Breakup and dispersion stages of Gondwana were ruled by crustal extension. In Patagonia, this regime was associated with the opening of extensional basins from the Jurassic onwards, a process that was interrupted by the Andean orogeny. New data generated from the hydrocarbon exploration and field studies allowed identifying Jurassic to Eocene contractional deformations, previously not registered in central Patagonia. We summarize here evidence for five compressional events intercalated with the extensional regime that affected central Patagonia from the Early Jurassic to the Paleogene. These events, denominated ?C1?, ?C2?, ?C3?, ?C4? and ?C5? acted diachronicronously producing tectonic inversion of the Jurassic-Cretaceous depocenters.
