“…Unique chemical properties of mineral water in Rogaška Slatina are well known (e.g. Lapanje, 2006;Nosan, 1973;Ozim, 1978) and we summarize in this paper only the areas and peculiarities observed now. While other wells have been studied as part of regional research by Trček et al (2011), data on well K-2/75 are published here for the first time.…”

Bottled natural mineral waters from an andesitic aquifer in Slovenia are enriched in magnesium (1.1 g/l), sulphate (2.2 g/l) and dissolved inorganic carbon (204 g/l). We analysed major ions, trace elements, tritium activity, 14C, δ18OH2O, δ2HH2O,δ13CDIC, gas composition and noble gases in six wells. In addition, 87Sr//86Sr, δ34SSO4 and δ11B were analysed here for the first time. Stable isotopes with δ18O = −11.97 to −10.30‰ and δ2H = −77.3 to −63.8 confirm meteoric origin. CO2 degassing is evident at three wells, causing the oxygen shift of about −1.3‰. Tritium activity was detectable only in the shallowest well, where the freshwater component was dated to the 1960s. δ13CDIC in five waters is −1.78 to + 1.33‰, typical of carbonate dissolution. Radiocarbon is low, 1.03–5.16 pMC. Chemical correction with bicarbonate concentration and δ13C correction methods gave best mean residence times, slightly longer than previously published. Sulphate has δ34S 26.6–28.9‰ and δ18O 8.9–11.1‰ due to dissolution of evaporites in carbonate rocks. Boron at concentrations of 1.2–6.1 mg/l has two origins: δ11B = 11.3–16.4‰ from hydrothermal alteration and δ11B = 26.6–31.7‰ from carbonate dissolution. Strontium at concentrations of 0.5–22.0 mg/l has 87Sr//86Sr, indicating three sources: 0.7106 for Miocene clastic rocks, 0.7082 for Triassic carbonates and 0.7070 for Lower Oligocene andesitic rocks. CO2 represents the majority of the dissolved (> 98.84 vol%) and separated gas (> 95.23 vol%). Methane is only found in two wells with a max. of 0.30 vol%. All waters show excess helium and 16–97% of mantle-derived helium. Since all show subsurface degassing, the paleo-infiltration temperature could not be calculated.

“…Jošanička Banja Spa is a unique case where hightemperature waters can be used in cascades as both an energy resource and spa and sports-recreation wellness factor. Remaining similar cases in Europe can be found in Moravske Toplice (Slovenia) [9], Karlovy Vary (Czech Republic) [10], Baile Herculane (Romania) [11]. The data which describe the methodology and results of multi-criteria analysis are also presented in the mentioned papers.…”

The chemical composition of the groundwater is directly dependent on the geological structure, hydrogeological and hydrochemical characteristics and as such it represents an output result of all the factors and processes which take place in the environment within which they were formed. The chemical composition of thermomineral waters often represents a crucial factor in determining the origin, balneological valorization and geothermal potential of the resources. This paper presents the analysis of origin, belneological valorization and geothermal potential of Jošanička Banja Spa, on the basis of the results gained through making the analyisis of chemical contents of the thermomineral waters which occur in the area. The ratio of concentrations of specific chemical components in the thermomineral waters of Jošanička Banja has served as the basic tool for ascertaining the origin of these waters. On the basis of the analysis of the main anion-cation and gas compositions as well as the contents of specific micro-components, a balneological valorization of these resources has been carried out. Apart from that, this paper also presents the calculation of the expected temperatures in the primary geothermal reservoir, which was carried out on the basis of the results of chemical analysis of thermomineral waters that occur in the area. Geothermal potential of about 4 MW t and significant contents of balneologically active components of the chemical composition of these waters, open up a possibility for their multipurpose use, which is also presented in the paper.

“…Mofete so najpogostejše v bližini vulkanov, njihove raziskave potekajo na primer v Kaliforniji (ZDA) (evans et al, 2002) in Romuniji (vaselli et al, 2002), ter na območjih s hidrogeotermalnim sistemi, včasih tudi vezanimi na vulkane. Takšni primeri so jarek Salton v Kaliforniji (ZDA) in Taupo vulkanska cona na Novi Zelandiji (Derrill et al, 1995), Dixie Valley v Nevadi (ZDA) (BergfelD et al, 2001), Liu-Huang-Ku na Tajvanu (Lan et al, 2007) idr. Na nevulkanskih območjih se izviri CO 2 pojavljajo ob izrazitih aktivnih prelomih, kot na primer v Marmara regiji v SZ Turčiji (Doğan et al, 2009) (2015) ugotovili, da se velike količine CO 2 (tudi nad 100 kg/dan) sproščajo iz kotanj, ki so široke manj kot 1 m. Poleg takšnega koncentriranega iztoka se pojavljajo tudi območja z difuznim izhajanjem plina, s posameznimi mehurčki.…”

Izvle~ekPojavi naravnih izvirov CO 2 in vode z veliko prostega plina v Sloveniji so poznani predvsem v Slovenskih goricah. S terenskim delom v letih 2014-2015 smo hidrogeološko opisali enajst izvirov vode in/ali plina: Ihovska slatina, Ivanjševska slatina, Lokavska slatina, Polička slatina, Radvenska slatina, mofeta Rihtarovci, Stavešinske Slepice, Stavešinske mofete Strmec, Ujterska slatina, Verjanska slatina in Žekš. Za pet nezajetih izvirov smo ugotovili, da lahko premer presega 4 m, globina dna pa 2 m, čeprav je njihov obseg večinoma skromnejši. Izdelali smo batimetrične 3D modele izvirnega območja ter na tlorisu označili mesta izhajanja plina in ocenili intenzivnost dotoka po subjektivni, vizualni petstopenjski lestvici. Izmerili smo tudi fizikalno-kemijske parametre vode. Opazovane pojave smo razvrstili med mofete in mineralne vode. Dve sta mokri mofeti (Polička slatina in Slepice), tri pa suhe (mofeta Rihtarovci, mofeta Strmec, mofeta pri Lokavski slatini). Iz njih stalno izhaja hladen CO 2 , površinska ali padavinska voda je kisla, v okolici pa je opazno spremenjeno rastje in/ali gola tla. Mineralna voda z nad 1 g/l skupnih raztopljenih snovi izvira v Ihovski, Ivanjševski in Radvenski slatini ter Žekšu in je bogata s prostim CO 2 z intenzivnostjo izhajanja plina 2-4. Verjanska in Ujterska slatina nista niti mofeti niti mineralni vodi. Prva je mogoče, tako kot večina, slatina, z nad 250 mg/l prostega CO 2 (CO 2 ) g . Povezave med globino dna izvira in intenzivnostjo izhajanja plina na vodni površini nismo našli. AbstractNatural CO 2 springs and groundwater rich in free gas in Slovenia occur mainly in the Slovenske gorice hills. Within the frame of fieldwork performed in 2014-2015 we investigated 11 springs: Ihovska slatina, Ivanjševska slatina, Lokavska slatina, Polička slatina, Radvenska slatina, Mofette Rihtarovci, mofettes Stavešinske Slepice, and Strmec, Ujterska slatina, Verjanska slatina and Žekš. The diameter of five uncaptured springs can exceed 4 m, with depression depths of 2 m, but most are smaller. We elaborated bathymetric 3D models of these spring areas, marked degassing locations in a plan view, and evaluated the gas flux according to a subjective, visual five-level scale. We also measured physicochemical parameters of the water. The observed phenomena were classified among mofettes and mineral waters. Two are wet mofettes (Polička slatina and Slepice) and three dry mofettes (Rihtarovci, Strmec, mofette at Lokavska slatina). These constantly emit cold CO 2 , hold acid surface or meteoric water, and bare soil or changed vegetation may also be present. Mineral water consisting of more than 1 g/l of total dissolved solids surfaces at Ihovska, Ivanjševska and Radvenska slatina, and Žekš. It is rich in free CO 2 , having a flux intensity of 2-4. Verjanska slatina and Ujterska slatina are neither mofettes nor mineral waters. The first, like most others, may be a slatina, having more than 250 mg/l of free CO 2 (CO 2 ) g . We found no connection between the depth of the springs and the intensity of...
