Geochemical barriers as forms of geosystems’ self-organization

Abstract

In article the attempt is done to estimate the functional role of geochemical barriers (GCB) in relation to properties and evolution of geochemical systems (GCS) becomes. The methodological base is fundamentals of Haken’ synergetics, the idea of self-organization of systems and nonequilibrium (non-linear) thermodynamics of I. Prigozhin and his school. From the author’s positions GCB are considered as the self-organized components of GCS in which an activization of physical and chemical processes is observed. It is leading to transformation of atomic molecular structures, chemical associations and separate chemical elements under the influence of the active medium (processes). They can be the defining phenomenon of emergence and evolution of geochemical systems. From the position of geoecology and geochemistry the estimation of permissible anthropogenic load on natural systems and its rationing are impossible without realizing the GCB role in migration and transformation of pollutants. The concept of geochemical barriers is the basis for actively applied in practice technologies for cleaning and protecting soils, underground and surface waters and the whole geological environment.
