Vocabulary Terms

You should be able to define the following terms.
 

displacement	Slip	Separation	Dextral "right-handed"
Sinstral "left-handed"	Strike-slip	Dip-slip	Normal-Slip
Thrust-slip	Reverse-Slip	Hanging wall	Foot wall
Oblique-slip	Stratigraphic Throw	Heave	Rotational-slip
Roll-over anticline	Drag folds	kinematic indicators	Tension gashes

Concepts

You should be able to give short answers to the following questions:

1.) What is the difference between "slip" and "separation"?

2.) You should be able to classify (i.e., name) faults according to slip or according to separation based on the available information. (Review Figures 6.43, 6.44, 6.45, 6.46, and 6.47, 6.48 and 6.50)

3) What are the three components of slip?

4.) How can tension gashes and drag folds be used to determine the sense of slip? Given a field sketch of a fault zone containing drag folds and tension gashes you should be able to draw a strain ellipse in the correct orientation and determine if the deformation was coaxial or non coaxial.

5.) Faults and Strain: Faults stretch the crust in one direction and shorten the crust in another. Normal-slip faults accomodate.....crustal-(blank),
Thrust- and reverse-slip faults accomodate......crustal-(blank),  Strike-slip faults accomodate.......(complete the sentence).

6.) Dynamic Fault Classification (Anderson's Theory) What assumptions did Anderson use to explain the relationship between the orientation of the principal stress directions and the dip on the fault plane?

7) You should be able to draw a schematic block diagram that shows the dip on conjugate fault planes and the direction of the principal stresses for normal-slip, thrust-slip, and strike-slip faults. (Anderson's Theory again).

8) Using the Coulomb criteria and Byerlee's Law you should be able to explain the conditions under which old faults will be reactivated and under which new faults will form. (This will be a review of  Mohr Circle analysis, see jointing).

9) How does the presence of anisotropies in the rock (e.g., foliation, cleavage etc.) affect the angle at which the fault plane will develop?

10) What is the problem with using Anderson's Theory to explain Reverse Faults? What does this imply in terms of how Reverse Faults may form?
