In this study, we combined detrital zircon U–Pb geochronology with compositional, mineralogical, and morphological data from four bauxite locations in the NDPGB to provide a new palaeogeographical and palaeoenvironmental evolution model for the Lutetian–Rupelian timeframe of the NDPGB. The Eocene climatic conditions began with the Palaeocene–Eocene Thermal Maximum event (∼56 Ma), followed by the Early Eocene Climatic Optimum (∼49 Ma) and Middle Eocene Climatic Optimum (∼40 Ma), and were completed as a cooling trend culminating around the Eocene/Oligocene boundary (∼34 Ma), with a shift towards an icehouse climate. These events were coeval with the continuous drift of the African continent towards Eurasia and the subsequent closure of the western part of the former Neo-Tethys Ocean associated with massive volcanic activity. Based on the bauxite deposits of the NDPGB, Early Eocene limestones formed in the last phase of the long-lasting Adriatic Carbonate Platform. The Middle Eocene orogenic activity resulted in an elevation in this area. High average temperatures, accelerated hydrological cycles and precipitation, and intensive continental weathering with increased volcanic carbon input resulted in favourable conditions for the development of karst bauxites at this time. Further Upper Eocene tectonic deformation of the NDPGB area resulted in the development of bauxite traps and enabled redeposition of the initial bauxite material. Subsequently, the bauxite deposits were covered with clastic carbonate molasse derived from the intensive erosion of the young Dinaric orogeny. The implications of this study are as follows. First, it provides new information on the timing of bauxitisation in the area by providing the first radiometric zircon geochronology, which refined and restricted the time window for bauxite formation in this region. Additionally, our results provide a new perspective on the possibility of aeolian precursors in karst bauxite formation and provide new constraints on the first tectonic marks of the initial Dinaric orogeny.}, year = {2023}, eissn = {2296-6463}, orcid-numbers = {Mindszenty, Andrea/0000-0001-8927-3053} } @{MTMT:34016157, title = {Budapest földtani öröksége dióhéjban}, url = {https://m2.mtmt.hu/api/publication/34016157}, author = {Mindszenty, Andrea}, booktitle = {Budapest 150}, unique-id = {34016157}, year = {2023}, pages = {33-51}, orcid-numbers = {Mindszenty, Andrea/0000-0001-8927-3053} } @article{MTMT:33126810, title = {Origin, timing and paleogeographic implications of Paleogene karst bauxites in the northern Transdanubian range, Hungary}, url = {https://m2.mtmt.hu/api/publication/33126810}, author = {Kelemen, Péter and Dunkl, István and Csillag, Gábor and Mindszenty, Andrea and Józsa, Sándor and Fodor, László and von Eynatten, Hilmar}, doi = {10.1007/s00531-022-02249-3}, journal-iso = {INT J EARTH SCI}, journal = {INTERNATIONAL JOURNAL OF EARTH SCIENCES}, volume = {112}, unique-id = {33126810}, issn = {1437-3254}, abstract = {Paleogene karst bauxites in the northeastern Transdanubian Range and their cover sequences provide valuable sedimentary archives, despite their weathered nature and vague paleontological records. U–Pb detrital zircon geochronology combined with heavy mineral analysis indicates ‘local’ Alpine aeolian and fluvial sources and ‘distant’ aeolian sources connected to the Bohemian Massif. Records of episodic Paleogene volcanic eruptions related to igneous complexes of the Adamello and probably also the Bergell, Recsk and Balkan Peninsula, are reflected by euhedral zircon crystals. Their U–Pb geochronology supplies age constraints for the phases of subaerial exposure of the karstic surface and the accumulation of bauxitic protoliths and helps to improve the existing stratigraphic records and to define stages of denudation in the northeastern Transdanubian Range. Distinct phases of subaerial exposure and accumulation of the bauxite's protoliths are identified as ca. 42, 35 and 31 Ma; alternating with episodes of subsidence, represented by siliciclastic and carbonatic sequences at ca. 38, 32 and 31 Ma. Besides Paleogene volcanism, zircon dating also revealed contributions from the Middle Triassic tuffs of the Transdanubian Range. Garnet, epidote, kyanite, staurolite, and xenotime/monazite crystals suggest fluvial drainage of diverse metamorphic units of the Austroalpine basement from the Eastern- and Southern Alps, which also supplied most of the pre-Mesozoic zircons. However, the unexpectedly high proportion of Variscan ages in the bauxites most likely relate to igneous rocks of the Bohemian Massif, thus suggesting additional long-distance aeolian sources. The new data allow for detailed reconstructions of the Paleogene evolution and palaeogeography of the northeastern Transdanubian range.}, year = {2023}, eissn = {1437-3262}, pages = {243-264}, orcid-numbers = {Mindszenty, Andrea/0000-0001-8927-3053; Józsa, Sándor/0000-0001-8219-0044} } @{MTMT:33043389, title = {Paleokarst in Hungary}, url = {https://m2.mtmt.hu/api/publication/33043389}, author = {Mindszenty, Andrea and Sebe, Krisztina}, booktitle = {Cave and karst systems of Hungary}, doi = {10.1007/978-3-030-92960-2_5}, unique-id = {33043389}, year = {2022}, pages = {117-136}, orcid-numbers = {Mindszenty, Andrea/0000-0001-8927-3053; Sebe, Krisztina/0000-0002-4647-2199} } @article{MTMT:32152165, title = {A new diverse charophyte flora and biozonation of the Eocene bauxite cover-sequence at Gant (Vertes Hills, Hungary)}, url = {https://m2.mtmt.hu/api/publication/32152165}, author = {Trabelsi, Khaled and Sames, Benjamin and Wagreich, Michael and Kázmér, Miklós and Mindszenty, Andrea and Martin-Closas, Carles}, doi = {10.1080/14772019.2021.1938264}, journal-iso = {J SYST PALAEONTOL}, journal = {JOURNAL OF SYSTEMATIC PALAEONTOLOGY}, volume = {19}, unique-id = {32152165}, issn = {1477-2019}, abstract = {A diverse Eocene charophyte flora from a section at Gant (Vertes Hills), Transdanubian Central Range, north-western Hungary, provides significant new information building on previous studies based only on sub-surface data published from the mid-twentieth century. This newly acquired material facilitates the taxonomic revision and emendation of the species Raskyella peckii and thereby defines a new anagenetic lineage based on three successive varieties that were formerly considered as separate species or subspecies: Raskyella peckii var. peckii (early Lutetian-early Bartonian), Raskyella peckii var. caliciformis (early Bartonian), and Raskyella peckii var. vadaszii (late Bartonian). Based on this lineage, we propose a new local charophyte biozonation that consists of a 'Raskyella peckii Superzone' (Lutetian-Bartonian), sub-divided into three successive charophyte partial range zones: the 'Raskyella peckii peckii Zone' (Lutetian-lower-most Bartonian) characterized by an assemblage of R. peckii peckii, Gyrogona caelata forma caelata, G. caelata forma monolifera and Nitellopsis (Tectochara) aff. palaeohungarica, the 'Raskyella peckii caliciformis Zone' (lower Bartonian) characterized by the assemblage of R. peckii var. caliciformis, G. caelata forma caelata, G. caelata forma monolifera, G. caelata forma baccata, Nitellopsis (Tectochara) aff. palaeohungarica and Chara media, and the 'Raskyella peckii vadaszii Zone' (upper Bartonian) characterized by R. peckii var. vadaszii, G. caelata forma bicincta, G. caelata forma baccata, G. caelata forma fasciata, G. tuberosa, Psilochara polita, Psilochara sp., Chara media and Chara subcylindrica. Future research may show the new local biozonation as applicable to the whole of Europe and complementary to the current European charophyte biozonation. Our results show that the sequences from Gant, which were previously regarded as upper mid-Eocene (upper Lutetian-lower Bartonian) in age, appear to represent a longer chronostratigraphic interval: lower Lutetian to upper Bartonian. Our chronostratigraphic results imply a longer and more stepwise Eocene major transgression in the Transdanubian Central Range than previously thought.}, keywords = {Central Europe; Paleogene; Characeae; Raskyellaceae; phylozone; gradualistic evolution}, year = {2021}, eissn = {1478-0941}, pages = {541-563}, orcid-numbers = {Kázmér, Miklós/0000-0003-1092-1316; Mindszenty, Andrea/0000-0001-8927-3053} } @CONFERENCE{MTMT:31996201, title = {Charophyte biostratigraphy of continental deposits in a filled-karst system: A case study from the Eocene bauxite cover-sequence at Gánt (Vértes Hills, Hungary)}, url = {https://m2.mtmt.hu/api/publication/31996201}, author = {Khaled, Trabelsi and Benjamin, Sames and Michael, Wagreich and Kázmér, Miklós and Mindszenty, Andrea and Carles, Martín-Closas Martín-Closas}, booktitle = {EGU General Assembly 2021: Conference Abstracts}, unique-id = {31996201}, year = {2021}, orcid-numbers = {Kázmér, Miklós/0000-0003-1092-1316; Mindszenty, Andrea/0000-0001-8927-3053} } @article{MTMT:31931179, title = {Id.
