Identification and quantification of minerals by ATR FTIR is implemented on a set of powdered natural sediments from a loess landslide (Kulcs, Hungary). A protocol including sample preparation, analytical conditions and evaluation of sediment ATR spectra is outlined in order to identify and estimate major minerals in sediments. The comparison of the defined FTIR parameters against qualitative and quantitative results of X-ray diffraction and thermal analysis was used to validate the use of ATR FTIR spectroscopy for the considered sediments. The infrared band areas and their ratios (water/carbonates; silicates/carbonates; kaolinite) appear to be the most sensitive parameters to identify strongly weathered sediments such as paleosols and red clays which most likely facilitate sliding and could form sliding zones. The effect of grain size and orientation of anisotropic minerals on the wave number and intensity of some major absorption bands is also discussed.}, keywords = {Hungary; SEDIMENTS; grain size; landslides; ATR FTIR; landslide; Attenuated total reflectance Fourier transform infrared spectroscopy; Landslide areas; Anisotropy of calcite}, year = {2014}, eissn = {1879-0968}, pages = {1-14}, orcid-numbers = {Kovács, István János/0000-0002-3488-3716; Szabó, Csaba/0000-0002-1580-6344; Szalai, Zoltán/0000-0001-5267-411X} } @article{MTMT:2766646, title = {Mantle-related CO2, metasedimentary HC-N2 gas and oil traces in the Répcelak and Mihályi accumulations, W-Hungary-mixing of three fluids of very different origin}, url = {https://m2.mtmt.hu/api/publication/2766646}, author = {Vető, István and Csizmeg, János and Sajgó, Csanád}, doi = {10.1556/CEuGeol.57.2014.1.3}, journal-iso = {CENT EUR GEOL}, journal = {CENTRAL EUROPEAN GEOLOGY}, volume = {57}, unique-id = {2766646}, issn = {1788-2281}, year = {2014}, eissn = {1789-3348}, pages = {53-69} } @article{MTMT:2154674, title = {Progradation of the paleo-Danube shelf margin across the Pannonian Basin during the Late Miocene and Early Pliocene}, url = {https://m2.mtmt.hu/api/publication/2154674}, author = {Magyar, Imre and Radivojević, D and Sztanó, Orsolya and Synak, R and Ujszászi, K and Pócsik, M}, doi = {10.1016/j.gloplacha.2012.06.007}, journal-iso = {GLOBAL PLANET CHANGE}, journal = {GLOBAL AND PLANETARY CHANGE}, volume = {103}, unique-id = {2154674}, issn = {0921-8181}, abstract = {The basin of giant Lake Pannon in Central Europe was filled by forward accretion of sediment packages during the Late Miocene and Early Pliocene. Successive positions of the shelf-margin are represented by a series of clinoforms in seismic profiles. The height of the clinoforms (and thus the inferred paleo water depth) is 200-600 m in the successions; the width of the slope, measured from the shelf-break down to the toe of slope, varies between 5 and 15 km. Geographical position of successive shelf-margin slopes indicates that about 2/3 of the basin area was filled by sediment transport systems supplying sediments from the NW, from the Alps and Western Carpathians. The first shelf-margin slope was built by the paleo-Danube in the Kisalföld/Danube sub-basin about 10 Ma ago, and during the subsequent 6 Ma it prograded ca. 400 km to the SE across the Pannonian Basin, with an average of 67 km/Ma slope advance. The most significant agent of this shelf growth was the sediment dispersal system of the paleo-Danube, hence we designate this northwestern shelf the paleo-Danube shelf. The northeastern part of Lake Pannon was filled by the paleo-Tisza system, supplying sediments from the Northeastern and Eastern Carpathians. Additional local systems carried sediments from E to W along the eastern margin and S to N along the southern margin of the Pannonian Basin, respectively. The deep-water environment disappeared from the Pannonian Basin and the endemic, brackish biota of Lake Pannon went extinct probably 4 Ma ago, when the paleo-Danube shelf margin and a (yet unidentified) shelf margin prograding in the opposite direction met in the southeastern corner of the Pannonian Basin. © 2012 Elsevier B.V.

That is the reason for the efforts made by the developed countries to reduce their CO2 emissions. One of the tools to signifi cantly decrease the emission of industrial point sources is to capture the CO2 from their fl ue gas, and sequester it safely in a geological system under the surface (CCS: carbon capture and sequestration). Amongst these geological formations deep saline aquifers have the biggest storage capacity, therefore the examination of processes occurring during and after CO2 injection is essential to guarantee the safety necessary for long term CCS projects. This paper presents the results of a cooperative research project by Eötvös Loránd University, Budapest University of Technology and Economics, and Eötvös Loránd Geophysical Institute of Hungary about the examination of the processes mentioned above. © 2012 Magyar Geofi zikusok Egyesülete.}, keywords = {Carbon Dioxide; Pannonian Basin; AQUIFER; Carbon sequestration; carbon emission; geochemical cycle; industrial emission; underground storage}, year = {2012}, eissn = {2677-1497}, pages = {258-266}, orcid-numbers = {Kózelné Székely, Edit/0000-0002-6935-0071; Szabó, Csaba/0000-0002-1580-6344} }
