ABSTRACT SUMMARY The computer program Superposición has been developed in Pascal and compiled with Borland Delphi 2.0, to simulate the relationships between topography and geology. The program allows to create very simple geologies, formed by horizontal layers, or very complicated interference patterns, formed by three fold system, faults and a discordance. The interference patterns and their topographic expression are generated by using matrix methods. Superposición permits its employ as a didactic resource for teaching. The program can be used to resolve field observations as a part of a research project subject to the validity of the simple shear deformation model.

    ABSTRACT: Experiments on superposed folding were performed in a plane strain-pure shear rig using paraffin wax as an analogue for rocks. A series of pre-formed cylindrical folds were refolded with the compression direction acting parallel to the initial fold hinge direction, the intermediate axis perpendicular to the first fold axial plane and the extension direction parallel to the first fold axial plane and perpendicular to its axis (Type 1 interference geometry). Roundness, tightness and amplitude were varied to investigate the influence of first-fold geometry on the interference patterns. Experimental folding of an initially planar layer oriented parallel to the first-fold envelope provides a reference geometry for comparison. The results suggest that hinge roundness has less influence on the interference pattern than other factors. Close initial folds refold into Type 2 interference patterns, which become even more pronounced as the tightness increases; open folds produce Type 1 interference patterns. Folds with the same interlimb angle and the same roundness produce different interference patterns depending on relative amplitude: folds with relatively large amplitude are refolded into Type 2 patterns, whereas folds with small amplitude give clear dome and basin structures.In a second set of experiments, the compression direction also acted parallel to the first-fold hinge, but the orientations of the intermediate and extension axes were interchanged. The interference patterns obtained are very similar to those in Type 1 interference geometry, suggesting that the major factor in determining whether Type 1 or Type 2 interference patterns develop is the initial fold geometry and not the kinematics of the second deformation.

    ABSTRACT: 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° combination of strike and dip (thirty sections per structure). The characteristics of the patterns observed are discussed and recurring recognizable patterns are identified.
