Abstract

Unusually large cryoturbation structures (4–4.5 m amplitude), developed in channel gravels and overbank fine‐grained deposits of a river terrace on the NE Tibet Plateau, China, were formed by loadcasting as late Pleistocene‐age permafrost degraded. It is suggested that the oversaturation and liquefaction of the thawed sediments could have been achieved only if the amount of ice in the upper 4–4.5 m of terrace sediments had been very high. The structures, dated at around 26–20 ka by OSL, point to the presence of a massive icy layer existing within a permafrost body during the Last Permafrost Maximum.
