Abstract

The integration of palaeostress results obtained from the analysis of non-striated faults and joints affecting Plio-Pleistocene deposits near the Concud fault (southern Jiloca graben, eastern Spain) yields a multidirectional tension stress field (vertical s1, s2zs3) where the primary s3 trajectories trend ENE. The results also show strong deflections of stress trajectories, with many local s3 axes being either orthogonal or parallel to the trace of the Concud fault. The stress field persisted throughout the period of activity of the fault, i.e. Late Pliocene and Pleistocene. The agreement between the present results and the regional picture gives support to the stress inversion method and shows its usefulness in palaeostress analysis of young, poorly lithified rocks.
