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

Arlegui, L.

Within the Sierra de Sigena there are joints with anomalous strikes. They show a vertical evolution becoming more similar to the regional fracture pattern as higher in the slope they appair. In the middle portion of the slope this set coexists with the regional-striking joints We interpret this joint distribution as a consequence of stress deflection caused by major faults in the basament, which shows possible attenuation upwardsspaAtribución-NoComercial-SinDerivadas 3.0 Españahttp://creativecommons.org/licenses/by-nc-nd/3.0/es/JointsStress fieldDeflectionHuescaEbro basinAlpine tectonicsVariación 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 perturbaciónVariation in the joint pattern along the neogene series of the Sierra de Sigena (Huesca): Possible relationships with the stress Field and its deflectionjournal articleopen access
