Resumen:
The interpretation of Acocella et al about (i) westward increase of strike-slip motion, (ii) strain patitioning, (iii) symmetry of the Central Andes, as well as (iv) the interpreted cause for the occurrence of magmatic centres behind the arc, from the Late Miocene onward, is largely speculative and contains many flaws. We demostrate all above, that successive phases of deformation from Middle Eocene ot Quaternary in the edge of the Puna-Eastern Cordillera, as well as the occurrence of arc/intraplate signatures in the magmatic centres of the Eastern Cordillera, result in complex geological framework which requires more detailed and intensive work in order to achieve sustainable interpretations.
