Cryoturbations: A sediment structural analysis

Permafrost and Periglacial Processes, 1992, vol. 3, issue 4, 343-351

Abstract: Cryoturbations have always provoked discussions on their origin. However, the sedimentary structures which result from the deformations differ according to the mechanism involved. Diagnostic characterization by sedimentary structure is especially suited to distinguish between deformations caused by cryohydrostatic and cryostatic pressure on the one hand and by periglacial loading on the other. Depuis longtemps les cryoturbations provoquent des discussions sur leur origine. Cependant, les structures sédimentaires résultants des déformations peuvent donner une solution dans le cas où ces structures diffèrent selon le mécanisme de déformation. En effet, il existe une distinction claire entre les déformations dues aux pressions cryohydrostatiques et cryostatiques d'une part et les déformations produites par ‘loading’ d'autre part.
