Drawing faults

Faults are commonly encountered during geology fieldwork and are frequently the subjects of sketches in the field. This chapter introduces simple field sketches using faults as an example. It considers how best to draw faults in the field and the important features of these structures to record. Two worked examples of field sketches are given and focus on the techniques employed to draw their geometries accurately. The rules introduced in Chapter 2 are revisited, as are the techniques of blocking-in, adding key features, and the importance of labels and scale. Both simple faults and complex fault zones are considered in the chapter. Common mistakes made in geological sketches are also described.
