Conference Paper
Most passive margins present gravity-driven deformation due to a post-rift tilting to the ocean or to a rapid increase in the sedimentary loading on the outer shelf during their late stage of evolution. The result is the generation of a proximal extensional domain, with normal faults that transfer their displacement through a detachment level to a...

In the southern boundary of the Pyrenean Axial Zone several patches of Permo-Triassic unconformable sequences (cover) overlie Devonian formations (basement). This basement was deformed during the Variscan orogeny and later, during the Alpine orogeny, basement and cover deformed together. The unconformable cover presents several folds developed over...

The Pallaresa massif is a large E-W trending elongated antiformal variscan structure, located in the Axial zone of the central Pyrenees. The studied area is the transitional zone between Pallaresa massif and Aston and Hospitalet gneissic domes. Cambro-ordovician succession outcroping in this sector consists of an unfossiliferous, monotonous alterna...

... Sin embargo, sería factible considerar un reapretamiento de los pliegues variscos D2 durante la compresión Alpina, que podría llegar a ser suficiente como para asumir el acortamiento que los cabalgamientos alpinos registran hacia sectores más occidentales de la Zona Axial pirenaica. En este sentido, en la zona del Noguera Ribagorzana, situada al SO de la zona estudiada ( Fig. 1.5), el cabalgamiento alpino de Bono, con un acortamiento de 7 km en la ladera izquierda de ese valle, desaparece totalmente en la ladera derecha, donde su desplazamiento es acomodado por el reapretamiento de pliegues variscos (Gutiérrez-Medina et al., 2012) BIBLIOGRAFÍA ...
... During the Variscan orogeny, low-grade Paleozoic metasedimentary rocks were affected by progressive polyphasic deformation (Druguet [57], García-Sansegundo et al. [58], Casas et al. [59]), which mostly occurred during a compressional tectonic setting in which fold and thrust systems developed, giving rise to the crustal thickening of the Variscan cordillera in this region (Soula et al. [60]; Carreras and Capella [61], Gutierrez-Medina [62]; Clariana and García-Sansegundo [63]). Subsequently, in the last states of the variscan deformation, an extensional deformation event occurred. ...
