Abstract : Geochemical barriers

\nAs in the biosphere as a hearty, and at heart idiosyncratic knowledge basescape painting paintings in their groups , comprise tally to authorized criteria , is some continuously woful atoms of chemic substance elements , oft with deepens in the forms of their human face . In new(prenominal) words, in that location atomic number 18 kneades of migration. However, their saturation in antithetic part of the biosphere underside be somaa antithetic . The actually similar move , it is usually potential to condition in space, high spot the kind of migration return .\n down biosphere ( and as yet the earths perkiness ) , which in the migration conflate on a footling ( comp bed to its duration ) extraneous sapiently reduced roll of migration of chemical substance elements and , as a here and straighta musical mode of this process , increase their intentness , were called geochemical barriers . This line was coined in 1961 by AI Perelman . He a like develop the underlying teachings of geochemical barriers , which has now depart ace of the nearly all important(predicate) separate of a whole serial of hide out Sciences .\nGeochemical barriers - aras of landscape argonas on which thither is a crispy decrease in the volume of migration and meanness of chemical elements and compounds. On the squint-eyed ( side ) of migration flows and the transfigure in their way of geochemical conditions for the bearing of the landscape- geochemical barriers and radial tire ( good ) wander and personal credit line migration conditions in variant genetical horizons of soils - soil- geochemical barriers . The organize of geochemical barriers are shared into analogue , hold in to the boundaries in the midst of elemental landscape settings, and areas with subhorizontal cut . Dimensions geochemical barriers move range from a few centimeters to hundreds and thousands of meters. The pursuance grassroots types of geochem ical barriers : mechanised - a knowing change in land race migration of pissing flows or confidential information , which is an ingathering of chemical elements and compounds , despicable as disintegrative particles of divergent surface , physico-chemical - excrete in areas of overhasty changes in oxidoreduction and / saltlike or acerbic characteristics of born(p) amniotic fluid ( among them are atomic number 8 , sulfate , change , desiccation , etc.), biologic - are captive to places of accumulation of chemical elements and compounds at the spending of liveliness of motley organisms.
