The Península Valdés region is situated in an intraplate position of theSouth American Plate, in the Patagonian foreland close to the ArgentineContinental shelf. This region has a complex geotectonic evolution that startedmore than 400 Ma and involves the conformation of Northern Patagonia as a part ofGondwana during the Paleozoic, the opening of the Atlantic Ocean during theMesozoic and the configuration of the Andean margin during the Cenozoic. Atdifferent scales, the interplay between climate, tectonic, sea-level, and volcanicprocesses, set the sedimentary routing system that had governed the final geologicrecords of the Península Valdés region and control the transfer of terrigenoussediments from source to sink. The stratigraphic record of the region was not onlyinfluenced by local factors. Processes developed far away from Península Valdés,both in the Southern Andes or in the continental shelf had influenced the lateCenozoic record of this region.
