| Abstract | The geomorphologic, geologic and hydrologic studies were carried out on Putorana Plateau during 3 seasons: 1997, 1999, and 2000, including the Russian-German expedition in 1997. It was determined that the Putorana Plateau at the time of last glacial maximum (at the end of the Late Pleistocene) was represented by the ice caps and passive glaciers in the north of the plateau and by the outlet glaciers flowing along the valleys predominantly southward. The Plateau was not completely occupied by the glacial cover. Even the large tectonic cracks--lakes (Lama, Keta) at the present time, were not covered by glacial ice, which has been obtained from the data of analyses of lacustrine sediments and glacial complexes in the valleys of the lake tributaries. The outlet and valley glaciers backed the lakes and, therefore, their level increased up to 30-40 m. The time of deglaciation is determined grounding on radiocarbon age of organic remains in the dams, that backed the subglacial water bodies. This period was recognised as the boundary of Pleistocene and Holocene. The expansion of glaciation in the Holocene is also possible. |
