Chronology of bathymetric variations of the Pueyrredón-Posadas-Salitroso lacustrine system during the Late Pleistocene to Early Holocene
The Pueyrredon-Posadas-Salitroso lacustrine system (PPS-LS) is located in the Andean Patagonia region of Argentina (47 220 2800S e 71 550 3400W) and represents a series of lakes formed as glaciers retreated during the late Pleistocene and early Holocene. These lakes began as proglacial lakes and lat...

| Sumario: | The Pueyrredon-Posadas-Salitroso lacustrine system (PPS-LS) is located in the Andean Patagonia region of Argentina (47 220 2800S e 71 550 3400W) and represents a series of lakes formed as glaciers retreated during the late Pleistocene and early Holocene. These lakes began as proglacial lakes and later evolved into periglacial lakes. This research presents the chronological evolution of the PPS-LS bathymetric variations based on the analysis of stratigraphic profiles surveyed at different locations and the dates obtained from lake sediments. Four paleogeographic sketches representing the chronological evolution of the PPS-LS between 23,580 BP and 5208 BP have been developed based on the integration of these data. |
