Calcareous loesslike loams in the center of the Russian plain and the soil cover evolution in the Late Pleistocene and Holocene

摘要

The genesis of calcareous loesslike loams in the Volga basin (Yaroslavl oblast) is considered. Statistical data treatment proves that the distribution of these rocks is controlled by the degree of natural drainage of the territory and the character of relief development in the Late Pleistocene and Holocene. It is shown that the origin of calcareous loesslike loams is intimately related to the evolution of the soil cover in periglacial regions of the Russian Plain.
