An archaeological strontium isoscape for the prehistoric Andes: Understanding population mobility through a geostatistical meta-analysis of archaeological 87Sr/86Sr values from humans, animals, and artifacts

Biogeographical studies of migration and mobility in archaeology and bioarchaeology rely on accurately characterizing local 87Sr/86Sr ranges, either through baseline studies or by statistically parsing archaeological results at a given site. However, when baseline materials are difficult to obtain or suspected to deviate from prehistoric isotopic catchments, archaeological data may provide an accurate characterization of local ranges. Through a...
