Session 3.2 ___ GNGTS 2023 Fig.2. Landscape microzonation map resulting from the morphological analysis and geocryological survey in September 2019 in the Khanovey study area. The position of boreholes and geophysical profiles used in this study are also shown. Silty clay deposits (brown dots) represent the major soil sediment texture type, except for the riverbank and for the northern sector, where abundant sand deposits are present (yellow dots). The active layer thickness values (direct estimations) are indicated by black triangles. Thermokarst phenomena, mainly located close to the railway embankments, is indicated by red dots; solifluction, inactive and active frost boils, gully erosion, and river terrace are also displayed.
