Using the geologic map, your structure sections, and your work in this chapter, write a succinct, complete description of each fault in the Bree Creek Quadrangle. Use complete sentences, but avoid them being long and rambling. Include the following information for each fault:

1. Type of fault (normal, reverse, strike-slip). (If you cannot determine the sense of movement with certainty, describe the possible senses of movement and the evidence for each.)

2. Attitude of the fault plane (including geographic variation).

3. Strike separation and dip separation (heave and throw) as the data allow (sometimes only a minimum amount of separation may be determined).

4. Age of movement as specifically as the evidence permits.
