“…Besides chemical parameters, stable isotopes of oxygen (δ 18 O) and hydrogen (δ 2 H) in water can also provide information about the recharge areas [25,26], while tritium activity provides information about an average groundwater retention time. A combination of chemical, stable, and radioactive isotope data has often been used for hydrogeological research of thermal and mineral waters, and the same techniques have also been applied in Slovenia [24,27,28]. More and more often, new parameters are being enchanted such as 87 Sr/ 86 Sr and δ 11 B [29].…”

The Alps represent an area where many deep groundwater circulations occur as thermal springs. In the Bled case study, the thermal water temperature, at it is discharged to the surface, is between 19–23 °C. In order to determine the extent (e.g., geometry) and the origin of the pronounced deep circulation system in the Bled area, chemical and isotopic measurements of waters from different hydrogeological systems were performed (e.g., surface water, thermal water, fresh groundwater). Hydrogeochemical methods were used to tie together the above-mentioned parameters. The results have shown that thermal outflow in Bled is determined by the presence of a deep-water circulation system, where the dissolution of carbonates minerals is the main hydrogeochemical process affecting chemical components of natural water flow. The correlation of the major ions suggests that the recharge area is represented by both limestone and dolomite rocks. Moreover, the results of δ18O and δ2H of all samples indicate that the recharge is mainly meteoric precipitation. The recharge altitude was estimated for two sampled fresh groundwater springs. The isotopic compositions of those two springs suggest the range from δ18O = −8.68‰, δ2H = −57.4‰ at an elevation of 629 m to δ18O = −9.30‰, δ2H = −60.1‰ at an elevation of 1216 m. The isotopic analysis has confirmed that the thermal water recharges from altitudes of 1282–1620 m a.s.l.

“…At low temperatures, thermal decomposition of sulfur organic compounds in the early stages of oil maturity is another process that produces a moderate H2S concentration (Martins and Marques 2006). Isotopic studies show that the isotope range of δ 34 S in sulfate in evaporate minerals such as gypsum and anhydrite is + 10-+ 30 per thousand (Claypool et al 1980;Worden and Smalley 1996;Zega et al 2015). Therefore, the source of sulfate in the Kamarderaz anticline water resources is probably the gypsum and anhydrite minerals in the Gs and As formations, producing H2S gas in the presence of hydrocarbon materials, and under the influence of one of the above processes.…”

Changes in the quality of karstic water resources affected by the proximity to sources of salinity such as evaporate formations and oil brine pose major challenges to such water resources, especially in Khuzestan province, Iran. The karstic water resources of the Kamarderaz anticline plunge in Izeh city in Khuzestan province have hampered water supply management in the region. To determine water quality and the causes of water salinity in the study area, the hydrochemical parameters of the existing water resources were accordingly evaluated. To conduct hydrochemical studies, 21 samples were collected from different water sources of Kamarderaz anticline plunge in 2017–2018. To analyze the garnered data, Piper and Durov diagrams, composite graphs, ion exchange graphs, ion correlation diagrams, salinity source diagrams and ion ratios were used. The results showed that SO42−, Cl−, and Ca2+ in the water resources of the study area were likely due to several sources including carbonate minerals, gypsum dissolution, anhydrite, halite as well as oil brine. Besides, Br/Cl, I/Cl ion ratios as well as Br-Cl and SO4-Cl diagrams revealed the mixing of karstic freshwater with oil brine in the region. The result of TOC analysis also showed that hydrocarbon materials were present in the well of Atabaki (WT). Moreover, elemental sulfur and sulfur isotope analysis showed that the process of thermochemical sulfate reduction or bacterial sulfate reduction in the presence of hydrocarbons produced H2S gas, and eventually penetrated the WT and WH1.

“…The name originates from the term "žveplo", which means sulphur in the Slovenian language. While some sulphur springs such as Žveplenica [7,8] and Žvepleni studenec pri Rihtarju have been known in Slovenia for decades and are protected for their natural value, information on the Žvepovnik sulphur spring was only first published in a tourist guide of the Municipality of Ljubno in 2013. At the initiative of the Municipality of Ljubno, the first expert inspection of the studied spring was carried out in 2016 as part of a research study on sulphur springs in Slovenia.…”

We present an integrated approach to characterizing the Žvepovnik sulphur spring, comprising detailed basic geological (mapping), geochemical (physico-chemical, elementary), isotopic (δ2H, δ18O, δ13CDIC, δ34S and 3H), and microbiological analyses. We used a multi-parameter approach to determine the origin of the water (meteoric or deeper infiltration), the origin of the carbon and sulphur, and water retention times. Our special research interest is the origin of the sulphur, as sulphur springs are rare and insufficiently investigated. Our results show that the Žvepovnik spring occurs along the fault near the contact between the dolomite aquifer and overlying shales and volcanoclastic beds. The spring water is the result of the mixing of (1) deeper waters in contact with gypsum and anhydrite and (2) shallow waters originating from precipitation and flowing through the surface carbonate aquifer. The results of δ2H and δ18O confirm local modern precipitation as the main source of the spring. δ13CDIC originates from the degradation of organic matter and the dissolution of carbonates. We therefore propose four possible sources of sulphur: (1) the most probable is the dissolution of gypsum/anhydrite; (2) barite may be a minor source of sulphur; (3) the microbial dissimilatory sulfate reduction; and (4) the oxidation of pyrite as the least probable option.
