英文摘要	The “classic type” ice-cored frost mounds are widespread in the northern taiga of Western Siberia. Besides, morphologically different forms of permafrost-related hummocky terrain are developed, differentiating from the “classic” frost mounds by size and flat tops. Using core samples from the ten-meter deep boreholes, we have analyzed the total thickness of segregated ice and the contribution of ice inclusions to the total soil ice content, to determine the origin of such flat-topped frost mounds. A good correlation has been revealed between surface elevations and volumetric ice content of sediments composing the mounds, whose iciness is found to be higher than in the depressions between them. These facts indicate the local nature of ice segregation and therefore suggest that the investigated landforms were formed by the frost heave processes, rather than being remnant permafrost landforms. © Н.М.
