• Resumen

  • Brittle microstructure in the «Sierras marginales aragonesas» have been ana/ysed by means of the Right Dihedra, y-R diagrams and Etchecopar's methods. The existence of several compression directions can be interpreted as the results ofa NINE regional compression and others (maint/y ENE and E-W) linked to compressive macrostructures striking N-S. Some of the extensive stress tensors obtained can be associated to extension in the footwal/ ofthe main thrust of the sierras
