Oxygen isotopes and human mobility in Middle and Late Holocene hunter-gatherer groups from the eastern Pampa-Patagonia transition (Argentina)
This work seeks to explore human mobility in the lower course of the Colorado River (Argentina) during the Middle and Late Holocene (ca. 5900-250 years BP) through the analysis of stable oxygen isotopes (δ18O) of bone bioapatite. The δ18O values are interpreted and compared with those from North Pat...

| description | This work seeks to explore human mobility in the lower course of the Colorado River (Argentina) during the Middle and Late Holocene (ca. 5900-250 years BP) through the analysis of stable oxygen isotopes (δ18O) of bone bioapatite. The δ18O values are interpreted and compared with those from North Patagonia and Western Pampas to evaluate mobility at a regional scale. Forty-one adult individuals of both sexes from 12 archaeological sites were analyzed. δ18Oc values were transformed into drinking water (δ18Odw). The results were compared with the hydrological baseline generated for central-eastern North Patagonia and real rainfall data and predictive rainfall models. ẟ18Oc values indicate higher values in individuals corresponding to Middle Holocene (−0.7‰) compared with the Initial Late Holocene (−3.1‰) and Final Late Holocene (−2.3‰) and statistically significant differences between Middle Holocene and Late Holocene. Based on the δ18Odw values, 17.1% (7/41) correspond to hydrologic zones defined for central-eastern North Patagonia, and 48.8% to the real and predictive rainfall models. Although differences in δ18Odw values are observed between the Middle and Late Holocene, it is not yet possible to propose precise human mobility geographical directions in the study area. Nevertheless, during the Late Holocene, the δ18Oc values showed that individuals buried in the study area could have shared some water sources with those from Western Pampas and nearby sectors from Northeastern Patagonia, such as the lower course of the Negro River. |
