What is the angle between the two fractures? Along a vertical railway cutting, a bed has an apparent dip of 20° to 298°. If the bed strikes 067°, what is the true dip and dip direction?

Stereonets

1. Plot the orientations of the following stretching lineations, and determine their plunge and plunge direction:
a. pitches 06° N on 351 °/37° E b. pitches 79° W on 285°/62° N c. pitches 42° N on 358°/86°E Also, plot the poles to the above planes on
your stereonet.
2. Two fractures have the following orientations: 067°/38° SE, and 291 °/76° SW.
What is the plunge and plunge direction of  the intersection of the two fractures?
