Abstract: Studying the origin and specific features of pressurized strong brine reservoirs in the Amu Darya basin is of significant importance at the present time. It helps to enhance insights into the geological and climatic history of the region, as well as contributes to the understanding the processes of sedimentary rock formation and its application in various fields of science and industry. The aim of this research is to study the geological and geochemical features of the pressurized strong brine reservoirs within the Amu Darya basin. This will help to understand how these properties affect the processes of hydrocarbon recovery. The study applied methods of geologic analysis and mapping of pressurized strong brine manifestations. In addition, chemical analysis of samples was used to determine the composition of the brines. The work produced a detailed description of the geological structure of the pressurized strong brine reservoirs, including their layered structure, texture and specific features of mineral distribution. Chemical analysis of the samples performed as part of the study helped to identify the key minerals that are present in the strong brines, such as gypsum, anhydrite and halite. In addition, the paper provides an analysis of the geological processes that resulted in formation of the brines. This allows a better understanding of the formation mechanisms and evolution of these sedimentary rocks during the history of the area. The data obtained make it possible to draw conclusions about the age and the formation conditions of the pressurized strong brine reservoirs in the area, as well as to assume possible changes in the geological and climatic history of the region. These results play an important role in improving our insights into the development of the geologic structure of Central Asia and may be useful for further research into the geology and climatology of the region.
