Due to their excellent water tightness and strength, cementitious materials are used to build WWTPs. However, the performance of these materials is affected by aggressive environments. There are few in situ experiments in the literature regarding the deterioration of cementitious materials in WWTPs. This paper investigates their deterioration mechanisms in a sewage pumping station and a sand-trap structure of a WWTP. In situ experiment was conducted by exposing cement specimens in both locations for 1, 2, 3 and 7 months. The physical and morphological changes of the specimens were examined using stereo microscopy and scanning electron microscopy, whereas the mineralogical/solid phase changes were examined using X-ray diffraction. The results showed that the specimens from the pumping station formed colored surface products, which were confirmed to be secondary minerals (i.e., gypsum and ettringite), whereas there were no colored surface products in the sand-trap structure. The results demonstrated that cementitious materials subjected to wastewater vapors (in a pumping station) had higher deterioration effects than those subjected to wastewater liquid (in a sand-trap structure), suggesting that the wastewater vapors are more aggressive toward cementitious materials than wastewater liquids.}, year = {2024}, eissn = {2504-477X}, orcid-numbers = {Kashaija, Nedson T./0009-0004-3913-4169; Krett, Gergely/0000-0003-1145-4852; Szabó, Csaba/0000-0002-1580-6344; M Tóth, Erika/0000-0001-9048-5758; Szabó-Krausz, Zsuzsanna/0000-0002-4454-8700} } @article{MTMT:34593448, title = {Genesis of Gabbroic Hosted Copper Mineralisations in the Albanian Mirdita Zone (Kçira, Thirra)}, url = {https://m2.mtmt.hu/api/publication/34593448}, author = {Lovász, Anikó and Kovács, Zoltán and Baloghné Kiss, Gabriella}, doi = {10.3390/min14020195}, journal-iso = {MINERALS-BASEL}, journal = {MINERALS}, volume = {14}, unique-id = {34593448}, abstract = {There is a wide variety of ore deposits in Albania, where 20% of the Cu resources belong to a deposit type of unknown genesis (sulphide-bearing quartz veins in gabbroic rocks). The focus of this paper is on two mineralisations of this type (Kçira and Thirra) in the Mirdita Zone, an ophiolite zone representing the Mesozoic Neotethys Ocean in the Dinarides. Our aim is to understand the ore-forming processes and the genesis of these deposits, which can be used in future exploration projects. According to the petrographical analysis, the host rock suffered propylitic alteration or subgreenschist facies metamorphism. Mineral chemistry of pyrite and epidote suggests a VMS related origin, more precisely, the deeper part of its stockwork feeder zone. The bulk rock geochemical analyses confirms that the mineralisations are classified as mafic-, Cyprus-type VMS deposits. Differences in the geochemical compositions and the corresponding mineralogical observations are attributed to the distinct original geotectonic positions: higher amount of compatible elements (Cr, Ni, V and Cu) occur in Kçira, which formed in a mid-oceanic ridge environment, while incompatible elements (Ag, As, Co and Zn) are more abundant in the Thirra deposit, which formed in a supra-subduction zone setting.}, year = {2024}, eissn = {2075-163X}, orcid-numbers = {Baloghné Kiss, Gabriella/0000-0002-7162-2961} } @article{MTMT:34520931, title = {Rare earth element transport and mineralization linked to fluids from carbonatite systems}, url = {https://m2.mtmt.hu/api/publication/34520931}, author = {Andrade Albuquerque Mororó, Emanuel and Berkesi, Márta and Zajacz, Z. and Guzmics, Tibor}, doi = {10.1130/G51531.1}, journal-iso = {GEOLOGY}, journal = {GEOLOGY}, volume = {x}, unique-id = {34520931}, issn = {0091-7613}, abstract = {Rare earth elements are critical constituents for modern technologies, and some of their largest natural resource deposits are related to carbonatite systems. However, the mechanisms leading to rare earth element mineralization and the role of magmatic fluids in carbonatite systems remain poorly understood. Here, we present the first in situ characterization of fluids and their trace-element compositions in natural carbonatite systems by studying secondary quartz-hosted fluid inclusions from Oldoinyo Lengai volcano. By comparing our data to other fluids and melts from various carbonatite systems, we constructed a model for fluid-mediated rare earth element transport and mineralization. We show that carbonatite-related fluids are rich in alkali-carbonate + sulfate + chloride and CO2, but poor in H2O, and they can be significant carriers of rare earth elements (>1600 ppm). We argue that fluid CO2 contents are essential to preclude or slow down the interaction with wall rock during migration and that fluid-mediated rare earth element mineralization occurs when partial pressure of CO2 decreases in the fluid (i.e., during degassing).}, year = {2024}, eissn = {1943-2682}, pages = {x}, orcid-numbers = {Berkesi, Márta/0000-0003-4380-057X; Guzmics, Tibor/0000-0002-9060-3774} } @article{MTMT:34445854, title = {Surface occurrence of dawsonite and natural CO2 emanation in Covasna, in the Eastern Carpathians: A stable isotope study}, url = {https://m2.mtmt.hu/api/publication/34445854}, author = {Cseresznyés, Dóra and Király, Csilla and Gál, Á and Papucs, A and Kónya, P and Lakos, I and Kovács, Ivett and Rinyu, László and Szamosfalvi, Á and Szabó, Csaba and Falus, György and Czuppon, György}, doi = {10.1016/j.chemgeo.2023.121883}, journal-iso = {CHEM GEOL}, journal = {CHEMICAL GEOLOGY}, volume = {645}, unique-id = {34445854}, issn = {0009-2541}, year = {2024}, eissn = {1872-6836}, orcid-numbers = {Cseresznyés, Dóra/0000-0001-6676-7122; Kovács, Ivett/0000-0001-7015-7909; Szabó, Csaba/0000-0002-1580-6344; Czuppon, György/0000-0002-7231-6042} } @article{MTMT:34412174, title = {Lithostratigraphy of the ignimbrite-dominated Miocene Bükk Foreland Volcanic Area (Central Europe)}, url = {https://m2.mtmt.hu/api/publication/34412174}, author = {Hencz, Mátyás and Biró, Tamás and Németh, Károly and Szakács, Alexandru and Portnyagin, Maxim and Cseri, Zoltán and Pécskay, Zoltán and Szabó, Csaba and Müller, Samuel and Karátson, Dávid}, doi = {10.1016/j.jvolgeores.2023.107960}, journal-iso = {J VOLCANOL GEOTH RES}, journal = {JOURNAL OF VOLCANOLOGY AND GEOTHERMAL RESEARCH}, volume = {445}, unique-id = {34412174}, issn = {0377-0273}, abstract = {This study documents the volcanic evolution of the Miocene silicic Bükk Foreland Volcanic Area (BFVA), Northern Hungary (Central Europe) at an event-scale. The BFVA is a deeply eroded and dissected volcanic field dominated by multiple, several 10-m thick, valley-filling silicic ignimbrite units, which are chemically and texturally very similar to each other. Hence, establishing lateral correlation is a real challenge due to the sporadic and small-scale outcrops and lack of stratotypes. Detailed field observations allowed us to identify eleven lithological members including fourteen eruption events and establish a nearly complete lithostratigraphic correlation between fifteen outcrops across the BFVA. Primary pyroclastic material of each member was sampled, and volcanic glass was analyzed for major and trace element composition. The geochemical results confirm the field-based classification of the members and enable the correlation of distinct outcrops. The major and trace element composition of the glassy pyroclasts of each member of the BFVA served as basis to create a field-wide chemical reference database for regional correlational studies. Here, a new lithostratigraphic classification scheme consisting of one formation and eleven members is presented, which reflects the challenges unraveling the stratigraphy of ancient volcanic terrains. The field-based event-scale lithostratigraphy of the BFVA suggests a wet, partly sea-covered depositional environment in the close vicinity of the eruption centers providing favorable conditions to ‘fuel’ silicic explosive phreatomagmatism. On the contrary, paleosol horizons formed after almost each major eruption event or sequence suggests an overall near-coast terrestrial environment for the BFVA, where the emplacement of the pyroclastic material occurred.}, keywords = {STRATIGRAPHY; phreatomagmatism; ignimbrite; Correlation; lithostratigraphy; Glass geochemistry; Volcanic geology; Reworked pyroclasts}, year = {2024}, eissn = {1872-6097}, orcid-numbers = {Hencz, Mátyás/0000-0001-9716-5714; Biró, Tamás/0000-0001-5198-7210; Szabó, Csaba/0000-0002-1580-6344; Karátson, Dávid/0000-0003-0386-1239} } @article{MTMT:33785006, title = {Formation of amphibole lamellae in mantle pyroxene by fluid-mediated metasomatism: A focal plane array FTIR study from the Carpathian-Pannonian region}, url = {https://m2.mtmt.hu/api/publication/33785006}, author = {Liptai, Nóra and Lange, Thomas Pieter and Patkó, Levente and Aradi, László Előd and Berkesi, Márta and Peter, M.
