The assessment of territorial ecological stability of lithosphere components in typical tundra landscapes of the Yenisei Siberia

The study of the environmental resource of the lithosphere is one of the key details of general pat-tern of landscape environmental stability. The pur-pose of the work is studying several aspects of formation of lithosphere stability within the research area. The tasks were field traverses for studying the conditions within the research area, the analy-sis of existing data sources on the natural condition of lithosphere subsystems, qualitative assessment of the environmental resource (stability) of the stud-ied lithosphere components. The environmental components’ resistance to anthropogenic load was investigated in two levels: fields and desktop. Field works for studying the initial condition of environ-mental components within the research area were performed in environmental monitoring conditions at oil and gas license blocks. The desktop work was carried out with Miroshnikov’s et al. point scale method. The study reviews the results of field and office work studying some components of litho-sphere ecological stability: the analysis of bed rock composition for CaO content, metamorphism if any; genesis and lithological contents of covering de-posit; morphological and genetic relief features; engineering and geological features of rock com-plexes; soil cover; modern exodynamic processes. The obtained results will contribute to the general investigation fund of ecological potential assess-ment of typical tundra landscapes of the Yenisei Siberia.
