Stereonets for plotting fault orientation

Stereonetes are very useful for plotting the orientation of many faults in a single 2D plot . The stereonet represents a fault plane by a dot which is the intersection of a line normal to the fault plane and a lower hemisphere projection.

Figure 5.7: Example of stereonet for mapping faults caused by a normal faulting stress regime. The crosses indicate faults at an strike around 030$^{\circ }$ with dips around 60$^{\circ }$SE and 60$^{\circ }$NW
