Chemical composition and saturation degree of the Annenskiy thermal waters to minerals of water-bearing rock have been considered in the manuscript. It is shown that the thermal waters are low mineralized, alkaline and belong to HCO3-Na type. The thermal waters-rock system is equilibrium-nonequilibrium. It means that the waters dissolve primary minerals continuously, never reaching saturation (anorthite, K-field spar and etc.), and form new secondary mineral phases simultaneously, reaching saturation (gibbsite, montmorillonite, albite and etc.). Besides, peculiarities of the equilibrium with minerals of water-bearing rocks for surface and ground waters of the studied region was considered. It is established that the thermal waters are ahead of surface and ground waters and represent the certain stage of the water-rock system evolution. The stage is characterized by the certain chemical composition (TDS=148-317 mg/L, HCO3-Na, SiO2=9-80 mg/L), complex of secondary minerals (calcite, albite, laumontite and etc.) and special geochemical environment (pH 8.2-8.6).

Abstract. Hydrothermic features in Galicia (northwest Spain) have been used since ancient times for therapeutic purposes. A characterization of these thermal waters was carried out in order to understand their behaviour based on inorganic pattern and water-rock interaction mechanisms. In this way 15 thermal water samples were collected in the same hydrographical system. The selected thermal water samples were classified using principal component analysis (PCA) and partial least squares (PLS) regression analysis in two groups according to their chemical composition: group I with the young water samples and group II with the samples with longest water-rock contact time. This classification agreed with the results obtained by the use of geothermometers and hydrogeochemical modelling, where the samples were classified into two categories according their residence time in the reservoir and their water-rock interaction.

<p><strong>Abstract.</strong> Southeastern Idaho exhibits numerous warm springs, warm water from shallow wells, and hot water from oil and gas test wells that indicate a potential for geothermal development in the area. We have estimated reservoir temperatures from chemical composition of thermal waters in southeastern Idaho using an inverse geochemical modeling technique (Reservoir Temperature Estimator, RTEst) that calculates the temperature at which multiple minerals are simultaneously at equilibrium while explicitly accounting for the possible loss of volatile constituents (e.g., CO<sub>2</sub>), boiling and/or water mixing. The temperature estimates in the region varied from moderately warm (59<span class="thinspace"></span>°C) to over 175<span class="thinspace"></span>°C. Specifically, hot springs near Preston, Idaho, resulted in the highest reservoir temperature estimates in the region.</p>

Due to the drilling works carried out through 1970-1980s, the oil-gas bearing content of Dalimammadli and Tarsdallar structures has been studied. According to the conducted researches, thermal waters with high recovery rate and temperature more than 60 оC at the wellhead have been revealed. By chemical composition these waters are predominantly of chloride-sodium, and in Gazanbulag area – chloride-calcium (Са > 50 %) character. The main microcomponents are iodine, bromine, borium, etc. In this regard, the health centers (Goran, Gazanbulag, etc.) have been constructed in this area.

In the article, in the socio-geographical direction, issues are discussed about the territory of mineral and thermal waters on the southern slope of the Greater Caucasus, the chemical composition of waters, temperature, the possibility of using it in the treatment of some diseases, ecotourism value and rational use of thermal waters. Ecotourism can provide real financial support for nature conservation and increase the importance of natural sites that should be preserved in their original form. For the rational use of thermal waters in the research area, targeted measures should be taken at the state level, in order to eliminate the shortages in this area and to ensure its further development, entrepreneurs should be provided with very low interest rates, long-term loans. In the study of thermal and mineral waters, the merit of geologists, hydrogeologists and balneologists was great; in the modern period, scientists and specialists mainly refer to information obtained 50-100 years ago. There are very few innovations in this area. Favorable climatic conditions of the region, ecotourism conditions, large forests, natural and historical monuments, high seismicity of the territory, deforestation processes, and so on. according to specifications differ. The study area (especially the Gakh region) is the region with the richest thermal and mineral water resources in Azerbaijan, as well as ecotourism and balneological tourism. The Gakh region in the northwestern part of Azerbaijan, along with other natural benefits, is distinguished by its thermal and mineral springs and balneological value. The well-known hydrogen sulfide, hydrocarbonate groups of the Ilisu thermal waters, as well as the resort-tourist and balneological significance of the mineral springs on the left and right banks of the Kurmukh River near the village of Alibeyli and in the so-called boiling zone have not yet been fully utilized. Thermal and mineral waters, with the exception of a few, were used in a very primitive form mainly by the local population. The use of such waters should be carried out under the supervision of a physician for his purpose, and the taking or not taking medicinal baths should be especially controlled. Therefore, the chemical composition of thermal waters must be periodically checked by professional specialists.
