Correcciones geométricas en magnetotectónica: Filtrado de rotaciones aparentes debidas a pliegues
(Sociedad Geológica de España, 1996)The evaluation of apparent rotations asociated with different geological structures is an important task that has to be taken into account to correctly interprete paleomagnetic data. In this paper, the way to calculate ... -
Datos magnetotectónicos del Eoceno de la Cuenca de Jaca-Pamplona: resultados iniciales
(Sociedad Geológica de España, 1996)This paper presents the first magnetotectonic data of the central fringe of the Jaca-Pamplona Basin. These data have been obtained from 16 sites located in marls, tirbidites and limestones of Eocene age. In the central and ... -
Desarrollo simultáneo de pliegues, esquistosidad y cabalgamientos en el Eoceno inferior de Isaba (Valle del Roncal, Pirineo navarro)
(2006)Geometric and kinematic analysis of Pyrenean folds, cleavage and thrusts is carried out in several exceptional outcrops of the Eocene flysch at Isaba (Navarra, Spain). Distribution, orientation and cross-cut relationshi ... -
Estimación del acortamiento en áreas afectadas por rotaciones y su contestación con datos paleomagnéticos
(Sociedad Geológica de España, 1996)An extension of Cooper's (1983) method allows the calculation o f the bulk strain in rotated areas, If the maximum rotation of an area is known it is possible to determine the extreme values of bulk shortening for a specific ... -
Estructura de la Cuenca de Jaca en el sector occidental de las Sierras Exteriores Aragonesas
(Sociedad Geológica de España, 1996)In the western part of the Sierras Exteriores Aragonesas the southern Pyrenean front is not a southvergent large thrust, but an isoclinal detachment fold (Santo Domingo anticline), whose core is occuppied by the Upper ... -
Estudio preliminar de la fracturación a escala microestructural en las sierras marginales aragonesas
(Sociedad Geológica de España, 1990)Brittle microstructures in the «Sierras marginales aragonesas» have been analysed by means of the Right Dihedra, y-R diagrams and Etchecopar's methods. The existence of several compression directions can be interpreted as ... -
La transversal de Gavarnie-Guara. Estructura y edad de los mantos de Gavarnie, Guara-Gèdre y Guarga (Pirineo centro-occidental)
(2006)The structure of the eastern extreme of the Jaca Basin is defined by the Gavarnie, Guara-Gèdre and Guarga thrust sheets. The Guara-Gèdre thrust was active during mid Luttetian-earliest Chattian and the Gavarnie thrust, ... -
Rasgos estructurales de la Sierra de Salinas y zona de los Mallos (Sierras Exteriores, Prepirineo, provincias de Huesca y Zaragoza)
(Sociedad Geológica de España, 1990)The structure of Sierra de Salinas and the area of «los Mallos» (External Sierras, Southern Pyrenees) is owed to the thrusting (overtsep sequence) and simultaneous folding (flexure) of the whole structure. The setting and ... -
Las secuencias deposicionales del Eoceno medio y superior de las Sierras exteriores (Prepirineo meridional aragonés)
(Sociedad Geológica de España, 1990)The middle and upper Eocene marine sediments in the Sierras exteriores (Prepyrenees) are studied. Several depositional sequences are recognized: Calizas de Guara Formation (SD1, SD2 and SD3), Margas de Arguis Formation ... -
Zona de transferencia en el sector occidental del Pirineo Central, ejemplo de la falla de Oroz-Betelu-Unzué. Zona surpirenaica. Navarra
(2007)Based on structural, stratigraphic and gravimetric data, a regional scale N 020-040 E blind-fault, named the Oroz-Betelu- Unzue fault, extending from the western part of the Oroz-Betelu massif to the Sierra de Alaiz ...
