Generating a directed structure in rocks is quite simple in principal,
you just have to non-unifomly scale the patterns you use for the surface
structure. Of course getting this 'look right' is not so easy. And
more complicated things like actual folding (i.e. a change of the
direction of the rock layers) is more difficult.
