Summary
This is an abstract from the "SAA 2021: General Sessions" session, at the 86th annual meeting of the Society for American Archaeology.
This paper presents the δ18O isotopes results based on a new southern Mendoza water sampling. Using GIS the δ18O isotope information from water sources is modeled in regional isoscapes. With this baseline we discuss human mobility, analyzing three archaeological cases. In total 92 water source samples from rivers, creeks, springs, snow, lagoons, and water holes, places among 3,200 and 400 m asl were analyzed. All of this data are discussed together with 158 human bone samples from hydroxyapatite from southern Mendoza archaeological sites between 34° and 37° SL. The results indicate a strong correspondence between δ18O water areas with δ18O human samples. Also, some of the results suggest changes in the mobility pattern through time.
