The aim of this research was to obtain systematic data on stable isotopic compositions of C and O in carbonate pedofeatures in modern soils of the European part of Russia. The 7 key-sites were located in Lipetsk, Kursk, Voronezh, Rostov, Manych and Stavropol regions in Russia, and Samara in Ukraine. This transect represents the changes of climate (MAP and MAT) and vegetation (increasing of C4-plants portion under the domination of C3-vegetation). Isotopic composition of soft carbonates, corresponding to modern physiography, is usually slightly different from those of hard nodules, reflecting earlier environment. Carbonates with younger and older radiocarbon age were identified. Meanwhile, the carbonates with older radiocarbon age generally have similar stable isotopic compositions as the carbonates with younger 14 C age. Three bioclimatic types of environment were identified according to the stable isotopic compositions of carbonates : wet/cool, wet/warm, and dry/warm areas
