This study aims to reconstruct the latest Jurassic–earliest Cretaceous palaeoenvironment and its evolution in the area of the Transdanubian Range (Hárskút and Lókút successions, Hungary), and provide new data on the relation between climate changes, palaeoceanography and marine ecosystems. Herein, calcareous nannofossil and geochemical data are presented and put into a geochronological framework in order to evaluate and compare palaeoenvironmental signals recorded in the two studied successions; the resultant scenario is compared with published literature data from both the western Tethyan region and northern Europe. Accordingly, in the Transdanubian Range, the relatively humid climate of the early Tithonian was followed by the late Tithonian–early Berriasian arid phase and the late Berriasian humidification. Besides, two intervals of palaeoceanographic perturbations were documented in the upper Tithonian–lowermost Berriasian (OD I), and the lower/upper Berriasian transition beds (OD II); these are manifested by the record of seafloor hypoxia and elevated accumulations of micronutrients, as well as changes in calcareous nannofossil assemblages. In the view of this study, the most probable trigger of the late Tithonian–early Berriasian aridization was a restriction in the atmospheric circulation (including monsoons), which was forced by climate cooling and lowering thermal gradient between landmasses and the ocean. Under such conditions, the mechanism of a wind‐induced water mixing might become less efficient, driving seawater stratification, seafloor hypoxia and increased burial of nutrients. Although the humid climate of the late Berriasian likely resumed the monsoon‐type circulation, the tectonic reactivation and uplift in the NeoTethyan Collision Belt might have effectively separated the Bakony Basin from the ‘open’ NeoTethys, which hampered the marine circulation and efficient water mixing in the former.}, year = {2024}, eissn = {1365-3091}, orcid-numbers = {Lodowski, Damian G./0000-0001-9755-1527; Szives, Ottilia/0000-0002-7279-6568; Virág, Attila/0000-0002-5530-0065; Grabowski, Jacek/0000-0001-6204-017X} } @CONFERENCE{MTMT:34788534, title = {Amphibole trace element signatures of magmatic environments within the magmatic plumbing system of the 160–30 ka Ciomadul volcanic complex, Eastern Carpathians}, url = {https://m2.mtmt.hu/api/publication/34788534}, author = {Cserép, Barbara and Erdmann, S and Haranginé Lukács, Réka and Bachmann, O and Seghedi, I and Szemerédi, Máté and Harangi, Szabolcs}, booktitle = {EGU General Assembly 2024 : abstracts}, doi = {10.5194/egusphere-egu24-19374}, unique-id = {34788534}, year = {2024}, orcid-numbers = {Haranginé Lukács, Réka/0000-0002-2338-4209; Szemerédi, Máté/0000-0002-7432-8418; Harangi, Szabolcs/0000-0003-2372-4581} } @CONFERENCE{MTMT:34788521, title = {Control of effusive and explosive eruptions of Ciomadul volcano: constraints by apatite composition}, url = {https://m2.mtmt.hu/api/publication/34788521}, author = {Hajdu, Krisztina and Haranginé Lukács, Réka and Popa, RG and Allaz, J M and Páncél, E and Cserép, Barbara and Bachmann, O and Pál-Molnár, Elemér and Seghedi, I and Harangi, Szabolcs}, booktitle = {EGU General Assembly 2024 : abstracts}, doi = {10.5194/egusphere-egu24-1116}, unique-id = {34788521}, year = {2024}, orcid-numbers = {Haranginé Lukács, Réka/0000-0002-2338-4209; Pál-Molnár, Elemér/0000-0002-9606-0133; Harangi, Szabolcs/0000-0003-2372-4581} } @CONFERENCE{MTMT:34788504, title = {Imaging the magma plumbing system of Ciomadul volcano and the Perşani Volcanic Field and constraining postcollisional magma dynamics}, url = {https://m2.mtmt.hu/api/publication/34788504}, author = {Comeau, MJ and Hill, GJ and Kovacikova, S and Kamm, J and Haranginé Lukács, Réka and Seghedi, I and Grayver, A and Bondár, István and Harangi, Szabolcs}, booktitle = {EGU General Assembly 2024 : abstracts}, doi = {10.5194/egusphere-egu24-7511}, unique-id = {34788504}, year = {2024}, orcid-numbers = {Haranginé Lukács, Réka/0000-0002-2338-4209; Bondár, István/0000-0002-4892-1074; Harangi, Szabolcs/0000-0003-2372-4581} } @article{MTMT:34765719, title = {Heavy mineral catalogue for the characterization and provenance of red sandstone macrolithic tools from Hódmezővásárhely-Gorzsa}, url = {https://m2.mtmt.hu/api/publication/34765719}, author = {Miklós, Dóra Georgina and Józsa, Sándor}, doi = {10.55023/issn.1786-271X.2024-010}, journal-iso = {ARCHEOMETRIAI MŰHELY}, journal = {ARCHEOMETRIAI MŰHELY}, volume = {21}, unique-id = {34765719}, issn = {1786-271X}, abstract = {Although ground stone tools (GSTs) are among the most abundant stone tools in archaeological sites, they are rarely investigated both from the archaeological and the geological point of view. There are many pieces made of siliciclastic sedimentary raw material. Their fragmentary condition makes it possible to examine them by slightly destructive methods, such HMA (heavy mineral analysis), which was developed primarily for siliciclastic rocks. Until now, ‘sensu stricto’ (s.str) heavy mineral analysis has not yet been carried out for ground stone tools, neither at the national nor at the international level. By comparing the heavy mineral compositions of the stone tools and their potential raw materials with the help of a newly developed HM descriptive system (including rutile, zircon, tourmaline, apatite and titanite), it is possible to determine the provenance of these archaeological materials. From the Neolithic tell of Gorzsa, 109 red sandstone macrolithic stone tools are known. These were separated into four, different types (‘Red–1’ – ‘Red–4’), based on the macroscopic and microscopic analysis. 11 fragments were chosen for HMA analysis. In addition, red-coloured sandstones from different geological occurrences of the Carpathian-Pannonian Basin (22 pieces) were also investigated. Based on the heavy mineral analysis, all raw material types of the stone tools could be originated from the Maros River and the Apuseni Mountains (Transylvania). However, the previously determined potential sources (Permotriassic and Miocene sequences from the Mecsek Mountains, Balaton Highlands, pebbles from the Danube River, and Papuk Mountains) cannot be excluded with absolute certainty from the possible raw materials.}, year = {2024}, pages = {101-118}, orcid-numbers = {Miklós, Dóra Georgina/0009-0009-1774-8510; Józsa, Sándor/0000-0001-8219-0044} } @article{MTMT:34763422, title = {HABARCSOK A KESZTHELY-FENÉKPUSZTAI KÉSŐ RÓMAI ERŐDBŐL: A PETROGRÁFIAI-GEOKÉMIAI ÉS MÉRNÖKGEOLÓGIAI VIZSGÁLATOK EREDMÉNYEI = MORTAR SAMPLES FROM THE LATE ROMAN FORTRESS OF KESZTHELYFENÉKPUSZTA: RESULTS OF PETROGRAPHIC-GEOCHEMICAL AND ENGINEERING GEOLOGICAL ANALYSES}, url = {https://m2.mtmt.hu/api/publication/34763422}, author = {Józsa, Sándor and Pintér, Farkas and Török, Ákos and Heinrich-Tamáska, Orsolya}, doi = {10.55023/issn.1786-271X.2024-014}, journal-iso = {ARCHEOMETRIAI MŰHELY}, journal = {ARCHEOMETRIAI MŰHELY}, volume = {21}, unique-id = {34763422}, issn = {1786-271X}, abstract = {The Roman fortress of Keszthely-Fenékpuszta, built in the 4th century AD, was located at the western edge of Lake Balaton on a peninsula bordered by open water and marshy peat bogs. The well-protected fortification played a significant infrastructural role, due to the fact that the lake could be crossed here along a main north-south road of Pannonia. Archaeological excavations started in 2009 had the primary goal to clarify the location, floor plan and dating of individual buildings (nos. 24, 25 and 27). Based on petrographic, geochemical, and engineering geological investigations of mortars used in the constructions, we were able to gain insight into the possibilities of answering certain archaeological questions with geoarchaeometric methods. Mortar samples were systematically collected from the different locations representing the functions and construction phases. Based on the archaeological research three chronological groups (I.-III: end of 3rd c. to early 7th c. AD) were distinguished; two of them belong to the late Roman Period (I.-II.) and one (III.) to the Migration Period. The aggregates of the mortars were analyzed by polarized light microscopy and thermoanalytical method. The chemical examination of the binder was carried out by scanning electron microscopy. Additionally, water absorption, density and compressive strength of the mortars were also determined. Based on the results, we can conclude that the mortars of all three periods are of air lime nature containing Mg and Si impurities and both the binders and additives were produced using local raw materials rich in dolomite components. The higher compressive strength values of the mortars of the 3rd period (late 5th to early 7th c. AD) are probably due to the slightly different composition of the binder, or they can also be explained by the static role of the selected pillars. © by the author(s)}, keywords = {ARCHAEOLOGY; Geochemistry; Petrography; Binder; Mortar; aggregate; Engineering geology}, year = {2024}, pages = {161-182}, orcid-numbers = {Józsa, Sándor/0000-0001-8219-0044; Török, Ákos/0000-0002-5394-4510} } @article{MTMT:34762210, title = {Raman–Infrared Spectral Correlation of an Artificially Space-Weathered Carbonaceous Chondrite Meteorite}, url = {https://m2.mtmt.hu/api/publication/34762210}, author = {Gyollai, Ildikó and Biri, Sándor and Juhász, Zoltán and Király, Csilla and Rácz, Richárd Péter and Rezes, Dániel and Sulik, Béla and Szabó, Máté Zoltán and Szalai, Zoltán and Szávai, P and Szklenár, Tamás and Kereszturi, Ákos}, doi = {10.3390/min14030288}, journal-iso = {MINERALS-BASEL}, journal = {MINERALS}, volume = {14}, unique-id = {34762210}, abstract = {Raman and infrared measurements of the same locations were conducted on a northwest African (NWA) 10580 CO3 meteorite sample, before and after three proton irradiations (1 keV ion energy using 1011, 1014, and 1017 ion/cm2 fluent values), to simulate space weathering effects. In the case of Raman spectroscopy, both FWHM and peak positions of the major olivine and pyroxene bands changed after the irradiation, and the minor bands disappeared. In the FTIR spectra, the minor bands of olivine and pyroxene also disappeared; meanwhile, major IR bands of pyroxene remained visible, demonstrating both positive and negative peak shifts, and the olivines were characterised only by negative peak shifts. The olivines were characterised by negative FWHM changes for major bands, but positive FWHM changes for minor bands. The pyroxenes were characterised by elevated FWHM changes for minor bands after the irradiation. The disappearance of minor bands both of IR and Raman spectra indicates the amorphization of minerals. The negative peak shift in IR spectra indicates Mg loss for olivine and pyroxene, in agreement with the literature. The Raman spectra are characterised by positive peak shift and positive FWHM changes; the IR spectra are characterised by a negative peak shift. The Mg loss, which was detected by negative peak shifts of FTIR bands, may be caused by distortion of the crystal structure, which could be detected by a positive peak shift in Raman spectra. This joint observation and interpretation has not been formulated in the literature, but indicates further possibilities in the confirmation of mineral changes by different instruments.
