Internal Structure of the Évora Massif: The Évora High-grade Terrains and the Montemor-o-Novo Shear Zone (Ossa-Morena Zone, Portugal)
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...

| Resumo: | 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 |
