The petrography and the structural geology of some parts of the ”Hercynian” orogene of western Galicia is discussed. The oldest rocks are metasediments and orthogneisses which have some relic-structures of an older orogeny. The ”Hercynian” migmatization gave rise to a large series of anatectic granite formations. Three ”Hercynian” phases of deformation, all with a WSW-ENE-directed stress-field, have been distinguished. Younger wrench-faults are originated by the same stress-field. Some fabric analyses show that the first two phases have a sub-vertical, NNW-SSE-striking schistosity, each with a horizontal B-axis, and that the third phase has a vertical N-S-striking cleavage with a vertical B’-axis. The migmatization took place after the first phase.
