Abstract
The proposed procedure of identifying the stages of formation of mountain gorges is based on the use of the orotectonic method. This method makes it possible to reveal schemes of different-scale erosion-accumulative cycles in the gorge and adjacent valley of a large river. These schemes are compared with each other and successively correlated with local and regional stratigraphic schemes for dating the identified stages. The proposed complex of geological, geomorphological, and correlation studies can be used to analyze the history of formation of gorge river valleys in active orogens, such as the Caucasus and Tien Shan. It may also be helpful for paleoenvironmental reconstructions in archaeological research and geotechnical surveys.
