Description
Stereonets are used in many different branches of geology. Imagine a sphere with lines of latitude and longitude marked on it. Stereographic projection is used in geology, for example, to decipher the complexities of deformed rock by looking at the relationships between planes and linear structures; their bearings (trends) and angular relationships one with the other. The data is plotted on a stereonet as great circles and points (Wulff and Schmidt nets).
