Figure 5.2.
Aerial photograph and sketch showing lineaments in an area underlain by gently
dipping sandstones.
Figure 5.2 shows several lineaments passing through an area in Central Australia under-
lain by sandstones dipping to the east at about 5 degrees. The major lineaments occur
along sheared zones with little or no displacement of the beds. The minor lineaments vis-
ible on the aerial photograph follow joints.
Linear arrangements of other features, e.g. vegetation boundaries, are usually found to
correlate with geological features.
