dc.description.abstractExtensive outcrops of Tertiary sedimentary rocks appear between the Cordillera de los Andes and the Lago Buenos Aires in Patagonia. Oligocene marine sedimentary materials of the Centinela Formation crop out in some sectors of the areas crossed by the Jeinemeni and Zeballos rivers in the Province of Santa Cruz. They pass transitionally to the Rio Zeballos Group (Miocene) made up of continental sedimentary rocks. This paper describes the sedimentary Tertiary infill of the Rio Zeballos basin, constituted by three well-differentiated Formations: Jeinemeni, Boleadoras and Correntoso. We have studied the sedimentary profiles from the Lago Buenos Aires Meseta and Río Jeinemeni. These data allows to propose a new model of sedimentation consisting of alluvial fans associated with a deltaic complex and lakes affected by with repeated and periodic changes in the water levelen_US
