Resumen
In this contribution we present a case study where valuable structural information on the extensional architecture of the Atuel depocentre (Neuquén basin) is obtained from kinematic analysis of small-scale normal faulting. The area was subsequently inverted during the Andean uplift, concealing most of the previous rift episode. We integrated the results of the kinematic analysis of minor faults with data from inferred major normal faults. We found a wide dispersion of the results obtained by the inversion method of fault-slip data, suggesting that the observed fault patterns reflect local deformations instead of responding to the regional stress field.
