Periglacial landforms | Cryoturbation structures
Different types of cryoturbation (sedimentary deformations of cryogenic origin) are distinguished, interpreted in terms of mechanisms of formation and linked to their specific environmental conditions. Cryoturbations may originate from gravitational loading in the thawing soil (‘periglacial loading’...
