Paleocryolithopedogenesis and Evolution of Soddy-Podzolic Soils of the Taiga Zone in the Northeast of the East European Plain.

The results of pedogenetic studies conducted on soddy-podzolic soils in Gryazovets district of Vologda oblast are presented. The modern soils of the study area are represented by soddy-podzolic soils (Albic Retisols) developed from loamy parent rocks with paleocryogenic features. The role of paleocryolithogenesis in the formation and evolution of modern soddy-podzolic soils in the northeast of the East European Plain is discussed. The considered set of paleocryolithopedogenic processes and paleofeatures in modern zonal soddy-podzolic soils allows us to reconstruct the conditions of soil formation in the periglacial area of the Valdai glaciation. The results obtained have expanded the understanding of the influence of the Late Pleistocene cryogenesis and lithogenesis on the evolution of modern soddy-podzolic soils. It is discussed that paleocryolithogenic soil combinations resulting from the Late Pleistocene and Holocene cryolithogenesis and pedogenesis can be distinguished in the soil cover patterns in the northern part of the East European Plain.
