Coeval interaction between magmas of contrasting composition (Late Carboniferous-Early Permian Santa Eulália-Monforte massif, Ossa-Morena Zone): field relationships and geochronological constraints
(Institut de Ciències de la Terra "Jaume Almera", 2017-12)The Santa Eulália-Monforte massif is a post-kinematic Late Carboniferous-Early Permian calc-alkaline composite massif (LC-EP) located in the Ossa-Morena Zone (OMZ, Portugal). This paper examines the field relationships ... -
Geochemistry of lower Paleozoic anorogenic basic rocks from the Evora Massif (Western Ossa-Morena Zone, Portugal)
(Sociedad Geológica de España, 2003)Undated basic rocks included in the Ossa-Morena westernmost domains (Alentejo region, Portugal) have been studied in an attempt to fill the lack of geochemical data for the Evora Massif. The selected outcrops, interpreted ... -
High temperature - Low pressure tectonites from the Boa Fé Fault Zone (Évora Massif, Ossa Morena Zone, Portugal): Evidences for transtensional tectonics
(Sociedad Geológica de España, 2003)Partial melting in the Évora Massif (Ossa-Morena Zone) occurred contemporaneously with non-coaxial deformation in a transcurrent regime. An example of this fact has been taken from studied partially melted biotite-sil ... -
Tonalites from the Hospitais Massif (Ossa-Morena Zone, SW Iberian Massif, Portugal) I: Geological setting and petrography
(Sociedad Geológica de España, 2004)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 ... -
Tonalites from the Hospitais massif (Ossa-Morena Zone, SW Iberian Massif, Portugal) II: Geochemistry and petrogenesis
(Sociedad Geológica de España, 2004)As described in the first part of this work (Moita et al., this volume), the Hospitais Massif belongs to a synorogenic Variscan magmatic association, intrusive in a gneissic-migmatitic complex of the Évora High- Grade ...
