PALEOSOILS OF STEPPE ARCHAEOLOGICAL MONUMENTS AS INDICATORS NATURE DEVELOPMENT DURING HOLOCENE
Based on the studies of under-kurgan pedo-chrono-sequences the conceptual model of evolution of soils in the Lower Volga steppes within past 6000 years has been developed. The regularities on the centennial variability of morphological, chemical, microbial properties of paleosoils are elucidated. From the paleosoil data the dynamics of climate humidity in the region within the Eneolith, Bronze, Early Iron and Middle Age epochs is reconstructed. The crises and optima stages in the history of the natural development during the Holocene are revealed.
