Central column: Top: View from Chateau de Quéribus, Pyrenees, France, looking north. What appears to be a folded layer is in fact a sequence of planar limestones that dip towards the south (towards you) and are transected by river valleys (photo by M. Schöpfer). Centre: Box fold within greywackes at Clogherhead, north of Dublin (photo by H.-P. Steyrer). Bottom: Plunging fold (the fold is plunging towards you) from Loughshinny, North Dublin, Ireland. The fold hinge exhibits a bend, stepping to the right (photo by M. Schöpfer).
Left and right column: Matlab generated 3D diagrams illustrating structure contours of various geologic structures (blue, transparent
surfaces) that intersect a simple topography (shown in shades from green to yellow). Topographic contours are shown as black curves,
structure contours are white and the outcrop pattern, which is projected at the base of each diagram, is plotted in red. For further details see article by M. Schöpfer in this issue.
