1. On separate pieces of tracing paper construct a b-diagram and p-diagram for the folds in Figure G-17 (Appendix G). Determine the trend and plunge of the fold axis.

2. Construct a profile view as shown in Fig. 7.6, and draw surface axial traces on the plan view. Determine the strike of the axial plane.

3. Draw a simple equal-area diagram, such as those in Fig. 7.7, showing the orientation of these folds.

4. Succinctly but completely describe these folds. Include the attitude of the fold axis, attitude of the axial plane, interlimb angle, symmetry, and fold class.
