- Upper Permian paleosols (Salarevskian Formation) in the central part of the Russian Platform: Paleoecology and paleoenvironment Elena Yakimenko Svyatoslav Inozemtsev Sergey Naugolnykh Ciencias de la Tierra sediments paleosols paleoclimate soil horizons Upper Permian Ten to twelve pedosedimentary stages were identified within the Upper Permian red clayey sedimentsof the Sukhona and North Dvina drainage basins. Paleosols formed at these stages are generally similarin their profile arrangement and pedogenic features. The main pedogenic processes occurring in thearea during the Upper Tatarian appear to have been: (1) eluviation and gleying (reduction andmobilization of non-silicate-bound iron and removal of some fine clay) in the upper parts of soil profiles;(2) illuvial accumulation of iron, and some clay in the subsoil; (3) formation of secondary carbonates;and (4) generation of complex soil structure. These processes are interpreted to have taken place in asemiarid climate with sharp seasonal and long-term fluctuations in precipitation. Upper Tatarian plantcommunities at that time probably consisted mostly of shoreline hygrophytes and halophytes, andxerophyllous conifers living on relatively elevated areas. 2004 artículo científico 1026-8774 https://www.redalyc.org/articulo.oa?id=57221113 en http://www.redalyc.org/revista.oa?id=572 Revista Mexicana de Ciencias Geológicas application/pdf Universidad Nacional Autónoma de México Revista Mexicana de Ciencias Geológicas (México) Num.1 Vol.21
