by B.B. Polynov, a complex of elementary landscapes from alluvial to super-aquatic located within the lithological homogeneous territories genetically tied by sources of dissolved and suspended matters.

zone of the sharply raised concentrations of these or those chemical elements as contrasted to their average contents in a given landscape (landscape clarke). B.b. arises, as a rule, in a zone of contact between elementary landscapes, biomocenosises (facies), distinguished by physical (e.g., filtration), chemical (distinction of oxidation-reduction, acid-alcalinous conditions) or biological (fissile activity of particular groups of micro-organisms) properties.

area on the surface of the Earth being distinguished by a content of chemical elements in its rocks, soils, waters, that influences on the composition and allocation of species of flora and fauna, and also on the health of people inhabiting this area.

a mass disturbance of development, growth and functioning of living organisms observed in a particular territory (biogeochemical province) and caused by a poor or exuberant content of particular elements in the environment (biotope).

cyclical processes of movement and transformation of chemical elements within the limits of biospheres occurring among its (bio) chorologic divisions: by biogeocenoses, landscapes, etc.
