Análisis cuantitativo de la fracturación tardihercínica en la Rama Aragonesa de la Cordillera Ibérica
(Sociedad Geológica de España, 1987)From the e/K' diagram, the late-hercynian deformational regime is deduced in the Iberian Range Eastern branch. An evolution from reverse strike-s/ip tectonics to radial extension related to dyke emplacement (Hiendelaencina ... -
Análisis de la geometría en profundidad de fracturas conductoras en zonas de baja permeabilidad mediante tomografía eléctrica (El Berrocal, Sistema Central Español)
(2007)The groundwater flow in zones of low permeability, as granites, is mainly associated with zones of fracture. For this reason the characterization of the fractures is fundamental, both in surface as in depth, and must integrate ... -
Análisis poblacional de fallas alpinas en el borde occidental de la Cuenca Vasco-Cantábrica (Cordillera Cantábrica, NO de España)
(Sociedad Geológica de España, 1996)Geological cross-section through the western border of the Basque-Cantabrian Basin shows the existence o f extensional faults active during Permo-Mesozoic sedimentation, as well as their tectonic inversion during Alpine ... -
Aplicación de técnicas estructurales y geoquímicas para la caracterización de fracturas conductoras en el batolito de La Cabrera (España central)
(Sociedad Geológica de España, 1996)Groundwater flow and solute transport within fractured crystalline rocks are mainly controlled by the geometry and the properties of each individual fracture. The hydrogeological characterization of a g ra n itic m assif ... -
Aplicación del método electromagnético de inducción ligera para el análisis de la permeabilidad en medios fracturados (granito de "El Berrocal", Sistema Central Español)
(2009)Fracture characterization in granites has been an important subject of study during these last years, by means of geological-structural cartography, hydrogeology and geochemical analysis. These works have been carried ... -
El Cabalgamiento de El Ibor: una falla cuaternaria a 20 km de la Central Nuclear de Almaraz
(Sociedad Geológica de España, 2021)Se describe un cabalgamiento cuaternario, que corta a una brecha sedimentaria que recubre la terraza de +5 m del río Ibor, en el extremo occidental de los Montes de Toledo. El sistema de cabalgamientos descrito ha ... -
Campos de paleoesfuerzos terciarios en el borde oriental de la cuenca del Tajo (España central)
(Sociedad Geológica de España, 1996)Three compressive pa/eostress fields, which have been active during the Tertiary, have been deduced from fault-slip data in the eastern border of the Tajo Basin. The first one («Iberian» paleostress field) had a N55E maximum ... -
Caracteristicas de los esfuerzos activos interplaca en la Península Ibérica
(Sociedad Geológica de España, 1996)Current active tectonic stress fields are deduced in intraplate areas of Iberian Peninsula with moderate to low seismic activity. Five areas are analyzed by means of individual focal mechanism data, populational analysis ... -
Crisis tectónicas cuaternarias en la cuenca de Madrid
(Sociedad Geológica de España, 1996)Quaternary sediment deformation structures of Madrid Basin have been analyzed. We get a high symmetry degree in deduced stress tensor trends, concluding that there are a regional stress field with NW-SE Shmax trend. Local ... -
Cuantificación del desplazamiento dextroso Alpino en la cordillera Ibérica a partir de datos gravimétricos
(Sociedad Geológica de España, 1996)Intraplate deformation in the eastern zone of the Iberian Peninsula is characterized by strike-slip faulting during Tertiary. Gradient pattern of Bouguer Anomaly Map of the Spanish Central SystemIberian Range linking zone ... -
Determinación de campos regionales de esfuerzo en el Prebético de Albacete
(Sociedad Geológica de España, 1996)A microstructural analysis has been carried out in the northernmost part of the External Zone in the Betic Cordilleras (Albacete province). Paleostress orientations have been calculated from 1.326 striated fault planes ... -
Determinación de los tensores de deformación y esfuerzo en calizas mediante el estudio comparado de poblaciones de fallas y del maclado mecánico de la calcita
(Sociedad Geológica de España, 1995)The strain tensor in limestones has been calculated using the strain-gauge technique (Croshong, 1972). This method is based in the analysis of the mechanical twinning in calcite. In the same outcrops, these-results have ... -
El cabalgamiento cenozoico de Boinás (Cordillera Cantábrica, España)
(2007)The opencast gold mine of Boinás, has allowed to outcrops the contact between the variscan basement and the Cenozoic sediments. It is observable that the contact is a post - Lower Oligocene thrust, with a N40ºE trend. ... -
Estado de esfuerzos actuales en el centro peninsular a partir del análisis conjunto de mecanismos focales de terremotos
(Sociedad Geológica de España, 1996)This study establishes current stress field in Central Iberia using earthquake focal mechanisms analysis. Inversion procedure is based on fault populational analysis. Two diferent orthogonal stress fields have been deduced. ... -
Estudio combinado del maclado de la calcita y de la fracturación para la determinación de paleo-tensores de deformación y esfuerzo
(Sociedad Geológica de España, 1996)The twinned-calcite strain-gauge technique allows determination of main axis strain magnitudes and orientations in limestones rocks midly deformed (Groshong, 1972), during Alpine orogeny in the Iberian Chain. This estudy ... -
Evolución de las deformaciones alpinas en el Sistema Central Español (S.C.E.)
(Sociedad Geológica de España, 1989)The Alpine Structure in the Spanish Central System results from three main regional deformation phases (1-Ibérica, 2-Guadarrama, 3-Torrelaguna) with differents shortening directions, 1-N45E, 2-N750E, 3-N160-200E. The ... -
Kink bands alpinos en rocas foliadas del basamento varisco del Sistema Central
(Sociedad Geológica de España, 2021)La asociación espacial y cinemática entre kink bands en rocas con foliación varisca y cabalgamientos alpinos en el basamento del Sistema Central, permiten deducir que los primeros tienen una edad cenozoica, y no varisca ... -
Mapa de esfuerzos de Europa a partir de Mecanismos Focales calculados desde el Tensor de Momento Sísmico
(2006)This work shows a new stress map for Europe obtained from the inversion of earthquakes focal mechanisms calculated with the centroid tensor method (Dzieownski et al., 1982). An amount of 1608 focal mechanisms have been ... -
Modelos de elementos finitos sobre los campos de paleoesfuerzos terciarios en el borde oriental de la cuenca del Tajo (España central)
(Sociedad Geológica de España, 1996)Two groups of finite element models have been carried out over Tertiary paleostress fields deduced from fault-slip data in the eastern part of the Tajo Basin. The first group corresponds to cover paleostress modelling, and ... -
Modelos gravimétricos para la corteza superior en el borde SE del Sistema Central Español
Babín, Rosa; Bergamín, J. F.; Fernández Rodríguez, Carlos
; González Casado, J. M.; Hernández Enrile, J. L.; Rivas, A.; Tejero López, Rosa; Vicente, Gerardo de (Sociedad Geológica de España, 1991)
A gravity research was carried out in the SE of the Spanish Centra/ System. The upper crust has been modelled in 2 1/2 D along three profiles. The gravity models suggest that the faults affecting both the Mesozoic-Cenozoic ...
