ИСТИНА

The role of paleosols in the evolution of bio-geosphere cycles is based on the fact that more than 90% of all living organisms occur in soils. Biogeochemical record extends far beyond the existing definition of paleosol and includes, following Vernadski, all products influenced by terrestrial biota that constitute pedolithosphere (after Glazovskaya: terrestial sedimentary rocks, weathering crusts, etc., being paleosols, transformed in geo-cycles). Actually paleopedology is a science studying pedolithospheres of the past. With this approach we have continuous record in which newly discovered paleosols are enclosed like new cells in the periodic table.succession with an increased role of biological cycles in a geological cycle. Paleosols record a broad number of parameters (qualitative and increasing number of quantitative) and environmental links of former ecosystems, even if bio fossils are extinct. Co-evolution is especially obvious for revolutionary changes in weathering, like oxygenation of the atmosphere, radiation of higher plants and grasses. Paleosols comprise the major record in Quaternary terrestrial archives and are in the center of such multidisciplinary challenges like global climate change, carbon sequestration and cryobiosphere.
