Resumen:
The Lobería coastline is dominated by cliffs cut by the inlets of creeks and rivers. These cliffs are the best place to study the relationships between the Cenozoic stratigraphic units that compose the Pampean Plain. Within the inlets, the fluvial deposits are integered the remains of the Quaternary sea-level variations. The present erosion of the cliffs is constantly providing fossils that made this area one of the most important sections for the Quaternary period in South America. Present contribution is an updated description considering the present knowledge about ages, a reinterpretation of the paleo-environments based on diatom assemblages, and the tectonic significance of these sequences in relation to other areas.
