Social differences in Neolithic/Bronze Age Myanmar: 87Sr/86Sr in skeletal remains from Oakaie 1 and Nyaung'gan

International audienceHere we begin to investigate prehistoric kinship and social differentiation in ancient Myanmar, through analyses of strontium isotopes in human tooth samples from excavated skeletal remains of 18 individuals from the archaeological sites of Oakaie 1 and Nyaung'gan, in Sagaing Division, central Myanmar. The archaeological deposits at these sites span the Late Neolithic and Early Bronze Age (approximately 12th to 8th c. BCE). These isotopic data are interpreted in association with bioarchaeological, material culture and stratigraphic data. These preliminary results suggest a differentiation in mean strontium signatures between the sites, which are
