First direct dating of Late Pleistocene ice-wedges by AMS
We present the first direct dating by 14C-accelerator mass spectrometry of three Late Pleistocene syngenetic ice-wedges from the Seyaha cross-section. They are representative of permafrost with multistage ice-wedges from the North of Western Siberia. The most important result is the clear vertical a...
