El haz lineal filoniano granítico-adamellítico (riolítico), de dirección N120-130E asociado al batolito de los pedroches
(Universidade da Coruña, 1994) -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
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 ... -
El plutón de Linares (Jaén): cartografía, petrología y geoquímica
(Universidade da Coruña, 1994)[Abstract] Magma emplacement within the Linares granite, a part of the Los Pedroches Batholith, took place in the sequence: biotite granodiorite with microgranular enclaves, biotite monzogranites, and dike swarm complexo ... -
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 ... -
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 ... -
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 ... -

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 ...
