Variations in 87Sr/86Sr ratios in contemporary snail samples obtained from the eastern Caucasus

详细

Variations of ⁸⁷Sr/⁸⁶Sr ratios in different natural objects make it possible to obtain new data having great importance for the identification of the possible place of origin and migration routes of ancient humans. The discussed data were obtained from contemporary snail samples inhabiting the landscapes of the eastern Caucasus, which is characterized by different parent rocks. It has been found that the ⁸⁷Sr/⁸⁶Sr ratios in samples originating from landscapes with rocks of the same type are generally the same, while those in samples originating from landscapes distinguished by the character of underlying rocks vary to a significant degree.
