These materials are also affected by WNW-ESE Pyrenean folds, causing fold superposition, and syn-sedimentary extensional and strike-slip Cretaceous faults. These faults are characterized by thickness variations and roll-over folding. The Permian sediments are folded with WNW-ESE directions as a consequence of the buttressing against the reactivated Candanchú Fault, which represents the contact between the Carboniferous and the Permian units. The rocks situated in the proximities of this tectonic contact are strongly affected by the Pyrenean compression. The Carboniferous limestones present S-C’ fabric as well as other ductile microstructures, but also, to a lesser extent, fragile microstructures. Meanwhile, in the Permian sandstones the fragile structures are much more abundant than the ductile ones. The former are represented by a reverse fault conjugate system, rough cleavage, cataclasis and pressure-solution processes, and the later by ductile reorientation of phyllosilicates in the foliation planes. 000063767 521__ $$aGraduado en Geología 000063767 540__ $$aDerechos regulados por licencia Creative Commons 000063767 700__ $$aCasas Sainz, Antonio M.$$edir. 000063767 700__ $$aGil Imaz, Andrés$$edir. 000063767 7102_ $$aUniversidad de Zaragoza$$bCiencias de la Tierra$$cGeodinámica Interna 000063767 8560_ $$f681899@celes.unizar.es 000063767 8564_ $$s2423016$$uhttps://zaguan.unizar.es/record/63767/files/TAZ-TFG-2017-4821.pdf$$yMemoria (spa) 000063767 909CO $$ooai:zaguan.unizar.es:63767$$pdriver$$ptrabajos-fin-grado 000063767 950__ $$a 000063767 951__ $$adeposita:2017-12-21 000063767 980__ $$aTAZ$$bTFG$$cCIEN
