Permian paleosols in relation to general issues of paleopedology

The study of Upper Permian paleosols in the eastern part of the Russian Plain enables us to consider general problems, like interrelation of pedogenic and lithogenic memory, the development of Pre-Quaternary loess-paleosol series, the use of red beds as a paleogeographic archive, the paleoenvironmental reconstructions based on the study of paleosols, pedostratigraphy, and the relationships between pedogenesis and sedimentation.
