“…These results indicate that the hydrochemical composition is likely mainly controlled by the dissolution of silicate minerals. Subsequently, the weathering of silicate minerals is estimated based on geothermal water with mineral phase equilibrium analysis [40,41]. The chemical activity plots of the Na2O-Al2O3-SiO2-H2O system and the K2O-Al2O3-SiO2-H2O system are shown in Figure 6.…”

“…The high pH and low salinity are typical for the N2-rich thermal waters but unusual for the majority of natural waters. The explanation for this is discussed in details in [1,3,6], but it should be briefly mentioned that this results from OHformed by the hydrolysis of aluminosilicate minerals and the absence of alkalinity neutralizing acids. The redox (Eh) predominantly ranges from -350 to -110 mV but there are two hot springs, 16-5 and 16-7, where Eh values are respectively 38 and 124 mV.…”

“…4c). We will not focus on the fluorine's sources and its accumulation mechanisms in details because it was considered previously [6,9]. But briefly mention that the high concentration of Fin the studied thermal waters are the result of aluminosilicate hydrolysis and relatively low Ca values.…”

“…В настоящей работе рассмотрены только азотные термальные воды, в газовом составе которых азот составляет 95-99 об. % [6]. В геологическом отношении выходы азотных терм сложены преимущественно гранитами юрского возраста, в меньшей степени позднепротерозойского эона, а также кембрий-ордовикскими гранитами (С-O) и каменноугольными и девонскими гранитоидами (С-D) [6].…”

“…1). Кроме этого, состав рассматриваемых терм характеризуется повышенными концентрациями SiO 2 (32-134 мг/л) и F -(2,8 до 15,6 мг/л) [6][7][8]. Оценить степень смешения термальных вод с грунтовыми водами или атмосферными осадками и более точно определить глубинную температуру можно с помощью нанесения фигуративных точек на модель смешения Si-энтальпия [9][10][11].…”
