Resumen

We describe the main features of the Campillo shear zone, a band of intense deformation made of mylonitic to ultramylonitic rocks bearing a vertical foliation and subhorizontal stretching lineations. The shear zone is more than 2 km thick and extends along more than 100 km representing one of the largest tectonic structures of the Ossa-Morena Zone, comparable to the Badajoz-Córdoba Blastomylonitic Belt. Its longlasting activity and influence on the paleogeography and stratigraphy of a number of sedimentary sequences allow to consider the Campillo shear zone as an exceptional example of a continental-scale rectilinear high-angle fault zone within the Variscan orogen.
