“…Pezdič (1991) omenja, da na več mestih vzdolž Boračevskega preloma od Negove do Radencev izhaja praktič-no suh plin CO 2 (100 vol.% CO 2 ) medtem ko ima v okolici povprečno 1 vol.% primesi (N 2 , CH 4 , H 2 S…). Zelo čist CO 2 je tudi v Ščavniški dolini (Pezdič, 1991;Bräuer et al, 2016). Drugi avtorji omenjajo, da se izloča vzdolž prepustnih con Rabskega preloma (kralJ & kralJ, 2000;laPanje, 2006.…”

“…Čeprav Žlebnik (2009) meni, da plinski CO 2 migrira skupaj z vodo ter s tem povečuje njeno mineralizacijo, najnovejše raziskave vsebnosti helija in žlahtnih plinov v plinu v Slepicah in mineralni in termomineralni vodi v Radencih, opravljene v letih 2013 in 2014, dokazujejo prevladujoč dotok plina iz plašča (Bräuer et al, 2016). Avtorji potrjujejo tudi sklepanja predhodnikov (Pezdič, 1991;lapanje et al, 2007;kralj et al, 2009), da plin prodira proti površini ob prelomih in ločeno od podzemne vode ter se koncentrira pod plitvejšimi, zelo slabo prepustnimi plastmi.…”

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...

“…As a contribution in the explanation of the As content -in fact As capture -in the organic matter in the Pannonian Basin may serve a very interesting work of Bräuer et al (2016). Reading their explanation it becomes reasonable to suppose that As was maybe the result of degassing of the Earth's mantle and later "catching" to organic matter and/or its admixtured inorganic matter (see the concept of CAI -Coal Affinity Index, ketris & Yudovich, 2009).…”

High contents of arsenic (As) in coal samples from four localities within Neogene deposits of the Pannonian Basin in Slovenia are presented and discussed in this paper. Data from three localities represent interval samples of coal cuttings from wells TER-1 (Terbegovci), Sob-3g (Murska Sobota), and MD-1 (Mislinjska Dobrava). The fourth locality is Globoko, where the main lignite seam was analysed already in 1989. The oldest are coal samples from the MD-1 well which are supposed to be of the Lower Miocene age (except for the shallowest one, which is of the Plio-Quaternary age). Coal samples from the TER-1 and Sob-3g wells are of the Upper Miocene age (Mura Formation). The lignite sample from Globoko is of the Upper Miocene age too (Pontian; Globoko Formation). Most samples were prepared for the ICP-MS method analysis as "whole coal", dry, pulverized lab-samples, weighting ca. 10 g. The results show for all "whole coals" samples considerably increased contents of As: 22.7, 111.4, 222.1, and 131.4 µg/g for the Lower Miocene (?), and 84.5 µg/g for the Plio-Quaternary coals from MD-1 well, 392 µg/g for coals from the Sob-3g well, and 116 µg/g for a coal from the TER-1 well (both Upper Miocene -Mura Formation). In the case of Globoko, not "whole coal" but its high temperature ash was analysed and showed As content as high as 170 µg/g applying AAS method of analysis, and even 260 µg/g applying the ICP-MS. Origin of As could be pre-Neogene rocks of the hinterland and/or Neogene calc-alkaline volcanites. Mineral-gas exhalations from the under-continental upper mantle, containing As, could also be a source of this highly volatile element. IzvlečekV članku predstavljamo in razlagamo rezultate o visoki vsebnosti arzena (As) v vzorcih premoga iz štirih lokalnosti znotraj neogenskih plasti na območju Panonskega bazena v Sloveniji. Podatki iz treh lokalnosti predstavljajo intervalne vzorce drobcev premoga iz vrtin TER-1 (Terbegovci), Sob-3g (Murska Sobota) in MD-1 (Mislinjska Dobrava). Četrta lokalnost je Globoko, kjer je bil glavni lignitni sloj analiziran že leta 1989. Najstarejši premog je iz vrtine MD-1 in je spodnjemiocenske starosti, razen najzgornejšega vzorca, ki je pliokvartarne starosti. Premogi iz vrtin TER-1 in Sob-3g so zgornjemiocenske starosti (Murska formacija). Lignit iz Globokega je tudi zgornjemiocenske starosti, določneje, pontijske (Globoška formacja). Večina vzorcev je bila pripravljena za analizno metodo ICP-MS kot vzorcev »celotnega premoga«. Laboratorijski vzorci so bili suhi, uprašeni in so tehtali okoli 10 g. Rezultati so pokazali za celotne premoge naslednje vsebnosti As: 22,7; 111,4; 222,1 in 131,4 µg/g za spodnjemiocenske premoge in 84,5 µg/g za plio-kvartarni premog iz vrtine MD-1 ter 392 µg/g za premoge iz vrtine Sob-3g in 116 µg/g za premog iz vrtine TER-1. Lignit iz Globokega je bil analiziran kot visokotemperaturni pepel z metodama AAS in ICP. Prva je pokazala vsebnost As 170 µg/g, druga pa 260 µg/g. Izvore As in njegove vezave na organsko/mineralno premoško snov je iskati v pred-neog...

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.
