Resumen:
The Late Paleozoic NPC is mostly syn-kinematic. Domain 1 would have shared with the YC a partially common deformational history, most likely at the final stages of YC deformation. It is interpreted that NPC records the transition from a Late Paleozoic compressive event towards a period of quiescence or perhaps extension. The event of compression is bracketed by the U-Pb ages of ca 300 Ma for the YC and of 282+-3 Ma for the BACG of the Navarrete area. The regional NE-SW compressional event, that we found recorded by Domain 1, has been considered by some authors as related with a frontal collision of Patagonia with SW Gondwana
