1. On the accompanying map, draw the fold axes and indicate whether they are synforms or antiforms.

2. What is the direction and dip of these axes?

3. The following measurements have been made on the cleavage:

Position 1: 101/86, 101/76, 103/70, 106/55, 277/86

Position 2: 114/30, 139/13, 253/17, 269/40, 274/56

Position 3: 278/46, 279/69, 278/78

Position 4: 098/73, 101/45, 102/21

a) Project the cleavage and fold axes on a stereographic net.

b) Describe the geometry of the cleavage.

4. Calculate the throw on the fault FF

5. Estimate the angle of the unconformity between layer H and the underlying beds that follow the contact SM

6. How were the beds below H oriented when H was first laid down?

7. Draw the geological structure employing geological cross-sections.

N.B. We have used a different format than you have seen before for describing planes. Instead of using the strike and dip of the plane we use the trend and dip of the line in the direction that the plane dips the greatest. e.g. we use 330/43 instead of 060/43 NW and 150/43 instead of 060/43S
