| dc.description.abstract | In the Montemor-o-Novo high-grade metamorphic terraines of western Ossa-Morena Zone (Portugal), sheared migmatites display a wide variety of distinct mesoscopic structures. Relationships of leucosome-melanosome layering and rotated enclaves allowed determination in which direction the tectonic movement occurred. We proposed non-coaxial progressive deformation to explain how the fabric elements moved during D2 sinistrai shearing | en_US |
| dc.description.abstract | Las migmatitas cizalladas de los terrenos de alto grado metamòrfico de Montemor-o-Novo, que afloran en los dominios occidentales de la Zona de Ossa-Morena (Portugal), presentan distintas estructuras mesoscópicas. Las relaciones entre lo bandeado migmatítico (leucosoma-neosoma) y los enclaves rodados han permitido la determinación de la dirección del movimiento tectónico desarollado. Se propone la deformación progressiva no-coaxial para explicar el movimiento de los elementos de la fábrica durante la actuación del regimen de cizalla sinistrai | |
