A young normal fault (
2
) cuts
and displaces an old normal
fault (
1
). An offset marker sur-
face is
shaded
. Displacement
on each fault is dip slip of a
constant amount. The displace-
ment of the offset geological
line is the slip on fault 2
Fig. 8.39.
Structure contour maps based
on the geometry of the struc-
ture in Fig. 8.38. Both maps
are at the same scale. Fault 2 is
through-going and displaces
fault 1 down dip 300 units to
the south.
