Here, sugarcane filter cake was treated with MgO and H3PO4 at different Mg:P ratios (0.5, 1, 1.5, and 2) followed by pyrolysis at 600 degrees C. The resulting modified biochars were characterized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), and total Mg and P. The extractable P was measured in deionized (DI) water and 2% formic acid, and the kinetic phosphate release in DI water was monitored over 240 h. Increasing the Mg:P ratio in the biochar greatly increased the total and extractable P in 2% formic acid but resulted in a lower kinetic phosphate release in DI water. This was explained by a change in P speciation (from crystalline pyrophosphate towards amorphous orthophosphate) and increase in biochar pH with increasing Mg contents. The higher 2% formic acid-extractable P and lower water-soluble P at high Mg:P ratios suggested that the P is potentially highly available to crops while having a reduced risk for P loss to surface waters. Their high pH makes these Mg- and P-rich biochar-based fertilizers potentially attractive for application in acidic soils.}, keywords = {PHOSPHORUS; MAGNESIUM; PYROLYSIS; fertilizer; BIOCHAR; Sugarcane filter cake}, year = {2023}, eissn = {2190-6823} } @article{MTMT:33734600, title = {Measuring and evaluating colorimetric properties of samples from loess-paleosol sequences}, url = {https://m2.mtmt.hu/api/publication/33734600}, author = {Laag, Ch and Lagroix, F and Kreutzer, S and Chapkanski, S and Zeeden, Ch and Guyodo, Y}, doi = {10.1016/j.mex.2023.102159}, journal-iso = {METHODSX}, journal = {METHODSX}, volume = {10}, unique-id = {33734600}, year = {2023}, eissn = {2215-0161}, orcid-numbers = {Laag, Ch/0000-0002-6012-1029} } @article{MTMT:33692240, title = {From collection or archaeological finds?

The chemists were delivered six coins with neither pre-agreements nor further information on the origin of the coins. Therefore, the request was to hypothetically assign the coins to the two groups on the basis of similarities and differences in their surface composition. Only non-destructive analytical techniques were allowed to be used to characterize the surface of the six coins taken blindly from the two sets. The elemental analysis of each coins’ surface was carried out by µ-XRF. To better observe the morphology of the coins’ surfaces, SEM-EDS was used. Compounds covering the coins coming from both corrosion processes (patinas) and the deposition of soil encrustations were also analyzed by means of the FTIR-ATR technique. The molecular analysis confirmed the presence of silico-aluminate minerals on some coins, unequivocally indicating a provenance from clayey soil. Some soil samples, collected from the archaeological site of interest, were analyzed to verify whether the encrusted layer on coins could contain chemical components compatible with them. This result, together with the chemical and morphological investigations, led us to subdivide the six target coins into two groups. The first group is made up of two coins coming from the set of coins from excavation (found in the subsoil) and from the set from open air finds (coins found in the top layer of the soil). The second group is made up of four coins that are devoid of characteristics corresponding to exposure to soil contact for long periods of time and, moreover, their surface compounds could suggest a different provenance. The analytical results of this study made it possible to correctly assign all six coins to the two groups of finds and support numismatics, which was unconvinced in considering all coins to come from the same finding site only on the basis of archaeological documentations.}, year = {2023}, eissn = {1420-3049}, orcid-numbers = {Crosera, M/0000-0001-5950-093X; Turco, G/0000-0001-5699-2131; Adami, G/0000-0002-1608-2050} } @article{MTMT:33211160, title = {Distribution of organophosphate ester fractions in sediment of the Eastern China Marginal Seas and the influencing factors}, url = {https://m2.mtmt.hu/api/publication/33211160}, author = {Fan, Q and Chen, H and Liao, Q and Zhang, Ch and Ding, Y and Zou, X and Fu, G}, doi = {10.1007/s11356-022-23921-w}, journal-iso = {ENVIRON SCI POLLUT R}, journal = {ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH}, volume = {29}, unique-id = {33211160}, issn = {0944-1344}, year = {2022}, eissn = {1614-7499}, orcid-numbers = {Zou, X/0000-0002-2437-4862} } @article{MTMT:33114592, title = {Relation of the grain size, petrophysical parameters, and Fourier transform infrared analysis of Kusuri sandstones in the Zonguldak subbasin of the West Black Sea, Turkey}, url = {https://m2.mtmt.hu/api/publication/33114592}, author = {Geçer, A}, doi = {10.34049/bcc.54.3.F003}, journal-iso = {BULG CHEM COMMUN}, journal = {BULGARIAN CHEMICAL COMMUNICATIONS}, volume = {54}, unique-id = {33114592}, issn = {0324-1130}, year = {2022}, eissn = {0861-9808}, pages = {235-241} } @article{MTMT:33202963, title = {Tailoring the phosphorus release from biochar-based fertilizers: role of magnesium or calcium addition during co-pyrolysis}, url = {https://m2.mtmt.hu/api/publication/33202963}, author = {Jetsrisuparb, K and Jeejaila, Th and Saengthip, Ch and Kasemsiri, P and Ngernyen, Y and Chindaprasirt, P and Knijnenburg, J T N}, doi = {10.1039/D2RA05848K}, journal-iso = {RSC ADV}, journal = {RSC ADVANCES}, volume = {12}, unique-id = {33202963}, issn = {2046-2069}, abstract = {The addition of MgO in the co-pyrolysis of sugarcane filter cake with H 3 PO 4 resulted in a biochar-based fertilizer with gradual P release over time.

This study is confined to outcrop samples from the submarine-fan sandstones (the L1, L2, and L3 sections) and focuses on documentation of the petrographic characteristics of and depositional controls on reservoir properties of the Haymana Formation sandstones. Analysis of the lithology, texture, sedimentary structure, and petrography of the outcrop samples allows separation of the Haymana Formation sandstones into three distinct lithofacies, A, B, and C. Lithofacies A sandstones exhibit medium-coarse grain sizes (0.4-0.6 mm), moderate-good sorting, and subrounded grains. Lithofacies B sandstones exhibit fine grain sizes (0.2 mm), moderate sorting, and subrounded-subangular grains. Lithofacies C sandstones exhibit very fine grain sizes (0.112 mm) and nonreservoir facies. The main aim of this study is to document the diagenetic history and reservoir quality of the Haymana Formation sandstones. Lithofacies A has the best permeability, ranging from 80 to 120 mD, which can be related to the large grain size, the presence of cross-bedding, small amount of authigenic clays or cements in the pore throats, and enlarged pore apertures. In contrast, Lithofacies B sandstones contain variable yet small pore and pore-throat sizes, which are affected by abundant pore-filling authigenic clays, small grain sizes, and no dissolution. The permeability of the Lithofacies B sandstone ranges from 16 to 35 mD, which is lower than that of the Lithofacies A sandstone. Additionally, the Lithofacies B sandstones have small median pore-throat sizes (mean = 1.52 mu m) and low porosities (average 4-6%), and the Lithofacies A sandstones have large pore-throat sizes (mean = 2.06-3 mu m) and high porosities (average 20-25%), with most pore throats (50% or more) ranging between 1 and 4 mu m. According to these data, the Lithofacies A sandstones show good reservoir characterisation. To date, significant hydrocarbon deposits have not been discovered in the Haymana Formation sandstones, although intensive exploratory work towards this end has been carried out in the Haymana Basin. According to this study, the proximal sandstones of the submarine-fan complex of the Haymana Formation may contain high-potential reservoirs in the Haymana Basin. In the basin, hydrocarbon is sourced from deep zones and may be capped by the proximal part of the Haymana Formation sandstones. According to this study, the Lithofacies B sandstones of the Haymana Formation are not suitable as diagenetic traps for hydrocarbon exploration in the Haymana Basin. However, the Lithofacies A sandstones may be expected to have the highest exploration success.}, keywords = {Permeability; Porosity; hydrocarbon; RESERVOIR; cementation; Fourier transform infrared (FTIR); Submarine fan; Pore throat}, year = {2019}, eissn = {2190-0566}, pages = {1819-1837} } @article{MTMT:30339006, title = {The role of Fe(III) in soil organic matter stabilization in two size fractions having opposite features}, url = {https://m2.mtmt.hu/api/publication/30339006}, author = {Giannetta, B. and Zaccone, C. and Plaza, C. and Siebecker, M.G. and Rovira, P. and Vischetti, C. and Sparks, D.L.}, doi = {10.1016/j.scitotenv.2018.10.361}, journal-iso = {SCI TOTAL ENVIRON}, journal = {SCIENCE OF THE TOTAL ENVIRONMENT}, volume = {653}, unique-id = {30339006}, issn = {0048-9697}, year = {2019}, eissn = {1879-1026}, pages = {667-674} } @article{MTMT:30764201, title = {Mineralogical and geochemical behavior of heated natural carbonate-apatite of the Ypresian series, Maknassy-Mezzouna basin, central Tunisia}, url = {https://m2.mtmt.hu/api/publication/30764201}, author = {Jaballi, F. and Felhi, M. and Khelifi, M. and Fattah, N. and Zayani, K. and Abbes, N. and Elouadi, B. and Tlili, A.}, doi = {10.1007/s13146-019-00519-x}, journal-iso = {CARBONATE EVAPORITE}, journal = {CARBONATES AND EVAPORITES}, volume = {34}, unique-id = {30764201}, issn = {0891-2556}, year = {2019}, eissn = {1878-5212}, pages = {1689-1702} } @article{MTMT:30764268, title = {Sedimentary geochemistry of alluvial overburden in the primary gem deposit of Pelmadulla, Sri Lanka}, url = {https://m2.mtmt.hu/api/publication/30764268}, author = {Jayawardana, D.

The qualitatively and quantitatively determination elements distribution on the surface of samples and chemical composition, as well as the surface morphology of sediments was performed by Scanning Electron Microscopy coupled with Energy Dispersive Spectroscopy. The geochemical properties of sediments were achieved by Attenuated Total Reflectance - Fourier Transform Infrared Spectroscopy, which well-provide information on a wide range of organic and minerogenic components, (e.g., carbohydrates, humic substances, silicates and carbonates). This information is of particular interest for paleolimnological studies because lake sediments are commonly composed of a mixture of various organic and minerogenic compounds originating from the fossilization of tissues and skeletons of aquatic organisms and from the erosion of lake soils. Analysis for a suite of metals rather than just target anthropogenic metals (e.g., Pb, Cu, Zn, Mn, Cd, Fe, Cr, Al and Ni) was accomplished using Inductively Coupled Plasma Mass Spectrometry. High content of several elements including Fe, Ni, Cr, Al and Zn in sediment samples was correlated with their sources. In further studies, it is possible to be identified situations that are or not priori favorable for tracing of these elements using the isotopic approach.}, keywords = {sediment; FTIR; ICP-MS; SEM-EDS; salt lake}, year = {2019}, eissn = {1221-146X} } @article{MTMT:3082983, title = {The relevance of dawsonite precipitation in CO2 sequestration in the Mihályi-Répcelak area, NW Hungary}, url = {https://m2.mtmt.hu/api/publication/3082983}, author = {Király, Csilla and Sendula, Eszter and Szamosfalvi, Ágnes and Káldos, Réka and Kónya, Péter and Kovács, István János and Füri, Judit Izabella and Zsolt, Bendő and Falus, György}, doi = {10.1144/SP435.15}, journal-iso = {GEOL SOC SPEC PUBL}, journal = {GEOLOGICAL SOCIETY SPECIAL PUBLICATIONS}, volume = {435}, unique-id = {3082983}, issn = {0305-8719}, keywords = {CO2; Dawsonite; Mihályi-Répcelak; NW Hungary}, year = {2018}, eissn = {2041-4927}, pages = {405-418}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716} } @article{MTMT:3351641, title = {Fossilized biomats as the possible source of high natural radionuclide content at the jurassic úrkút manganese ore deposit, Hungary}, url = {https://m2.mtmt.hu/api/publication/3351641}, author = {Gyollai, Ildikó and Polgári, Márta Piroska and Biró, Lóránt and Vigh, Tamás and Kovács, Tibor and Pál-Molnár, Elemér}, doi = {10.26471/cjees/2018/013/041}, journal-iso = {CARPATH J EARTH ENVIRON SCI}, journal = {CARPATHIAN JOURNAL OF EARTH AND ENVIRONMENTAL SCIENCES}, volume = {13}, unique-id = {3351641}, issn = {1842-4090}, year = {2018}, eissn = {1844-489X}, pages = {477-487}, orcid-numbers = {Gyollai, Ildikó/0000-0001-8576-0196; Biró, Lóránt/0000-0002-1246-8773; Kovács, Tibor/0000-0003-2606-0397; Pál-Molnár, Elemér/0000-0002-9606-0133} } @article{MTMT:3386063, title = {Shock heterogeneity and shock history of the recently found ordinary Csátalja chondrite in Hungary}, url = {https://m2.mtmt.hu/api/publication/3386063}, author = {Kereszturi, Ákos and Fintor, Krisztián and Gyollai, Ildikó and Kereszty, Z and Szabó, Máté Zoltán and Szalai, Zoltán and Walter, Heléna}, doi = {10.7306/gq.1416}, journal-iso = {GEOL Q}, journal = {GEOLOGICAL QUARTERLY}, volume = {62}, unique-id = {3386063}, issn = {1641-7291}, year = {2018}, eissn = {2082-5099}, pages = {433-446}, orcid-numbers = {Fintor, Krisztián/0000-0003-4794-9419; Gyollai, Ildikó/0000-0001-8576-0196; Szalai, Zoltán/0000-0001-5267-411X; Walter, Heléna/0000-0002-6201-5115} } @article{MTMT:30513302, title = {Infrared spectroscopy methods in reservoir rocks analysis-semiquantitative approach for carbonate rocks}, url = {https://m2.mtmt.hu/api/publication/30513302}, author = {Mroczkowska-Szerszen, Maja and Orzechowski, Mateusz}, doi = {10.18668/NG.2018.11.04}, journal-iso = {NAFTA-GAZ}, journal = {NAFTA-GAZ}, volume = {74}, unique-id = {30513302}, issn = {0867-8871}, abstract = {Experimental results and methodology for mineral composition determination of reservoir rocks by means of Fourier Transformed Infrared Spectroscopy technique (FTIR) was a subject to present in the paper.

The presented approach allows for calibration of FTIR ATR using statistical methods like PCR (Principal Component Regression) or PLS (Partial Least Squares) in order to create efficient and cost saving tool for quantitative and semi-quantitative analysis of reservoir rocks samples. In the paper, 18 surface carbonate rocks samples of limestone and dolomite type belonging to the Paleozoic and Mesozoic age from the Krakow-Czestochowa Upland and Main Dolomite from Fore-Sudetic Monocline were analyzed. FTIR results were qualitatively described by analysis together with tentative assignments of their molecular bonds vibrations assignments are presented and a spectra interpretation for typical carbonates associated minerals. The technical constrains of the methodology resulting from proper method calibration and metal oxide analysis limitations were also discussed. Furthermore the behavior of the PCR and PLS algorithms in case of monomineral samples was commented and the necessity of additional qualitative spectra verification was indicated in this case for the final assessment of quantitative data quality. The quantitative results of FTIR analysis were compared with X-ray diffraction (XRD) quantitative data, part of them has been used as validation data. The accordance of the data series was better than 6% for each analyzed mineral phases excluding the outliers indicated by the analytical algorithm. The method was also successfully applied to the quantitative analysis of shale rocks, however, this part of the research will be presented in a separate paper.}, keywords = {PCR; XRD; PLS; Carbonate rocks; quantitative rock analysis; reservoir rocks analysis; FTIR ATR spectroscopy}, year = {2018}, pages = {802-812} } @article{MTMT:27565787, title = {Unraveling adsorption behavior and mechanism of perfluorooctane sulfonate (PFOS) on aging aquatic sediments contaminated with engineered nano-TiO2}, url = {https://m2.mtmt.hu/api/publication/27565787}, author = {Qian, Jin and Li, Kun and Wang, Peifang and Wang, Chao and Liu, Jingjing and Tian, Xin and Lu, Bianhe and Guan, Wenyi}, doi = {10.1007/s11356-018-1984-4}, journal-iso = {ENVIRON SCI POLLUT R}, journal = {ENVIRONMENTAL SCIENCE AND POLLUTION RESEARCH}, volume = {25}, unique-id = {27565787}, issn = {0944-1344}, year = {2018}, eissn = {1614-7499}, pages = {17878-17889} } @inbook{MTMT:32808633, title = {Advanced experimental techniques in geochemistry}, url = {https://m2.mtmt.hu/api/publication/32808633}, author = {Romanov, V}, booktitle = {Greenhouse gases and clay minerals : enlightening down-to-Earth road map to basic science of clay-greenhouse gas interfaces}, doi = {10.1007/978-3-319-12661-6_5}, unique-id = {32808633}, year = {2018}, pages = {77-94} } @article{MTMT:3266347, title = {Shock-induced alterations in the recently found H chondrite Csátalja meteorite and its implications}, url = {https://m2.mtmt.hu/api/publication/3266347}, author = {Gyollai, Ildikó and Kereszturi, Ákos and Kereszty, Zs. and Szabó, Máté Zoltán and Chatzitheodoridis, E.}, doi = {10.1556/24.60.2017.007}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {60}, unique-id = {3266347}, issn = {1788-2281}, abstract = {Shock-driven annealing of pyroxene and shock deformation of olivine were analyzed in a recently found H chondrite called Csátalja. The most characteristic infrared (IR) spectral shape of shock-annealed sub-grained pyroxene was identified: the strongest peak occurs at 860 cm−1 with a smaller shoulder at 837−840 cm−1, and small bands are at 686, 635−638, and 1,044−1,050 cm−1. The appearance of forbidden bands in pyroxene and shift of band positions to a lower wave number in olivines clearly demonstrate the crystal lattice disordering due to shock metamorphism. The shock annealing produced mixed dark melt along fractures, which consists of feldspar−pyroxene and olivine−pyroxene melt. The dark shock melt at sub-grain boundaries of shocked pyroxenes and along fracture of pyroxenes is characterized by elevated Ca, Na, and Al content relative to its environment, detected by element mapping. So far, shock deformation of pyroxene and olivine was not studied by IR spectroscopy; this method has turned out to be a powerful tool in identifying the mixed composition of shock melt minerals. Further study of shock annealing of minerals, together with the context of shock melting at sub-grain boundaries, will provide a better understanding of the formation of high P–T minerals. http://akademiai.com/doi/pdf/10.1556/24.60.2017.007}, year = {2017}, eissn = {1789-3348}, pages = {173-200}, orcid-numbers = {Gyollai, Ildikó/0000-0001-8576-0196} } @article{MTMT:26108224, title = {Assessing and calibrating the ATR-FTIR approach as a carbonate rock characterization tool}, url = {https://m2.mtmt.hu/api/publication/26108224}, author = {Henry, D G and Watson, J S and John, C M}, doi = {10.1016/j.sedgeo.2016.07.003}, journal-iso = {SEDIMENT GEOL}, journal = {SEDIMENTARY GEOLOGY}, volume = {347}, unique-id = {26108224}, issn = {0037-0738}, year = {2017}, eissn = {1879-0968}, pages = {36-52} } @mastersthesis{MTMT:3321895, title = {Mihályi-Répcelak természetes CO2-előfordulás környezetgeokémiai vizsgálata}, url = {https://m2.mtmt.hu/api/publication/3321895}, author = {Király, Csilla}, doi = {10.15476/ELTE.2017.032}, publisher = {Eötvös Loránd University}, unique-id = {3321895}, keywords = {széndioxid; Doktori disszertáció; Mihályi-Répcelak; környezetgeokémia}, year = {2017} } @article{MTMT:26951879, title = {Multi-analytical characterization of Cucuteni pottery}, url = {https://m2.mtmt.hu/api/publication/26951879}, author = {Oancea, AV and Bodi, G and Nica, V and Ursu, LE and Drobota, M and Cotofana, C and Vasiliu, AL and Simionescu, BC and Olaru, M}, doi = {10.1016/j.jeurceramsoc.2017.07.018}, journal-iso = {J EUR CERAM SOC}, journal = {JOURNAL OF THE EUROPEAN CERAMIC SOCIETY}, volume = {37}, unique-id = {26951879}, issn = {0955-2219}, year = {2017}, eissn = {1873-619X}, pages = {5079-5098} } @article{MTMT:26385511, title = {Phosphoric acid purification through different raw and activated clay materials (Southern Tunisia)}, url = {https://m2.mtmt.hu/api/publication/26385511}, author = {Trabelsi, W and Tlili, A}, doi = {10.1016/j.jafrearsci.2017.02.008}, journal-iso = {J AFR EARTH SCI}, journal = {JOURNAL OF AFRICAN EARTH SCIENCES}, volume = {129}, unique-id = {26385511}, issn = {1464-343X}, year = {2017}, eissn = {1879-1956}, pages = {173-200} } @article{MTMT:3238351, title = {Effects of particle size on the attenuated total reflection spectrum of minerals}, url = {https://m2.mtmt.hu/api/publication/3238351}, author = {Udvardi, Beatrix and Kovács, István János and Fancsik, Tamás and Kónya, Péter and Batori, M and Stercel, F and Falus, György and Szalai, Zoltán}, doi = {10.1177/0003702816670914}, journal-iso = {APPL SPECTROSC}, journal = {APPLIED SPECTROSCOPY}, volume = {71}, unique-id = {3238351}, issn = {0003-7028}, abstract = {This study focuses on particle size effect on monomineralic powders recorded using attenuated total reflection Fourier transform infrared (ATR FT-IR) spectroscopy. Six particle size fractions of quartz, feldspar, calcite, and dolomite were prepared (<2, 2-4, 4-8, 8-16, 16-32, and 32-63 mu m). It is found that the width, intensity, and area of bands in the ATR FT-IR spectra of minerals have explicit dependence on the particle size. As particle size increases, the intensity and area of IR bands usually decrease while the width of bands increases. The band positions usually shifted to higher wavenumbers with decreasing particle size. Infrared spectra of minerals are the most intensive in the particle size fraction of 2-4 mu m. However, if the particle size is very small (<2 mu m), due to the wavelength and penetration depth of the IR light, intensity decreases. Therefore, the quantity of very fine-grained minerals may be underestimated compared to the coarser phases. A nonlinear regression analysis of the data indicated that the average coefficients and indices of the power trend line equation imply a very simplistic relationship between median particle diameter and absorbance at a given wavenumber. It is concluded that when powder samples with substantially different particle size are compared, as in regression analysis for modal predictions using ATR FT-IR, it is also important to report the grain size distribution or surface area of samples. The band area of water (3000-3620cm(-1)) is similar in each mineral fraction, except for the particles below 2 mu m. It indicates that the finest particles could have disproportionately more water adsorbed on their larger surface area. Thus, these higher wavenumbers of the ATR FT-IR spectra may be more sensitive to this spectral interference if the number of particles below 2 mu m is considerable. It is also concluded that at least a proportion of the moisture could be very adhesive to the particles due to the band shift towards lower wavenumbers in the IR range of 3000-3620cm(-1).}, keywords = {QUANTITATIVE-ANALYSIS; SYSTEMS; water content; MINERALS; particle size; infrared spectroscopy; Quartz; Refractive index; ATR-FTIR spectroscopy; ATR FT-IR; Attenuated total reflection Fourier transform infrared}, year = {2017}, eissn = {1943-3530}, pages = {1157-1168}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716; Szalai, Zoltán/0000-0001-5267-411X} } @article{MTMT:26958647, title = {Primenenie infrakrasnoj spektroskopii v petrofizičeskih issledovaniâh (po materialam zarubežnyh publikacij)}, url = {https://m2.mtmt.hu/api/publication/26958647}, author = {Aksel'rod, S M}, journal-iso = {Karotažnik}, journal = {Karotažnik}, volume = {1 (259)}, unique-id = {26958647}, issn = {1810-5599}, year = {2016}, pages = {55-84} } @article{MTMT:3055776, title = {Caprock analysis from the Mihályi-Répcelak natural CO2 occurrence, Western Hungary}, url = {https://m2.mtmt.hu/api/publication/3055776}, author = {Király, Csilla and Szamosfalvi, Ágnes and Zilahi-Sebess, László József and Kónya, Péter and Kovács, István János and Sendula, Eszter and Szabó, Csaba and Falus, György}, doi = {10.1007/s12665-016-5399-6}, journal-iso = {ENVIRON EARTH SCI}, journal = {ENVIRONMENTAL EARTH SCIENCES}, volume = {75}, unique-id = {3055776}, issn = {1866-6280}, abstract = {Caprock integrity is one of the most important factors regarding the long-term safe underground storage of CO2. As a result of geochemical reactions among the caprock mineralogy and CO2 saturated pore water, the physical properties of caprock such as porosity, permeability may change, which could affect its sealing capacity. Natural CO2 occurrences can help to understand these long term reactions under storage conditions on geological timescale. Our study area, the Mihályi-Répcelak natural CO2 occurrence, is believed to be leak-proof system on geological timescale. To identify and understand the mineral reactions in the caprocks we applied XRD, FTIR-ATR and SEM analysis of drill cores derived from the study area. The petrophysical properties of the studied rock samples were determined from the interpretation of geophysical well-logs and grain size distribution. The effective porosity (~4 %), permeability (0.026 mD) and clay content (~80 %) of the drill cores imply that the studied clayey caprocks represent an adequate physical barrier to the CO2. Our analytical results show that dawsonite has formed within the caprocks. In most cases the dawsonite crystallized after albite dissolution. This implies that CO2 or CO2-saturated brine can penetrate into the caprock resulting in mineral reactions and most likely changing the porosity and permeability of the sealing lithology. On the other hand the caprock may react as a geochemical buffer for the CO2 and, at least part of it, can be stored within the caprock as solid phase, thereby increasing the storage capacity of the system. © 2016, Springer-Verlag Berlin Heidelberg.}, keywords = {Carbon Dioxide; Porosity; MINERALS; Pannonian Basin; Grain size and shape; Geochemistry; Lithology; Physical properties; Grain Size Distribution; Petrophysical properties; Buffer storage; Well logging; underground storage; Drills; Core drilling; Geochemical reaction; Natural CO; Caprock; Natural CO2 occurrence; Dawsonite; Caprock analysis; Geology}, year = {2016}, eissn = {1866-6299}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716; Szabó, Csaba/0000-0002-1580-6344} } @article{MTMT:2985787, title = {Experimental-modelling geochemical study of potential CCS caprocks in brine and CO2-saturated brine}, url = {https://m2.mtmt.hu/api/publication/2985787}, author = {Szabó-Krausz, Zsuzsanna and Hellevang, H and Király, Csilla and Sendula, Eszter and Kónya, Péter and Falus, György and Török, Szabina and Szabó, Csaba}, doi = {10.1016/j.ijggc.2015.11.027}, journal-iso = {INT J GREENH GAS CON}, journal = {INTERNATIONAL JOURNAL OF GREENHOUSE GAS CONTROL}, volume = {44}, unique-id = {2985787}, issn = {1750-5836}, abstract = {The work presented in this paper is a part of the evaluation of the saline aquifers of the Pannonian Basin for CO2 geological storage in Hungary.
