Abstract—
The Ryshkovo paleosol of the Mikulino Interglacial (MIS 5e), Late Moscow loess (MIS 6), and buried small erosional landforms were studied in the Taneyev Quarry of Kursk oblast, in the center of the East European Plain. Macro- and micromorphological and palynological analyses of the soil samples were carried out, and the OSL age and physicochemical properties were determined. The history of erosional landforms, soils, and landscapes was reconstructed on the basis of the facial analysis of the paleosol catena. It was concluded that the differentiation of the paleosol profile into the Ah–E–Bt horizons was developed during the Mikulino Interglacial, whereas the initial heterogeneity of the parent material had been formed earlier, during the Late Moscow (Saalian) Glaciation, under the impact of slope and cryogenic processes. The lithological matrix of the Ryshkovo paleosol did not remain unchanged due to the different history of interaction of eolian and slope (solifluction and colluvial) processes, initial pedogenesis, and interglacial soil formation.
期刊介绍：
Eurasian Soil Science publishes original research papers on global and regional studies discussing both theoretical and experimental problems of genesis, geography, physics, chemistry, biology, fertility, management, conservation, and remediation of soils. Special sections are devoted to current news in the life of the International and Russian soil science societies and to the history of soil sciences.
Since 2000, the journal Agricultural Chemistry, the English version of the journal of the Russian Academy of Sciences Agrokhimiya, has been merged into the journal Eurasian Soil Science and is no longer published as a separate title.
