Ледниковый рельеф района Тикси (Западное побережье губы Буор-Хая, Северная Якутия)
Аннотация
Geomorphological research in Tiksi area, Northern Yakutia, revealed evidence for a former marine ice sheet centered on the East Siberian shelf. Fresh-looking U-shaped valleys, giant flutes, rock drumlins, tadpole rocks, scratched boulders, and impressive systems of glacio-tectonic ridges coupled with rock basins («hill-and-hole pairs») were uncovered in the area - all attesting to the past ice motion in landward (NE-SW) direction.
Beginning of lacustrine sedimentation in the rock basins was AMS-radiocarbon dated at 6450±110; 6870±80, and 8500±160 yr BP. Additional evidence for ice-marginal positions and ice-flow directions has been provided by «oriented lakes» of the Yana-Indigirka Lowland.
