The morphotectonic processes that produce the current landscape happen by NE-strike transtensive-transpressive fundamental events later the Pleistocene. The progressive deformity of the Sierras Pampeanas towards the east is exhibited in the topographic elevations of the Chaco Plain (Dorsal Mujer Muerta and topographic highland of Otumpa, San Guillermo, El Recreo, and Mancilla). These positive reliefs obstruct and divert surface drainage drainage. At the beginning of the deformity, the Salinas Grandes depression was augment by the Sali River through the San Bernardo River. The advance of the neotectonic deformity generated the Alto de Mancilla that deflected the Sali River east to the Saladillo River, contents the Ambargasta lagoon accompanying water. Later, this drainage proposed towards the Mar Chiquita lagoon. The authoritative break-up of the Salí-Dulce river from Laguna Grande and Laguna de Ambargasta happen ca. 250 to 300 years ago. The transfer field between the Dulce and Salado waterways, north of the Mar Chiquita Lagoon, shows that the topographic survey resumes. This process implies that quickly, the Salado River could entirely capture the Dulce River with allure definitive break-up from the Mar Chiquita lagoon.
