The shear bands bear a stretching lineation underlined by alignments of fibrous sillimanite crystals at Dinard and St. Briac outcrops. These shear bands were analysed by means of the Right Dihedra method. They indicate a NNE-SSW stretching direction and a subvertical shortening direction. They are consistent with foliation and stretching lineation orientations. This study suggests that the St. Malo migmatite dome was affected by a post-orogenic extensional tectonic regime}, publisher = {Sociedad Geológica de España}, keywords = {Migmatites}, keywords = {Shear zone}, keywords = {Fault analysis}, keywords = {Cadomian orogeny}, keywords = {Armorican Massif}, title = {Deformación de cizalla en el domo migmatítico de St. Malo (Macizo Armoricano, oeste de Francia)}, title = {Shear strain in the St. Malo migmatite dome (N Brittany)}, author = {Román Berdiel, Teresa and Gapais, D. and Brun, J.
