TWO-DIMENSIONAL REFOLD INTERFERENCE PATTERNS

When a rock undergoes two generations of folding, complex three-dimensional refolded structures result. If such a structure is then sectioned, two-dimensional interference patterns result. These patterns have been discussed before, but the incredible variety and complexities of these patterns can be shown only with a large number of diagrams. Using a computer simulation, various refolded structures have been sliced at every unique 30 degree combination of strike and dip (thirty sections per structure). The characteristics of the patterns observed are discussed and recurring recognizable patterns are identified.
