Figure 9.9 is a geologicmap showing a fault.Onthe east side of the fault the beds all have an attitude of 335°, 40°E. West of the fault the rocks are poorly exposed, with only two outcrops, which have different attitudes.

1. Plot the attitude in the hanging wall on the equal-area net, and also plot the range of possible attitudes in the footwall that could result from rotation on this fault. Determine whether either of the two attitudes west of the fault could be the result of rotation on the fault.

2. If so, determine direction and amount of rotation.
