Определение происхождения лёссово-почвенных серий Русской равнины и палеогеографические закономерности их формирования

The fundamental scientific problem the project is aimed at solving is the characterization of the lithogenesis of the loess-soil series of the Russian Plain and the paleogeographic patterns of their formation. The study of the loess-soil series of the Russian Plain is necessary to solve many key issues of Quaternary geology and paleogeography, such as the problems of the genesis of loess deposits, their correlation with the Pleistocene chronostratigraphic schemes, the reconstruction of climate change and the prevailing directions of paleowinds, the evolution of soils and landscapes under the influence of global climate changes. The relevance of the project is due, on the one hand, to the obvious lack of data on the lithogenesis of the loess-soil series of the Russian Plain, and on the other hand, the lack of a clear scheme for the development of landscapes and climate dynamics in the region in the Pleistocene. A comparative lithological analysis of loess deposits in the south and center of the East European Plain will be carried out. As a result of the project, new data will be obtained on the mechanisms of formation of loess in the region and the evolution of sedimentation in the Pleistocene for a period of up to 1 million years, and reconstructions of changes in landscape and climatic conditions over this period will be carried out.
