Ecological Systems and Devices Annotation << Back Microstructures and geochemical parameters of man-made deposits of the middle of XVIII–beginning of XX Сhelyabinsk Razin A.D. Kazdym A.A. Household, commercial and industrial human activities contribute to the processes of transformation of rocks and soils, which are converted to man-made sediment layer. System of «man-biosphere» and «noosphere human development» implies a study of human impact on the environment and environmental change due to anthropogenic impact, that is part of modern ecological studies. The article describes the microstructures of man-made deposits of the middle of XVIII–beginning of XX Chelyabinsk and their geochemical parameters. Keywords: noosphere; technogenic deposits facies manmade; technological minerals; geochemistry; microstructure; heavy metals concentration; clarke. Contacts: E-mail: kazdym@mail.ru Pp. 35-42.
