2.4.2b Variation in Dip Direction for a Thin Dyke (continued) 2.4.2  

This sequence shows the affect of a 200 m dyke. Other images are not shown as reduced to the pole images would only vary by rotation. The images show the variation in display formats between grey scale and psuedocolour look up tables, and colour contours, and the differences between folds at an inclination of -50° and -90°, together with first vertical derivative images at the pole.
