GLACIATION OFTHE WESTERN PART OF THE PUTORANA PLATEAU IN THE LATE PLEISTO CENE AND HOLOCENE

As a result of field glacio-geomorphologic studies and detailed analysis of aerial photos taken in the Imangda River valley (western part of the Putorana Plateau) four multi-aged moraine complexes were identified. Assuming as a basis that in the Late Pleistocene there were three stages of deglaciation in the north-west of Siberia (25–17, 15–13 and 11,5–10,4 thousand years ago) and that at its maximum stage the Late Pleistocene glaciation was mostly of mountain-valley type on the Putorana Plateau, we assumed that the first three moraine formations (the most ancient ones) correspond to these stages of the Late Pleistocene deglaciation. The fourth, younger moraine was formed during the Little Ice Age (the last millennium). According to our investigations and admitted assumption, in the Late Pleistocene and Holocene the glaciation of the territory was of cirque and mountain-valley type and developed only on the northern slopes. There was no continuous ice cover over the Putorana Plateau. However, isolated ice caps with outlet glaciers could exist in several parts of the Plateau.
