rocks?

What are the two types of pressure and how do they operate?

What type of pressure will result in a foliated texture?

Explain the possible affects that hydrothermal fluids can have on rock?

Why do changes in the chemical composition and crystalline structure of minerals occur?

What is the difference between a foliated and a non-foliated texture?

In practice, how do you distinguish a slaty cleavage from a phyllitic texture from a schistosity from gneissic banding when looking at a foliated metamorphic rock?

What is required to distinguish one non-foliated metamorphic rock from another?

What is a porphyroblast?

What is Contact Metamorphism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

What is Regional Metamorphism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

What is Burial Metamorphism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

What is Cataclastic Metamorphism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

What is Shock Metamorphism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

What is Metasomatism and how does it operate? What are the conditions of temperature and pressure for this type of metamorphism?

Which two types of metamorphism are the most prevalent?
