Arina Khatsenovich, Irina Vishnevskaya and Evgeny Mikheev preset results of their paleoisotopic research at the Institute of Archaeology and Ethnography SB RAS

They presented the first results on their study of Strontium isotopic composition: the first stage of ⁸⁷Sr/⁸⁶Sr ratio mapping in the Altai region and Mongolia and results of a study of faunal samples from Orkhon-1 and Moiltyn-am. ⁸⁷Sr/⁸⁶Sr ratios for bone samples, compared to results obtained on sediments from site profiles, indicate that some species did not permanently inhabit the Orkhon Valley , but migrated, presumably on a seasonal basis.
