The Chemical Composition of the Nitrogen Thermal Waters of the Khoja-Obi-Garm (Tajikistan) Balneoclimatic Resort

Resumo

This paper presents new data on the contents of macro- and microcomponents from low-mineral nitrogen thermal water located within the Khoja-Obi-Garm resort (Tajikistan). It was found that these thermal groundwaters contain high contents of F, Si, Li, Al, Rb, Sr, and Cs. Detailed study of the geological and hydrogeological settings of the resort, along with thermodynamic simulations allows us reveal the sources of chemical elements in these waters. A comparison of thermal groundwater from Khoja-Obi-Garm spa with the thermal waters of other regions of Eurasia was carried out; new data on the rare-earth elements and yttrium (REY) concentrations in the studied thermal water are presented as well.
