14 C chronology and stable isotopes on Lymnaea viatrix shells in northwest Patagonia, Argentina. Do they express the Antarctic climatic reversal?
A multi-isotope environmental record comprising an upper section of the late Pleistocene and the lower and middle Holocene, including isotopic data on 30 samples of peat, marl, tufa, Lymnaea viatrix shells, and Hippidion sp. teeth, is described from a 15 m profile at Arroyo Leuto Caballo, Neuquén Pr...
