Aproximación a la peligrosidad sísmica en la ciudad de Teruel asociada a la falla de Concud (NE España)
(Sociedad Geológica de España, 2014)This paper presents the results ofa probabilistic seismic hazard analysis at Teruel city from seismological and geological information. The characteristic earthquake of the Concud fault (M ~ 6.8; recurrence period = 7.3 ... -
Caracterización paleosísmica preliminar de la falla de Concud (fosa del Jiloca, Teruel)
(Sociedad Geológica de España, 2005)The Concud fault is a 13-km long fault located at the eastern boundary of the Jiloca graben (Teruel, Spain) that has been active during most of Late Pliocene and Quaternary times. Offsets measured in some dated stratigraphic ... -
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 ... -
El campo de esfuerzos compresivo neógeno en el NE de la Península Ibérica
(Sociedad Geológica de España, 1996)The Neogene stress field in the northeastern Iberian Peninsula is reconstructed from the analysis of brittle mesostructures (stylolytes, tension gashes, fault populations and joints). Compression directions obtained show ... -
Las bifurcaciones en diaclasas secundarias: geometría tridimensional (ejemplos de la Cuenca del Ebro)
(Sociedad Geológica de España, 1997)Forking is the process of fracture bifurcation ¡rito two or more diverging fracture planes. It occurs when a fracture reaches a critical velocity concomitant with its approach to a previous discontinuity. The literature ... -
Las diaclàsas E-W y NW-SE fen el sector central de la Cuenca del Ebro. Relation con el campo de esfuerzos Neógeno
(Sociedad Geológica de España, 1997)Thire are three regional joint sets in the central Ebro, basin. The southern part is. dominated by a primary N-S striking joint set and a secondary E-W set. In the nortnern part, the primary joint set strikes NW-SE Detailed ... -
Observaciones sobre las fracturas de las diaclasas plumosas
(Sociedad Geológica de España, 1991)Many joint surfaces show en échelon arrays of microfractures (F-joints) along one or both fringes of hackle marks. Our field observations indícate that, where both sets are present, they are stepped in oposite senses. So ... -
Variación del patrón de diaclasas a lo largo de la serie neógena de la Sierra de Sigena (Huesca): Posible relación con el campo de esfuerzos y su perturbación
(Sociedad Geológica de España, 1992)Neotectonic joints in the Ebro basin strike uniformly NNW-SSE, perpendicular or nearperpendicular to the direction of <33 in the moment it developed. Within the Sierra de Sigena there are joints with anomalous strikes. ...
