On landslides age at slopes of water gaps in the celesta ranges (with reference to the Crimea)

Abstract

Downcutting of the rivers which break through celesta ranges provides favourable conditions for landslides (i.e. a certain ratio of the valley depth to clay and solid rock thickness) first in the upper part and later in the lower .part of the water gap. The conclusion has been confirmed by morphology and structure of landslips, and their correlation with river terraces and erosion surfaces. Because of the long existing unidirectional lateral shift of the river, landslips at left and right river slopes may be of different age.
