AB The Sanabria Lake plutons, located in the Central Iberian Zone of the Iberian Massif, intruded in a dextralstrike-slip fault bridge under transpressive conditions. The deformed zone underwent a strain partitioningprocess, so that large folded domains and narrow shear zones were developed coevally. The microstructuralstudy of the granitoids shows that the shear zones concentrate a variable degree of solid state deformationat high and medium temperatures, whereas the folded areas preserve microstructural evidences of magmaticand submagmatic flow at high temperatures, too. The most common fabric in these folded areas is definedby two sets of conjugate planes, composed by aligned crystals of plagioclase and biotite, which are bisectedby the flow foliation. These conjugate bands represent an incipient phase of the strain localization processthat involves strain weakening, migration of the late-magmatic melts and enhancement of the shear zones
