In this process, as deeply buried fault zones are gradually brought to the surface over geological time, the reduction in temperature and confining pressure creates brittle phenomena, such as mesoscale fracturing and microscale cataclasis, which are further altered by fluid movement in the FGWZ.
La proliferacion de deslizamientos activos se asocian a la disposicion estructural (planos de fallas y altas pendientes de las laderas), que han definido extensas zonas de deformacion y cataclasis, favorecidos por las precipitaciones.
Close to the contact, the fabric in micaceous rocks typically shows the development of a new crenulation cleavage overprinting the generally planar foliation, and more quartz-rich rocks display moderate to strong cataclasis with undulose extinction and bent mica grains (Fig.
