Abstract: The objective of the study was to analyze the main features in the geological structure of the evaporite formation in the Amu-Darya oil and gas basin in order to improve our understanding of the geological and environmental history of the region and to identify the potential of these deposits for various applications. Geological mapping, analysis of the mineral composition of the rocks, stratigraphic analysis, and geochemical studies were used in this study. The results showed that the evaporite formation in the Amu-Darya syncline consists mainly of the salt and sulfate rocks with a distinctive crystalline and fine-grained texture. This structure was formed under the impact of intensive water evaporation processes in the past, which is a key factor in understanding its genesis. Geological analysis has revealed the presence of geomorphological features such as salt lakes and salt marshes, which reflect the history of climatic and tectonic changes in the region. These features in the geological structure of the evaporite formation are important for a deeper understanding of its evolution over geological time and for determining its potential in various aspects, including environmental, economic, and scientific applications. Understanding the evaporite formation processes makes it possible to better assess the environmental aspects associated with these deposits and develop efficient strategies for managing the region's natural resources. Such a kind of research complements the general scientific knowledge of geologic development processes and can serve as a basis for future studies in the fields of geology, ecology, and geochemistry in this region.
