Technogenic Landscape-Geochemical Complexes of the Blyavinsky Copper-Pyrite Deposit in the Orenburg Region

Abstract

The purpose of research is to determine the landscape-geochemical features of the Blyavinsky copper-py- rite deposit's quarry, located in the Orenburg Region of the Southern Urals. The research objectives were: assessment of the concentration of chemical elements in natural and technogenic components (lithogenic base, quarry waters, and vegetation) of the technogeosystem of the Blyavinsky deposit; identification of key patterns of formation of geochemical facies – landscape-exposure tiering and paradynamic geofields. Materials and methods. Instrumental determination of chemical elements in samples of geochemical samples was performed by the method of atomic emission analysis. Results and discussion. The result of the analyzes was the determination of 44 chemical elements by atomic emission. The characteristics of geochemical features of 3 identified landscape-geochemical facies of technogenic origin are given: transeluvial positive on the western dump (III), transeluvial and locally accumulative positive on the western and southern dumps (IV) and transeluvial sharply negative in the quarry of the Blyavinsky deposit (VII). Conclusion. The obtained results allow us to interpret the main technogenic migration flows.
