We handled the fluctuations in voxel porosity averages over unequal depth distributions as signals over uneven time intervals. The strength of wavelet analysis lies in the ability to study the fluctuation of a signal in detail, i.e., the wavelet transforms permit automatic localization of the cyclic attributes' sequences both in time (the depth domain) and according to their frequency (the frequency domain). Thereupon, three main frequency branches (cycles) were discerned: small scale (5, 6.67, and 11 cm), intermediate scale (20, 30 cm), and large scale (66.67 cm). Depending on the CWT coefficients magnitude plot, we were able to detect the developments of porosity oscillation according to the depth variable. Thus, small-scale cycles were seen throughout the core sample., the intermediate-scale cycles were strong in the upper parts of the core sample and dwindled toward greater depths, and the large cycle was predominant in the lower part of the core sample. The cross-correlation of the wavelet coefficients of porosity and rock-forming components allows a detailed study of the inter-dependence of such parameters as their relationship changes over time. The distinct peaks at zero lag indicates that the measured wavelet coefficient series were contemporaneously correlated; their strong positive correlations suggest that both examined series respond similarly and simultaneously to other exogenous factors. The results emphasize that cyclical porosity fluctuations at all scales would concern three main factors; sediment deposition, diagenetic processes, and structural deformation (i.e., convolute laminations).}, year = {2023}, eissn = {1333-4875}, pages = {131-146}, orcid-numbers = {Abutaha, Saja/0000-0001-8439-5895; Geiger, János/0000-0001-9359-5266; Gulyás, Sándor/0000-0002-3384-2381} } @article{MTMT:33832012, title = {Adsorption and diffusion of selenite on Boda Claystone Formation}, url = {https://m2.mtmt.hu/api/publication/33832012}, author = {Czömpöly, Ottó Sámuel and Fábián, Margit and Korányi, Tamás and Nagy, Gábor and Horváth, Zsolt Endre and Zizak, I. and Pollastri, S. and Aertsens, M. and Osán, János}, doi = {10.1016/j.clay.2023.106997}, journal-iso = {APPL CLAY SCI}, journal = {APPLIED CLAY SCIENCE}, volume = {241}, unique-id = {33832012}, issn = {0169-1317}, year = {2023}, eissn = {1872-9053}, orcid-numbers = {Horváth, Zsolt Endre/0000-0002-4632-0136} } @article{MTMT:34151030, title = {Geochemical and Sedimentological Signatures of Ariyankuppam and Chunnambar Estuarine Sediments, Pondicherry, India: Implications on Weathering and Provenance}, url = {https://m2.mtmt.hu/api/publication/34151030}, author = {Kirubakaran, N. and Sridharan, M. and Senthil Nathan, D. and Rajamanickam, M. and Harikrishnan, S.}, doi = {10.1007/s12594-023-2461-3}, journal-iso = {J GEOL SOC INDIA}, journal = {JOURNAL OF THE GEOLOGICAL SOCIETY OF INDIA}, volume = {99}, unique-id = {34151030}, issn = {0016-7622}, year = {2023}, eissn = {0974-6889}, pages = {1275-1284} } @article{MTMT:33698292, title = {Using geophysical log data to predict the fracture density in a claystone host rock for storing high-level nuclear waste}, url = {https://m2.mtmt.hu/api/publication/33698292}, author = {Tóth, Emese and Hrabovszki, Ervin and M.

A crucial step for characterizing the hydrodynamic behavior of such a fractured reservoir is fracture identification and accurate calculation of the fracture density. Although acoustic borehole televiewers provide a reliable base for determining the fracture density, older boreholes usually lack such data. However, conventional borehole geophysical measurements are often accessible in such cases. The aim of this study was to identify any correlations between well log data and fracture density. Multiple linear regression analysis was performed on data from two boreholes penetrating the Boda Claystone Formation in southwest Hungary. The upper section of the BAF-4 borehole was used for training, where the fracture density was estimated with a fit of R 2 = 0.767. The computed regression function predicted the fracture density with high accuracy in both boreholes for all intervals with typical lithological features. However, in some sections where anomalous well log data indicated changes in the lithology, the prediction accuracy decreased. For example, the function underestimated the fracture density in sandy intervals.}, year = {2023}, eissn = {2213-5820}, pages = {35-51}, orcid-numbers = {Hrabovszki, Ervin/0000-0001-7914-6042; M.

The goal of this work is to determine the distribution and origin of the local natural background contents of these toxic elements. Concentrations of As and Sb in different Lower Permian to Lower Triassic lithostratigraphic units are higher than the normal global ranges represented by the Upper Continental Crust composition (1.5 and 0.2 mg/kg, respectively). In the studied mudrock samples, the median values for As and Sb range from 3.5 to 30.5 mg/kg, and from 1.1 to 2.0 mg/kg, respectively. In the sandstone samples, the median As contents range from 2.3 to 20.5 mg/kg, while the values for Sb range from 0.4 to 0.9 mg/kg. The highest metalloid contents were found in the Upper Permian Cserdi and Boda formations, which could be only of local importance as a source of As in the contamination process of soils and natural waters. The relatively enhanced metalloid content of these rocks could be related to hydrothermal activity in the region.

Samples representing the dominant rock types of BCF were studied: albitic claystone, claystone with high illite content, and analcime bearing claystone. Clay minerals in these three rock types were characterized by Xray powder diffraction (XRD), transmission electron microscopy (TEM) and thermal analysis (DTA-TG), and the results were discussed from the point of view of the radionuclide sorption properties being studied in the future. Mineral compositions of bulk BCF samples vary in wide ranges. In the albitic sample, besides the dominant illite, few percent of chlorite represents the layer silicates in the clay fraction. Illite is the dominating phase in the illitic sample, with a few percent of chlorite. HRTEM study revealed that the thickness of illite particles rarely reaches 10 layers, usually are of 5-6 TOT layer thick. Illite crystals are generally thicker in the albitic sample than in the illitic one. The significant difference between the clay mineral characterisitics of the analcimous and the other two samples is that the former contains regularly interstratified chlorite/smectite beside the dominant illite. Based on the structural and chemical data two illite type minerals are present in the BCF samples: 1M polytype containing octahedral Fe and Mg besides Al, 2M polytype illite generally is free of Fe andMg. Close association of very thin illite plates and nanosized hematite crystals is typical textural feature for BCF. The goal of this study is to provide solid mineralogical basis for further studies focusing on radionuclide sorption properties. © 2016 T.

A country-wide screening found this 800–1000 m thick succession the most suitable for the disposal of high-level radioactive waste in Hungary, and research into this formation has consequently been intensified since. The investigations included a detailed study of the sedimentological characteristics. Data obtained by mapping of the 25 km2 outcrop area of the formation and from more than 40 boreholes were processed. The sedimentary structures were investigated on outcrop to microscopic scales, and cycles in the succession were interpreted. The main lithofacies, sedimentary structures and ichnofossils are presented. They indicate that the major part of the succession was deposited in a playa mudflat and is not of lacustrine origin in a strict sense. The lake sediments are represented by laminated and ripple-marked/flaser-type cross-laminated claystones and siltstones and by massive dolomites; trace fossils include crawling traces and burrows. Partial or complete drying out of the lake commonly occurred after the formation of carbonate mud by evaporation. Periodic fluvial influx is recorded by cross-bedded sandstones and unsorted gravelly sandstones of up to pebble-sized angular grains. Fenestral and stromatolitic structures reflect the repeated appearance of playa mudflat conditions. The silty claystones, which compose the major part of the succession, lost their primary structures due to pedogenic processes and indicate prolonged subaerial intervals with soil formation and only ephemeral inundations. The presence of pedogenic carbonate concretions supports the interpretation of an arid climate and a relatively shallow groundwater table. Drying-out events shown by desiccation cracks and authigenic breccias can be traced all over the succession. The various facies form small-scale sedimentary cycles showing a shallowing-upward trend and the growing influence of aridity and subaerial exposure.}, year = {2010}, eissn = {2080-6574}, pages = {27-41}, orcid-numbers = {Sebe, Krisztina/0000-0002-4647-2199; Halász, Amadé/0000-0003-4582-8883} } @mastersthesis{MTMT:26146067, title = {Stroncium, cézium, kobalt és jód szorpciójának és migrációjának vizsgálata agyagkőzet mintákon és nagy dózisok detektálására alkalmas termolumineszcens anyag kifejlesztése}, url = {https://m2.mtmt.hu/api/publication/26146067}, author = {Mell, P}, unique-id = {26146067}, year = {2010} } @article{MTMT:1593074, title = {Preliminary results on the Co, Sr and Cs sorption properties of the analcime-containing rock type of the Boda Siltstone Formation}, url = {https://m2.mtmt.hu/api/publication/1593074}, author = {Sipos, Péter and Németh, Tibor and Máthé, Zoltán}, doi = {10.1556/CEuGeol.53.2010.1.4}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {53}, unique-id = {1593074}, issn = {1788-2281}, year = {2010}, eissn = {1789-3348}, pages = {67-78}, orcid-numbers = {Sipos, Péter/0000-0002-8746-0573; Németh, Tibor/0000-0002-1836-6006} } @article{MTMT:1299028, title = {A felső-permi Cserdi Konglomerátum Formáció kavicsanyagának kőzettani és geokémiai vizsgálati eredményei (XV. szerkezetkutató fúrás, Ny-Mecsek)}, url = {https://m2.mtmt.hu/api/publication/1299028}, author = {Bodor, Sarolta and Szakmány, György}, journal-iso = {FÖLDTANI KÖZLÖNY}, journal = {FÖLDTANI KÖZLÖNY}, volume = {139}, unique-id = {1299028}, issn = {0015-542X}, year = {2009}, eissn = {2559-902X}, pages = {325-340}, orcid-numbers = {Szakmány, György/0000-0002-9557-2030} } @article{MTMT:2251164, title = {Izotópmigrációs vizsgálatok a Bodai Aleurolit Formáció kőzetmintáin}, url = {https://m2.mtmt.hu/api/publication/2251164}, author = {Lázár, Károly and Máthé, Zoltán and Megyeri, János and Mell, P and Szarvas, Tibor}, journal-iso = {MAGY KÉM FOLY KÉM KÖZL}, journal = {MAGYAR KÉMIAI FOLYÓIRAT - KÉMIAI KÖZLEMÉNYEK (1997-)}, volume = {115}, unique-id = {2251164}, issn = {1418-9933}, year = {2009}, eissn = {1418-8600}, pages = {129-133} } @mastersthesis{MTMT:1337382, title = {A dél-dunántúli paleozoos–alsó-triász sziliciklasztos kőzetek kőzettani és geokémiai vizsgálatának eredményei}, url = {https://m2.mtmt.hu/api/publication/1337382}, author = {Raucsikné Varga, Andrea Beáta}, publisher = {Eötvös Loránd University}, unique-id = {1337382}, year = {2009}, orcid-numbers = {Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482} } @inbook{MTMT:1325257, title = {Metaüledékes képződmények a Tiszai-egység aljzatában: a felső-paleozoikumi Túronyi Formáció (Szlavóniai-Drávai-terrénum)}, url = {https://m2.mtmt.hu/api/publication/1325257}, author = {Raucsikné Varga, Andrea Beáta and Raucsik, Béla}, booktitle = {Magmás és metamorf képződmények a Tiszai Egységben}, unique-id = {1325257}, abstract = {Tanulmányunkban a Villányi-hegység északi előterében (Szlavóniai-Drávai-terrénum, Villányi zóna) feltárt, bizonytalan rétegtani besorolású Túronyi Formáció metaüledékes rétegsorát mutatjuk be.

In the course of in-diffusion measurements 4.7.10(-11) m(2)/s, during through-diffusion investigations 1.4 - 1.6.10(-12) m(2)/s and at in situ conditions 5.0 - 8.0.10 - 12 m(2)/s apparent diffusivities were obtained for I-125. Modest sorption of I-125 can also be deduced from the results.}, year = {2006}, eissn = {1588-2780}, pages = {411-417} } @article{MTMT:1080856, title = {Sorption of Co, Cs, Sr And I Onto Argillaceous Rock as Studied by Radiotracers}, url = {https://m2.mtmt.hu/api/publication/1080856}, author = {Mell, P and Megyeri, János and Riess, L and Máthé, Zoltán and Csicsák, J and Lázár, Károly}, doi = {10.1007/s10967-006-0177-7}, journal-iso = {J RADIOANAL NUCL CHEM}, journal = {JOURNAL OF RADIOANALYTICAL AND NUCLEAR CHEMISTRY}, volume = {268}, unique-id = {1080856}, issn = {0236-5731}, year = {2006}, eissn = {1588-2780}, pages = {405-410} } @article{MTMT:1203520, title = {A Bodai Aleurolit Formáció törmelékes kőzettípusainak ásványtani, kőzettani és geokémiai jellemzői [Mineralogical, petrological and geochemical characteristics of the siliciclastic rock types of Boda Siltstone Formation]}, url = {https://m2.mtmt.hu/api/publication/1203520}, author = {Raucsikné Varga, Andrea Beáta and Raucsik, Béla and Szakmány, György and Máthé, Zoltán}, journal-iso = {FÖLDTANI KÖZLÖNY}, journal = {FÖLDTANI KÖZLÖNY}, volume = {136}, unique-id = {1203520}, issn = {0015-542X}, year = {2006}, eissn = {2559-902X}, pages = {201-231}, orcid-numbers = {Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482; Raucsik, Béla/0000-0002-1951-5974; Szakmány, György/0000-0002-9557-2030} } @inproceedings{MTMT:26146053, title = {Application of the Fuzzy Set Theory for the Quantitative Phase Analysis of Rocks Using Thermal Analysis Applied to the Boda Siltstone Formation, Hungary}, url = {https://m2.mtmt.hu/api/publication/26146053}, author = {Földvári, M}, booktitle = {6th International Symposium of Hungarian Researchers on Computational Intelligence : proceedings}, unique-id = {26146053}, year = {2005}, pages = {1-7} } @article{MTMT:1338185, title = {Az őskörnyezeti viszonyok jellemzése a törmelékes üledékes kőzetek kémiai összetétele alapján [Characterization of palaeoenvironment based on chemical composition of siliciclastic sedimentary rocks]}, url = {https://m2.mtmt.hu/api/publication/1338185}, author = {Raucsikné Varga, Andrea Beáta}, journal-iso = {FÖLDTANI KÖZLÖNY}, journal = {FÖLDTANI KÖZLÖNY}, volume = {135}, unique-id = {1338185}, issn = {0015-542X}, year = {2005}, eissn = {2559-902X}, pages = {433-458}, orcid-numbers = {Raucsikné Varga, Andrea Beáta/0000-0002-8673-1482} }
