Late Pleistocene-Holocene paleoenvironments in the middle basin of the Salado river, province of Buenos Aires, Argentina

The Salado river basin is the largest one in the Buenos Aires province, with an area near 170,000 km2. This work aims to perform a stratigraphic analysis of the middle sector of this basin to provide information on the paleoenvironmental evolution during the end of the Quaternary. Results indicate t...
