Physical Geology 101
Structural Geology Study Guide


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

What is the difference between tectonics and Plate Tectonics?

What are the three forms of stress and how do they behave on earth materials?

In general, how do rocks behave when stress is applied to them?

Describe the difference between stress and strain?

Define ductile and brittle deformation and describe the difference between them.

Describe the structure or shape of each of the major fold forms.

For each of the major fold forms what is the stress that has been applied?

If an anticline is eroded flat, where will the youngest rocks and oldest rocks be located relative to the fold axis?

If a syncline is eroded flat, where will the youngest rocks and oldest rocks be located relative to the fold axis?

If a dome is eroded flat, where will the youngest rocks and oldest rocks be located relative to the fold center?

If a basin is eroded flat, where will the youngest rocks and oldest rocks be located relative to the fold center?

Describe the difference between a joint and a fault?

What two criteria are needed to classify a fault?

Draw a diagram showing the major features of a fault.

For each of the major fault forms, describe the relative motion, fault plane orientation, and stress that has been applied.

Describe the similarities and differences between a horst and a graben?

How does a graben differ from a half-graben?

What are the various symbols used on maps to define faults and fault features?

What are strike and dip?
