Summary

  1. 1 Rotate the line 30–060 about an E–W horizontal axis, through an angle of 100° with a sense of rotation which is anticlockwise facing east. What is this line's new orientation?

  2. 2 Rotate the line 50–340 about axis 0–020. What is the minimum angle of rotation necessary to make the line horizontal?

  3. 3 A fault striking 030° and dipping 60W has permitted a rotational movement of the block on its eastern side. The beds on the western side strike 067° and dip 35N. What are the strike and dip of the beds on the eastern side after a 40° rotation with a sense which is clockwise looking down the plunge of the rotation axis?

  4. 4 A fold hinge plunges 58° towards 212° and another plunges 62° towards 110°. What is the angle between them?

  5. 5 A fault plane with orientation 130/30N displaces a bed with orientation 118/70N. Find the plunge and plunge direction of the cut-off line.

  6. 6 A fault plane (150/50W) has slickenside lineations on it which pitch at 60N. What are the plunge and plunge direction of these lineations?

  7. 7 An upright fold has limbs 180/60E and 031/80W Calculate the inter-limb angle? What is the apparent angle between the limbs visible on a vertical cross-section which trends 170°.

  8. 8 What is the apparent dip, on a vertical cross-section trending 040°, of beds with strike 020° and true dip 60E?
