НЕКОТОРЫЕ ОСОБЕННОСТИ ОРОГРАФИИ И ГИПСОМЕТРИИ ЗАПАДНОЙ СИБИРИ

Аннотация

About 6000 height level data of the West Siberian Plain (h _max and h _min in every cell of 20' x 30') were used in analysis. The northern part the plain has meridional strike of large landforms, its prevailing height level is 55-75 m; the southern part has diagonal strike and prevailing level 95-115 m. The average height of the plain is 96 m - 28 m less than that of the Russian Plain. Height histogram of West Siberia has 2 modes, while the Russian Plain has 4. On the whole relief of West Siberia is closer to graded profile, than that of the Russian Plain, though it is younger than the latter. Positive neotectonic movements being more active and differentiated in the Russian Plain may be the cause for such discrepancy.
