Chronostratigraphic correlations of cryogenic and glacigenic episodes in central andes with patagonia
Abstract The stratigraphy of cryogenic and glacigenic episodes recorded in Central Andes at latitude 33º south is compared with the magnetostratigraphy of five (I‐V) main Patagonian glaciations. Most of the Central Andes cold episodes are relatively dated. A much older event (≈ 2.3 × 10 6 years BP )...
