Cryogenic Deformations in the Late Cenozoic Deposits of the Tunka Depression in the Baikal Rift Zone

摘要

Sections of the late Cenozoic alluvial deposits, which were exposed in the slope faces of fluvial terraces in the Tunka depression, are presented. Deformations in layered sediments and topsoil layers are characterized. The cryogenic mechanism of the development of the deformation structures in unconsolidated sediments is substantiated based on analysis of well-known publications and results of our own field studies.
