Tonalites from the Hospitais Massif (Ossa-Morena Zone, SW Iberian Massif, Portugal) I: Geological setting and petrography

Abstract

El Macizo de Hospitais corresponde a un plutón elíptico de orientación ONO-ESE localizado en los domínios occidentales de la Zona de Ossa Morena, en Portugal. Este macizo, constituido por una asociación ígnea que incluye desde gabros hasta granitos y en la que son dominantes las tonalitas, está intruida en un complejo de gneises y migmatitas perteneciente a los Terrenos de Alto-grado Metamórfico de Évora. Las tonalitas muestran fabricas magmáticas asociadas a una foliación moderadamente desarrollada durante la cristalización y enfriamiento, paralelas a la foliación subvertical observada en los gneises y migmatitas del encajante. Las evidencias de campo y los estudios petrográficos permiten sugerir que la deformación de las tonalitas y rocas básicas asociadas que afloran cerca de Montemor-o-Novo, fue contemporánea con el progresivo cizallamiento Varisco observado en los gneises y migmatitas del encajante

The Hospitais Massif is an elliptical-shaped plutonic body, with a WNW-ESE long axis, located in the western Ossa-Morena Zone domains in Portugal. This massif, composed essentially of tonalites, is part of an igneous association, ranging from gabbros to granites, intrusive in a gneissic-migmatitic complex, as part of the Évora High-grade Metamorphic Terrains. The tonalites present magmatic fabrics associated with a moderately developed foliation, recording syntectonic crystallization and cooling, co-planar to steep foliations observed within the surrounding sheared gneisses and migmatites. From field and petrographic studies, it is possible to suggest that the deformation of the tonalites and associated basic rocks was synchronous with Variscan progressive shearing of the gneisses and migmatites envelope
