Geosphere, December 2007, v. 3, p. 527-549, doi: 10.1130/GES00093.1. Animation 3 - Generation of structural ribbons using geological contacts and structural domains. These ribbons are then interpolated into the subsurface. Two scenarios for the Top Pre-growth surface are shown that are constrained by the same structural ribbon. Scenario 1 is derived through a simple interpolation constrained by the structural ribbon. In scenario 2, the fold axis derived from outcrop data is projected into the subsurface and used to constrain the alternative surface. Using a priori knowledge, in this case that the fold axes are parallel structures at depth with little change in vertical offset, subsequent surfaces can be generated from their respective structural ribbons.
