A kinematic model for fault-related folds is proposed based on a field example from thePyrenees. A brief explanation of the model with remarks on its properties and why it was chosen tosimulate the natural structure is given together with a detailed structural analysis. The structure consistsof a meter-scale fold developed at the tip of a thrust fault with its backlimb dipping less than thefault surface and including a footwall fold. The suggested model presents an acceptable geometrical fittingto the studied structure and provides a reasonable evolutionary history for the fold. Graphs ofshortening vs. slip along the fault can be obtained using the model’s equations in which a possiblestructural path followed by the structure can be depicted.
