Postglacial transgressions in late paleozoic basins of Western Argentina: A record of glacioeustatic sea level rise

The areas marginal to main glaciated centers are appropriate sites to distinguish the record of glacioeustatic sea level fluctuations. The Late Paleozoic basins of western Argentina show a marginal position with respect to the glaciated areas of eastern South America (Brazil). In three of these basi...

description	The areas marginal to main glaciated centers are appropriate sites to distinguish the record of glacioeustatic sea level fluctuations. The Late Paleozoic basins of western Argentina show a marginal position with respect to the glaciated areas of eastern South America (Brazil). In three of these basins (Tarija, Calingasta-Uspallata and Central Patagonian) widespread glacial-marine diamictites and their gravity-reworked counterparts pass upward to open-marine fine clastics (mudstones, shales and scarce fine sandstones) with fossils of the Levipustula zone of Middle Carboniferous (Late Namurian-Westphalian) age.
