The significance of cryoturbation phenomena in environmental reconstruction
Abstract Cryoturbation results mainly from differential heave related to (1) drainage and thermal conditions and (2) frost susceptibility. Loadcasting and cryostatic pressures are restricted to wet soils such as pure silt or silty sand. The translocation of fine particles resulting from repeated fre...
