Аннотация (краткое описание)

This paper presents data on the isotopic composition of fresh and mineral groundwater in the Mangystau region. The least studied component of the hydrologic cycle is groundwater involvement. Isotopes of natural origin are used as indicators to find out whether groundwater is replenished, its genesis, how it moves, whether it is at risk of pollution, and whether it is susceptible to changing climatic conditions. Waters of different genesis have specific isotopic signatures that leave a unique “footprint”. This is used to track the movement of water throughout the entire hydrologic cycle-evaporation, burial, infiltration, runoff, evapotranspiration, etc. This paper presents the results of a study of groundwater genesis using a comprehensive approach that would be relatively inexpensive and not require long observation cycles. In this case, to study the rates of water exchange and groundwater formation conditions in the Mangystau region used data on the chemical and isotopic composition of water (18O,2H), and the concentration of tritium (3H), obtained by sampling in September 2021 The sampled areas are located within the Mangystau-Ustyurt hydrogeological basin, which occupies the southwestern part of the vast Turan plate and is located south of the Caspian hydrogeological basin. Analysis of isotopic compositions (contents of deuterium, oxygen-18 and tritium) of water samples was performed at the Institute of Radiation Safety and Ecology (National Nuclear Center of the Republic of Kazakhstan) on a high-sensitivity laser spectrometer LGR 912-0008. VSMOW standards were used as reference standards, Measurement of radionuclide3H was carried out on liquid scintillation beta spectrometer TRI-CARB 2900TR. © 2022, National Academy of Sciences of the Republic of Kazakhstan.
