  • δ18 O-δ13 C may indicate subhumid conditions or significant diagenetic alteration. The δ13 C values of these carbonates, organic δ13 C data from calcretes and floral remains indicate that the landscapes were dominated by C3 forest plants.

  • 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.

  • In this study, the AA. investigated in detail the soil organic carbon (SOC) content and SOC stocks in soil profiles (mostly Andosols) along 2 altitudinal transects, situated on both the humid southern slopes and on the drier northern slopes
  • of the Kilimanjaro. These paleosol sequences are characterized by high soil organic carbon contents. SOC stocks per square meter exceed those of typical Andosols and Chernozems. As compared to the SOC storage in the surrounding savannah soils of the Maasai Steppe
  • , the buried black soils constitute a distinctive regional carbon storage hotspot.
