2.2.3b Variation in fault dip direction of high susceptibility footwall faults (continued)
2.2.3  


This sequence shows the affect of a fault which has a high susceptibility footwall block. Other orientations are not shown as reduced to pole images would simply vary by rotation. The images show the variation in display formats between grey scale and pseudocolour look up tables, and colour contours, and the differences between folds at magnetic inclinations of -50° and -90°, together with first vertical derivative images at the pole.
