Isotope composition of sulfur, oxygen and carbon in Black Sea sediments

Inversion of isotopic composition in the SO4(2-)-H2S system is shown to be universal in Neoeuxine sediments and an explanation of its occurrence is proposed. Change in isotopic composition of sulfate sulfur in Black Sea waters over last 10-15 thousand years is reconstructed. Periods of alteration between aerobic and anaerobic situations are identified, the beginning of entry of Mediterranean waters into the basin is dated, presence of authigenic carbonates in sediments of the sea is established and amounts are determined. Methane generation from carbon dioxide is shown to have been replaced by its generation from acetate in the paleo-Black Sea period.
