Description
Summary:In this paper, we consider the temporal dynamics features of the radioactive elements (Th, U) content in the core of a high-moor multilayer swamp peat deposit, typical for the forest zone of Western Siberia. The role of global, regional, and local factors in the accumulation of Th and U at different stages of bog formation has been determined. Significant direct and indirect (through the consequences of cryogenic processes) influence of the Holocene climate on the accumulation of these radioactive elements have been established. Significant losses of U in peat deposits of runoff flowing troughs were revealed. The Uconcentrations and EF (U) have been proposed as an indicator of the degree of the flow of bog paleoecotopes water regime.
