Abstract
With the aim to reconstruct the Pleistocene soils in Azov Lowland (geological sections near the villages of Bezimenne and Melekinе Donetsk region), we carried out palaeopedological research. The Paleopedological method was used, which consisted with a detailed analysis of the morphological (color, structure, granulometric composition, humidity, composition, neoplasms, inclusion, transition between horizons, border) and micromorphological (skeleton, plasma, color, aggregation, porosity, organic and clay parts, mineral skeleton, tumors, microstructure) features. Paleopedological studies of Pleistocene soils have allowed to determine the types of these deposits and to follow the dynamics of changes in soil conditions: - warm-temperate with signs and close to subtropical, when formed reddish cinnamon (krb1), reddish brown (krb2), cinnamonish-brown (shb1), reddish cinnamon (shb2), dark-colour (meadow reddish cinnamon) merged (mrb2 + mrb1), reddish cinnamon, brownish, fused saline soils (mr3) Kryzhanivka, Shyrokyno and Martonosha soils, which are distinguished by reddish shades of coloring of the profiles, are the most ferruginous, clay, with a large number of nodules witch concentration of organo-iron-clay material; - moderately-warm transition to subtropical – red-brown saline (lbb2), dark-colour (brownish-cinnamonic) fused (lbb2 + lbb1) heavy loam Lubny soils, with are less clayed, ferruginous and formed in meadow-steppe and steppe conditions (brownish-gray with cinnamonish shades of coloring profiles,the presence of moleholes, complex microaggregation); - moderately variable – humid close to subtropical – cinnamon and cinnamonsaline (zvb1), reddish-cinnamon saline (zvb2), heavy loam Zavadivka soils, which are a transitional variant to temperate climates, although some of the features of the lower Pleistocene soil formation are retained (ferrugination, presence of segregated clusters organo-clay and clay materials, microortshteins); - moderately-warm equally humid – cinnamon-brown (kdb1), ordinary chernozems (kdb2), cinnamonish-gray saline (plb1), chernozem saline (plb2), brown steppe (plc), heavy and medium loam Kaydaky and Pryluky soils, characterized by the grayish shades of coloring of profiles, the presence of moleholes, carbonates, complex microaggregates, pores and are closest to modern soils; - moderately-warm subarid – cinnamonish-brown (vtb2) heavy loam Vytachiv soils formed under the influence of turf (the presence of crust, carbonate, complex microaggregates) and brown-liked (cinnamonish-brown color of the profile,spatial structure of clays) of soil formation processes and have no analogues in modern soil cover; - moderately-continental and more arid (dry) – chernozems saline (dfb2), brown saline (dfc), desert-steppe fulvous (dfc), medium loam Dofinivka soils, with clear features of xeromorphism (low profile power, its carbonate, lack of signs of organo-mineral materials) replacing.References
