• Resumen

  • Fault-propagation folds are important contractional structures developed in upper crustalconditions. Here we analyze a fault-propagation fold, made up of Carboniferous limestones, sited inthe Cantabrian fold and thrust belt, NW Iberian Peninsula. The technique employed consists ofdetailed structural analysis integrated with cross-section restoration. Such approach allowed us to validatethe geological interpretation and to decipher the deformation architecture using an inverse modelbased on strain markers. The results are illustrated overlapping contour maps and diagrams on top ofthe deformed, present-day cross section.
