| Sumario: | For the first time radiocarbon dates with corresponding altimetry over present mean sea level are correlated for the Holocene of Argentina. Relative rates of continental uplift for 15 localities distributed over 3500 km of the Argentina coast are determined, and a model of coastal evolution is described. Maximum transgressive levels were reached between 4000 and 6500 yr BP. The relative uplift rates for the Holocene varied between 0.12 and 1.63 m/1000 years. The neotectonism along the Argentina coast is clearly evident as the minimum uplift rates are associated with sedimentary basins while maximum ones correspond to interbasin zones. -Authors |
