SEISMIC DEFORMATIONS IN ALLUVIAL DEPOSITS OF LATE QUATERNARY IN THE NORTH OF WESTERN SIBERIA
The evidence of non-glacial development of the north of Western Siberia in the Quaternary was given. Numerous fragments of dolerites, impregnated in alluvial strata are the result not of glacial, but of ice-river spread. These fragments were brought from the right bank of the Yenisei with high water during spring ice drifting. We established the dominance of the processes of deep freezing of the Earth's upper horizons with the pseudomorphosis formation on polygonal-vein ice (PVI) - as the indicators of strong freezing, and the Sartan cracks with layers displacement up to 15 cm. These cracks were interpreted as seismites caused by 5-6 earthquake intensity. A series of <sup>14</sup>C-Dating within 10-12-th years made for bordering PVI cold hydromorphic paleosoils (with the fixed PVI spread time) proves the Sartan age of this complex.
