El haz lineal filoniano granítico-adamellítico (riolítico), de dirección N120-130E asociado al batolito de los pedroches
(Universidade da Coruña, 1994) -
Estructura de la cuenca de As Pontes (A Coruña)
(Universidade da Coruña, 1994) -
Los problemas pendientes en la evolución morfológica del Sistema Central
(Universidade da Coruña, 1994)The Quaternary Landscape evolution in the Spanish Sistema Central range show a poor coupling with tectonic and climatic knowledge. Morphogenic activity shows more activity that could be explained in relation with accepted ... -
Interpretación de la estructura de la zona NE de la cuenca de Madrid mediante datos gravimétricos
(Universidade da Coruña, 1994)[Abstract] Modelling of five profiles in the NE area of Madrid Basin shows that low anomalies are related to both the thicker sediments infill of the Basin and the basement rocks like gneiss and granites. The highs are ... -
Los modelos genético-evolutivos del Sistema Central Español: implicaciones Morfotectónicas
(Universidade da Coruña, 1994)[Abstract] The characteristic morphostructure of the Spanish Central System corresponds to that of an ancient leveled massif, reactivated during the Tertiary Age by tectonic impulses related to the Alpine Orogeny; that is ... -
Extensión mesozoica y acortamiento alpino en el borde occidental de la Cuenca Vasco Cantábrica
(Universidade da Coruña, 1994)Geological cross-section through the western border of the Vasco-Cantabrian Basin show the existence ofthe extensional faults active during Permo-Mesozoic sedimentation, as well as the tectonic inversion of these faults ... -
Análisis tensorial de la deformación superpuesta en el límite oriental de la cuenca de Madrid
(Universidade da Coruña, 1994)An analysis of Neogene brittle deformation using fault populatíon analysis methods has been carried out between the SW border of the Iberian Range and Altomira Range. Two main paleostress fields have been established: 1) ... -
Reactivación alpina de pliegues y fallas del zócalo hercínico de la Cordillera Ibérica: Ejemplos de la Sierra de la Demanda y la Serranía de Cuenca
(Universidade da Coruña, 1994)[Abstract] The structure of the Variscan basement of the Iberian Chain conditioned the geometry and orientation ofstructures formed during the Alpine compression. In the Sierra de la Demanda, located in the north-western ... -
Los modelos tectónicos del Sistema Central Español
(Universidade da Coruña, 1994)The author presents the different tectonic models which have been proposed, in order to explain the origin ofthe Spanish Central Range. These tectonic models are divided in two main groups: the thick-skinned tectonics ... -
Neotectónica del borde oriental de la cuenca de Madrid
(Universidade da Coruña, 1994)[Abstract] An analysis ofthe neotectonic activity and the current stress state of the eastern border of Madrid Basin has been carried ont using structural-methods (fault population analysis), as well as seismological ... -
Introducción al estudio de la minería del hierro, en los Pirineos de Catalunya y de Andorra
(Universidade da Coruña, 1994)In the Catalan and in the Andorran Pyrenees, as in the ariegian one, there is an enormous conjunct ofold mining explotations, dedicated to the extraction and to the benefit of the iron minerals. This explotations had his ... -
Evolución tectonotermal asociada con extensión a escala cortical: el ejemplo hercínico del domo gneísico del Tormes (NO Salamanca, Macizo Ibérico)
(Universidade da Coruña, 1994)[Abstract] The tectonothermal Variscan evolution ofthe Tormes Gneiss Dome is controlled by a subhorizontal ductile shear zone of crustal scale and extensional characteristics, that induced a quick exhumation ofthe deep ... -
The Pangaean inheritance
(Universidade da Coruña, 1994)[Abstract] Very old palaeosurfaces have been identified and dated in several parts of the former Gondwana and Laurasia. In Australia the separation from Antarctica was complete by the end of the Eocene so that any surface ... -
Geoquímica del granito de dos micas de A Espenuca: origen y evolución
(Universidade da Coruña, 1994)[Abstract] The A Espenuca two-mica granite, situated in the northern sector ofthe Central Iberian Zone, was variably deformed by the Valdoviño Fault. Deformation intensity is observed to increase from W to E, also being ... -
Las Cuencas Terciarias gallegas en la terminación occidental de los relieves pirenaicos
(Universidade da Coruña, 1994)[Abstract] The structure shown by the Tertiary basins ofNW Spain is in agreement with a N-s shortening. These structures are specially well exposed in As Pontes and Meirama basins which belortg to a group of basins genetically ... -
Dimensionamiento y sostenimiento de minas subterráneas de pizarra
(Universidade da Coruña, 1994)[Abstract] We've studied the conditions about dimensions and support ofan underground mine of roofing slate in Galice, worked by rooms with continuous pillars. The rock mass was characterized by the empiric and analitic ... -
El relieve del Macizo Hespérico: génesis y cronología de los principales elementos morfológicos
(Universidade da Coruña, 1994)[Abstract] Erosion surfaces are the main geomorphological features ofthe Hesperian Massif. However, three other physiographic elements define the present state of the landscape. Such are big mountain blocks with polygonal ... -
Aprovechamiento racional de un afloramiento de granito
(Universidade da Coruña, 1994)[Abstract] This piece analizes the possibilities of mining exploitation in a little outcrop of rOSfl granite. The zone has been researched, recognizing the main structural discontinuities, and characterizing the rock mass ... -
Interpretación en 2 1/2D de la anomalí magnética del País Vasco: implicaciones geodinámicas
(Universidade da Coruña, 1994)The Basque magnetic anomaly (BMA) follows aNW-SE trend over the Basque country with intensities up to 250 nT and displays a paired negative part to the north with intensities down to -60 nT. A model of the magnetic ... -
Las paleoalteraciones sobre el zócalo hercínico ibérico: aproximación a una interpretación regional a partir de perfiles españoles
(Universidade da Coruña, 1994)The Hercynian basement of the Iberian Peninsula has undergone different stages of supergenic weathering which has given rise to a superposition of several «weathering mantles». Remnants ofan old weathering mantle, Mesozoic ...
