Aportaciones estructurales al conocimiento del sinclinal de Tamames: Dominio del Esquisto Grauváquico de la Zona Centro Ibérica (Macizo Ibérico)
(Sociedad Geológica de España, 2017)Un estudio estructural del sector oriental del sinclinal de Tamames, en la Zona Centro Ibérica (ZCI) del Macizo Ibérico, evidencia que la foliación tectónica asociada a los pliegues mayores es una crenulación que, por su ... -
The Central Iberian arc: implications for the Iberian Massif
(Universidad de Huelva, 2011)Variscan folds and magnetic anomalies of the Central Iberian Zone (Iberian Massif) delineate an orocline similar in size to the Ibero- Armorican arc but of opposite sense of curvature. Its core is occupied by the ... -
Coronitic metagabbros from the Sobrado Unit (Órdenes Complex, NW Iberian Massif). I: Geological setting and mineral assemblages
(Sociedad Geológica de España, 2002)HP-HT unit exposed in the core of the Sobrado tectonic window (Órdenes Complex, NW Iberian Massif) contains a lithological ensemble of arc affinity, affected by Lower Ordovician metamorphism and which reached highest ... -
Coronitic metagabbros from the Sobrado Unit (Órdenes Complex, NW Iberian Massif). II: Thermobarometry and P-T path
(Sociedad Geológica de España, 2002)Three types of corona textures developed in metagabbros of the Sobrado Unit. Detailed thermobarometry, carried out in groups II and III coronas, together with inferred P-T conditions for group I coronas, show that the ... -
Deformación extensional de las unidades alóctonas superiores de la parte oriental del Complejo de Ordenes (Galicia)
(Sociedad Geológica de España, 1991)A penetrative extensional tectonics, which includes the existence of three important detachments, has been identified in the Sobrado area, in the eastern margin of the Ordenes Complex. It is related to the extensional ... -
Descripción y resultados preliminares del plutón compuesto de San Xiao, Complejo de Cabo Ortegal (noroeste del Macizo Ibérico)
(Sociedad Geológica de España, 2002)The San Xiao composite pluton is a small body intruded in a metasedimentary formation of the Cabo Ortegal Complex upper units, the Cariño Gneisses. In spite of its size, it exhibits spectacular evidence of magma mingling ... -
Evidencias metamórficas y estructurales de extensión tardiorogénica hercinica: el ejemplo del Domo Gneisico del Tormes (NO Salamanca)
(Sociedad Geológica de España, 1994)The tectonothermal Variscan evolution of the Tormes Gneiss Dome is controlled by a subhorizontal ductile shear zone of crustal scale and extensional characteristics, that induced a quick exhumation of the deep parts of the ... -
Evolución metamórfica de los esquistos con Grt-St-Ky del antiforme de Arinteiro (Complejo de Órdenes, noroeste del Macizo Ibérico)
(Sociedad Geológica de España, 2002)The Órdenes Series in the Arinteiro anti form are generally Grt-St-Ky schists which exhibit a regional schistosity (SJ and a metamorphic peak mineral assemblage with Qtz-Pl-Ms-Bt-Grt-Ky-Rt-llm. Some garnets show a distinctive ... -
Nueva interpretación petrológica y tectónica de las anfibolitas pobres en calcio del antiforme de Arinteiro (NO del Macizo Ibérico). I: Descripción de las anfibolitas pobres en calcio y rocas asociadas
(Sociedad Geológica de España, 2002)Ca-poor amphibolites are characterized by unusual mineral assemblages, and they can be related to different tectonic settings. In this work we describe the amphibolites that outcrop in the Arinteiro massif. In this massif, ... -
Nueva interpretación petrológica y tectónica de las anfibolitas pobres en calcio del antiforme de Arinteiro (NO del Macizo Ibérico). II: Estructura e implicaciones para la génesis de anfibolitas pobres en calcio
(Sociedad Geológica de España, 2002)The Arinteiro massif has a complex structure which includes shear zones, recumbent folds, thrusts and upright folds. Ca-poor amphibolites occur associated with the shear zones, although there is some controversy about the ... -
Plegamiento recumbente en la Serra do Galiñeiro (Pontevedra, NO España)
(2006)Three main deformation phases (D1, D2 and D3) have been identified in the Serra do Galiñeiro using macro and microstructural analysis. The geometric characterization of those showing macrostructural elements (D2 and D3), ... -
Sobre la estructura del Antiforme de El Cardoso y el Sinforme de Majaelrayo y su relación con la Falla de Berzosa
(Sociedad Geológica de España, 1988)The El Cardoso Antiform and the Majaelrayo Synform are structures which were generated during the third hercynian deformation phase (F) and are cross-cut by the Berzosa Fault, a normal accident with a dextral wrench ... -
Subduction and syn-collisional exhumation of a Paleozoic continental margin: an integrated study based on structures and P-T paths of the Basal Units in the Ordenes Complex (Galicia, Spain)
(Sociedad Geológica de España, 1996)According to their metamorphic evolution, the Basal Units of the Galician Allochthonous Complexes are thought to represent a part of the margin of the Paleozoic Gondwana, subducted at the onset of the Variscan Orogeny. ... -
Tectonic setting of the Monte Castelo Gabbro (Ordenes Complex, NW Iberian Massif)
(Sociedad Geológica de España, 2002)En el Complejo de Ordenes (NW del Macizo Ibérico) la unidad tectonoestratigráfica superior está constituida por una potente secuencia metasedimentaria (Serie de Ordenes), intruida por ortogneises y gabros. El Cabro de Monte ...
