| dc.description.abstract | The Évora Massif is divided into two major tectonic units, in order to improve the general understanding of their internal complex structure: (1) the Évora High-grade Metamorphic Terrains and (2) the Montemor- o-Novo Shear Zone. Geological mapping based on stratigraphic, structural and metamorphism data of Neoproterozoic-Paleozoic rocks has shown great variations in style and Intensity of deformation and metamorphic processes on both tectonic units. A progressive deformation regime associated with slnistral transcurrent movements parallel to the orogen-strike is proposed to explain the overall structural pattern. Key words: Ossa-Morena Zone, Évora Massif, Évora High-grade Metamorphic Terrains, Montemor-o-Novo Shear Zone, Transcurrent movements | en_US |
| dc.description.abstract | El Macizo de Évora es subdividido en dos unidades tectónicas, con el objetivo de mejorar la Interpretación general de la su compleja estructura interna: (1) los Terrenos Metamórficos de Alto-grado de Évora y (2) la Zona de Cisalla de Montemor-o-Novo. Cartografía geológica basada en datos estratigráficos, estructurales y de metamorfismo en rocas del Neoproterozoico-Paleozólco han mostrado grandes variaciones en el estilo y intensidad de los procesos de deformación y metamorfismo en ambas unidades tectónicas. Es propuesto un regímen de deformación progressiva con movimientos transcurrientes izquierdos en paralelismo con la dirección del orógeno, para explicar la estructura general observada | en_US |
