AbstractThe NE-SW «Garganta de las Pozas» ductile shear zone goes along the contact between one of the granodioritic sheets mapped and the «Refugio del Rey» anatectic complex. As well as the descriptive work, it has been determined the microfabric and the lattice preferred orientation (OCP) by EBSD in a cuarcitic sample, both studies confirm a lateral dextral movement in the shear zone. The dynamic recristalization in quartz has been produced by three different mechanism: subgrain rotation, grain boundaries migration and dauphine twin, which correspond to a deformation temperature of 575ºC.
