  • 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
  • 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.

  • Sedimentologic and stable isotopic studies in the Çal basin-fill provide new insights on the late Neogene–Quaternary climatic pattern in the eastern Mediterranean. An erosional unconformity separates the Pleistocene siliciclastic and calcrete
  • deposits above as a single sedimentary unit resting on top of floodplain fines and restricted to the basin center. The stable isotopic analysis of the palustrine carbonates and pedogenic calcretes displays a wide range of values and the lack of significant

  • , Pleistocene and Holocene. The sites were analysed in terms of colour, CaCO3, δ13 C and δ18 O isotopes, and micromorphology. The pedostratigraphy reflects more advanced soil developed after polycyclic weathering. The reddening results from polygenesis
  • (stable carbon isotopes and phytoliths) and mammalian fossil remains incorporated in an alluvial paleosol-sedimentary sequence. The AA. interpret the Late Pleistocene landscape of this area as a heterogeneous forest–grassland landscape with the forest
  • shrinking through time and the grass areas increasing. Both isotope and phytolith records demonstrate a contrasting difference between Pleistocene and recent vegetation dominated by xerophytic shrubs and succulents. This vegetation change could play
