• Resumen

  • Folds, reverse faults and thrusts in the South Portuguese Zone (SW Iberia) have been classically related with the progressive deformation of the Variscan thrust -fold belt. All structures verge toward South and Southwest. The style of folds in multilayers is analysed in this work. Ductile, brittle-ductile and brittle shear zones cut across the tight folds wisch exibit a WNW-ESE trend. The dip of axial surfaces varies from moderately inclined to upright. Detailed research in the Valverde del Camino anticlinal has revealed the existence of dome-basin patterns of folds related with the thrusts. The regional structures such as the Puebla de Guzmán and Valverde del Camino anticlinorium are associated with the geometry of thrusts
