Resumen:
The finding of continental and brackish to marine Pichaihue Limestones in the Agrio fold-and-thrust belt indicates that the first marine transgression derived from the Atlantic ocean had a much wider distribution in the central part of Neuquén, and probably covered a large part of the basin. This change from Pacific transgression to Atlantic ones that has been traditionally related to a regional tilting of the basin is clearly a consequence of the thrust loading of the Principal Cordillera during Late Cretaceous times.
