On the basis of the age determinations obtained they can judge the arrival of /sup 14/C and its distribution in sediments of the Caspian Sea and Dnepr-Bug liman. The age of the organic material being removed by rivers is 1500-2700 years for the Kura and Terek Rivers and 950-1200 years for the Dnepr and Southern Bug Rivers. The age of the carbonate of the Kura and Terek is in the range 13,000-14,000 years. The difference in the results of determining the age from the organic and carbonate fractions indicates the presence of a terrigenous component in the sediments. Slump phenomena and abrasion of the shores have a considerable effect on the distribution of radiocarbon in sediments. Despite the complexity of the process of sedimentogenesis, dating over the section makes it possible to calculate the sedimentation rates.
