Concepts
You should be able to give short answers to the following questions:
1.) What is the significance of Normal Faults in regional tectonics?
2.) What is the significance of "Younger-on-Older" stratigraphic relationships. (Draw a schematic cross-section that displays these relationships)
3.) What is a "Roll-over anticline"? How do they form?
4.) In what tectonic environments due systems of normal faults develop?
5.) What is meant by "Tectonic Denudation"?
6.) What is "Inversion Tectonics"?
7.) In what tectonic environments due systems of strike-slip faults develop?
8.) Explain how the geometry of Reidel Shears in association with a strike-slip fault system can be used to determine the sense of offset (dextral vs sinstral) and the orientation of the Principal Stress directions (s1 and s3). Check out figure 6.148 on p. 367.
9.) Strike-slip fault systems permit the simaltaneous development of local areas of crustal extension and local areas of crustal shortening within the same regional stress field. What fault geometries permit this? (Figures 6.153 and 6.154) What types of structures develop? (e.g., pull-aparts, pop-ups, folds thrust faults, normal faults etc.).
10.) Strike-slip duplexes are being recognized as important structural traps for migrating hydrocarbons. Discuss the development of the two main types of flower structures, with the aid of a schematic cross-section (see Figures 6.156, 6.157, and 6.158).
