Reconstructing the anthropogenic aridization of landscapes in antiquity and in the Middle Ages from isotopic data

Ya.G. Ryskov, V.A. Demkin, V.I. Nikolayev, S.A. Oleinik, and P. Yakumin

The methods from geochemistry of stable isotopes, and spore-pollen and paleopedological data on climate humidification variation have been used to reveal three time intervals: the beginning of the 4 th millennium BC, and the 3–4 th and 8–14 th centuries AD when the indices of local climate changes showed oppositely directed tendencies, which suggests a contribution of the anthropogenic factor (pasture digression) to the modification of vegetation of the landscapes under investigation.

Keywords: isotope composition of carbon, isotope composition of oxygen, mammal bones, pasture digression, soil humus, soil carbonates, C3- and C4-plants.
