Resumen de Campos compresivos primarios vs perturbaciones de esfuerzos en la Cordillera Ibérica: una aproximación probabilística
Carlos Luis Liesa Carrera, José Luis Simón Gómez
A probabilistic approach to discriminate superimposed stress fields from a single stress field with multiple stress perturbations is applied to the central-eastern Iberian Chain. If two compression directions represent independent events, we assume that their probability of coexistence in a site should be the product of probabilities of occurrence of each one separately. Then, the regionalrecord of all possible combinations of compressional directions (percentage of sites where two ormore are recorded together) is compared to the theoretical probability. The results suggest that onlyone external stress field with multiple perturbations is not abble to explain the ensemble of compression directions inferred in the region. So, three different stress fields (Iberian, Betic, Pyrenean),each one including local and regional deviations, are proposed.
