The paper maps bioavailable 87Sr/86Sr variation in 183 plant and soil samples across Cambodia. Bioavailable 87Sr/86Sr, as measured in plants, differs significantly between four major geological units. The data set will support future investigations of skeletal material from Cambodian archaeological sites. Baseline 87Sr/86Sr data should be applied judiciously to skeletal populations, and in concert with other lines of evidence, to identify potential geographical outliers rather than to ascribe specific locations from which individuals may have movedThey thank the Australian Research Council for supporting the research through the Discovery Grants programme (grantnumbers DP0984968 and DP110101997).application/pdfen-AU© 2020 University of OxfordCambodiaStrontium IsotopesBaseline MapPaleomobility2020-03-2410.1111/arcm.125572020-07-06
