Un modelo Gravimetrico 3-D para la corteza del NE de la península Ibérica
(Sociedad Geológica de España, 1996)Attention is focused on a three-dimensional model for the crustal structure of Catalonia (NE of the Iberian Peninsula). We combine different methodologies normally used separately in exploration geophysics to obtain the ... -
Tectónica extensional en el borde occidental de la Cuenca VascoCantábrica (Cordillera Cantábrica, NO de España)
(Sociedad Geológica de España, 1996)A geological cross-section in the western border of the Vasco-Cantabrian Basin show extensional faults active during Permo-Mesozoic sedimentation , as well as the tectonic inversion of these faults during Alpine deformation. ... -
Zonación tectónica, primer estadio de la zonación sismotectónica del NE de la península Ibérica (Catalunya)
(Sociedad Geológica de España, 1996)In areas characterized by a moderate seismicity, it is necessary to regionalize the seismic hazard, introducing concepts such as seismotectonic domains more than active faults. A first step of seismotectonic zonation is ... -
Velocidades de transmisión de ondas P y S en rocas máficas y ultramáficas. Datos obtenidos experimental mente y calculados. Macizo de Sierra Alpujata. (Cordilleras Béticas)
(Sociedad Geológica de España, 1996)The seismic properties of upper mantle representative samples from the Ronda ultramafic body (Betic Cordillera, Spain) have been determined using laboratory direct measurements and calculations based on the lattice preferred ... -
Tectónica de cabalgamientos en la Faja Pirítica Ibérica (Zona Sur Portuguesa): el Antiforme de la Puebla de Guzmán, y la lámina de cabalgamiento de Sanlúcar de Guadiana
(Sociedad Geológica de España, 1996)The Sanlucar de Guadiana thrust sheet and the Puebla de Guzmán Antiform in the central Iberian Pyrite Belt are interpreted as alloctonous units displaced to the south, forming part of an imbricated thrust system dipping ... -
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. ... -
Sobre el origen de la falla de Viveiro y su evolución respecto al macizo hercinico (Prov. De Lugo)
(Sociedad Geológica de España, 1996)The Viveiro fault is a ductile normal fault of Hercynian age which separates two distinct lithological units metamorphic evolution and tectonic styles. The foot wall in the east forms the Lugo dome, made with diferent ... -
Sismicidad en el antepaís de las cordilleras Béticas orientales: determinación del tensor de esfuerzos actual
(Sociedad Geológica de España, 1996)The seismicity in the Castilian foreland of the Betic Cordilleras is in accordance with an intraplate compressive stress-field that is characterized by the coexistence of two stress tensors: SHmax N140°-160°E (regional ... -
Períodos de recurrencia de paleoterremotos en sedimentos varvados lacustres del Mioceno superior. Cuenca de Híjar (Albacete)
(Sociedad Geológica de España, 1996)Paleoseismic imprimt in lacustrine varved sediments (Upper Miocene) has been made in the Hijar Basin (External Prebetic, Albacete). Mixed layers related to seismic activity have been observed in the varved sediments. These ... -
Origen de las brechas de la base del Jurásico en Morata de Jalón (Zaragoza)
(Sociedad Geológica de España, 1996)A sedimentary breccia is found in the lower Liassic (Hettangian?) in wide areas of the Iberian Chain (NE Spain). This breccia was originated during a tectonic extension at the onset of the Jurassic by a number of procceses, ... -
Red GPS para medidas geodinámicas en el Pirineo (ResPyr)
(Sociedad Geológica de España, 1996)A second geodynamical network has been set up in the Central and Eastern Pyrenees to quantify tectonic horizontal movements. The network is localized on the two sides of the Pyrenees and is composed by 20 points in the ... -
Preliminary results on 3He/4He isotopic ratios in terrestrial fluids from Iberian peninsula: seismoctectonic and neotectonic implications
(Sociedad Geológica de España, 1996)La sistemática de isotópos de helio está siendo aplicada en la península Ibérica con el fin de obtener información adiccional sobre las características neotectónicas y sismotectónicas del área de estudio. Resultados ... -
Neotectónica en el antepaís castellano de las cordilleras Béticas orientales
(Sociedad Geológica de España, 1996)The major morphotectonic features in the foreland of the Eastern Betics can be explained within the frame of the weak compressive stress field originated in the Prebetic fold and thrust belt. This NW directed compression ... -
Modelos tectono-sedimentarios de cuencas extensivas: serhigraben, graben de compensación y sinclinal sobre rampa (margen pasivo del Golfo de León, SE de Francia)
(Sociedad Geológica de España, 1996)Three tectono-sedimentary models are proposed for extensiona/basins in the Guif of Lion passive margin: (1) haif-graben associated to a listric fault, (2) compensation graben associated to a two-segments planar fault and ... -
Modelos gravimétrico y estructural del Sistema Central
(Sociedad Geológica de España, 1996)A gravity modelling of the Spanish Central System Crust has been carried out along two profiles. In order to constrain gravity modelling results Profile I runs along the Toledo-Salamanca seismic profile. Profile II trends ... -
Modelización numérica de la evolución geodinámica del surco de Valencia
(Sociedad Geológica de España, 1996)A numerical kinematic model of extension has been used to study the geodynamic evolution of the Valencia Trough. The model allows for depth-dependent lithospheric extension and lateral accommodation of extension. The best ... -
Modelización de la estructura litosférica del margen Sur Chileno a partir de datos gravimétricos y sísmicos
(Sociedad Geológica de España, 1996)The Chilean convergent margin south of the strait of Magellan represents an excellent opportunity to study a style of subduction where most of the parameters controlling this process remain approximately constant except ... -
Modelización gravimétrica en el SW de la Península Ibérica
Sánchez Jiménez, N.; Bergamín, J. F.; Fernández Rodríguez, Carlos
; Castro Dorado, Antonio (Sociedad Geológica de España, 1996)
A gravity research has been carried out in the southwestern part of the Iberian Massif to study the contact between the Ossa-Morena (OMZ) and Southportuguese zones (SPZ). The Bouguer anomaly map shows a relative gravity ... -
Modelos analógicos de la formación de lacolitos
(Sociedad Geológica de España, 1996)Dynamically scaled analogue models oflaccolithiç intrusions have been made. Experiments consisted of the injection of a Newtonian fluid (low-viscosity silicone putty) into a sandpack, with or without an interbedded ductile ... -
