Fig. 9.18.
Structure contour map, cross section, and SCAT plots for a normal fault whose drag flattens
the regional dip. Fault strike is parallel to regional strike.
L:
regional strike;
T:
regional down-dip direc-
tion;
T':
regional up-dip direction;
CP:
crestal plane;

trough plane. (After Bengtson 1981a)
Fig. 9.19.
Structure contour map, cross section, and SCAT plots for a normal fault striking oblique to
regional dip with drag that steepens the regional dip.
