However, accurate age constraints can often be challenging to obtain due to unideal outcrop conditions, large sedimentary hiatuses or the lack of well‐defined thermal events. In this study, we show on the example of the Nekézseny Thrust, a poorly exposed late orogenic thrust in the southern Western Carpathians, that a combined approach of structural analysis and multi‐method thermochronology can provide the necessary temporal, kinematic and thermal constraints for a detailed reconstruction of the deformation history. While structural mapping revealed that the Late Cretaceous Uppony Gosau Basin in the footwall of the Nekézseny Thrust underwent a significant post‐Campanian and pre‐Miocene shortening, K/Ar dating of fault gouge samples from the main fault zone constrained the primary thrusting event to the Maastrichtian. Based on the acquired apatite fission‐track and (U‐Th)/He ages, subsequent heating of the Upper Cretaceous sediments due to tectonic burial was limited to 75–100°C, followed by deformation‐related and gradual cooling between the Eocene and Early Miocene. Considering the reconstructed deformation history, as well as the large‐scale tectonic affinity of the displaced units in its footwall and hanging wall, the Nekézseny Thrust is a far‐traveled (ca. 600 km) segment of the Late Cretaceous Alps‐Dinarides contact zone, whose development was linked to the switch from lower plate to upper plate position with respect to the Sava Zone and Alpine Tethys sutures, respectively.}, year = {2024}, eissn = {1944-9194}, orcid-numbers = {Kövér, Szilvia/0000-0002-6736-4226; Németh, Tibor/0000-0002-1836-6006} } @misc{MTMT:34547407, title = {Contrasting surface evolution during structural inversion of rifted basins: 3D coupled geodynamical and surface processes models}, url = {https://m2.mtmt.hu/api/publication/34547407}, author = {Oravecz, Éva and Balázs, Attila and Gerya, T and Fodor, László}, unique-id = {34547407}, year = {2023}, orcid-numbers = {Balázs, Attila/0000-0003-2948-0397} } @misc{MTMT:34541072, title = {Intra-oceanic subduction initiation or rifted margin reactivation?

In this study, we explain several diagnostic structural and sedimentary features that may be used to distinguish pre‐orogenic halokinetic structures from shortening‐related structures on the example of the Silica Nappe (Inner Western Carpathians, Central Europe). Detailed structural mapping in this area resulted in the recognition of several pre‐orogenic salt‐related structures, including linear salt walls and minibasins. Initial evaporite movement started as early as the late Early Triassic, and widespread diapirism occurred during the Middle to Late Triassic, ultimately leading to facies differentiation, with carbonate platform growth in the subsiding minibasins and reduced basinal deposition on top of the diapirs. Later, the inherited salt structures localized the deformation during the Cretaceous Alpine orogeny, and exerted a strong control on the geometry and kinematics of the subsequent deformations. Our new interpretation explains previously unsolved structural problems in the Silica Nappe, like pre‐orogenic thickness variations during the post‐rift phase, frequent young‐on‐older type thrust contacts and multiple folding directions with variable vergencies. The results point out that the Silica Nappe is a fold‐and‐thrust belt, where pre‐orogenic salt tectonics and its effects on the fold‐and‐thrust belt evolution can be studied in detail.}, year = {2023}, eissn = {1944-9194}, orcid-numbers = {Oravecz, Éva/0000-0003-1032-1564} } @CONFERENCE{MTMT:33830571, title = {Competing effects of post-rift thermal subsidence and contraction-induced tectonic uplift in inverted extensional basins: inferences from numerical models and observations from the Pannonian Basin}, url = {https://m2.mtmt.hu/api/publication/33830571}, author = {Oravecz, Éva and Balázs, Attila and Taras, Gerya and Dave, May and Fodor, László}, booktitle = {EGU General Assembly 2023: Abstracts}, doi = {10.5194/egusphere-egu23-671}, unique-id = {33830571}, year = {2023} } @CONFERENCE{MTMT:33830548, title = {Illite K/Ar dating of fault zones, sedimentary sequences and low-grade metamorphic rocks}, url = {https://m2.mtmt.hu/api/publication/33830548}, author = {Benkó, Zsolt and Oravecz, Éva and Fodor, László and Kövér, Szilvia and Obbágy, Gabriella and Németh, Tibor and Kovács, Ivett and Máthé, Zoltán and Arató, Róbert and Molnár, Kata and Maros, Gyula}, booktitle = {19th meeting of the Central European Tectonic Studies Group (CETeG)}, unique-id = {33830548}, year = {2023}, pages = {7-8}, orcid-numbers = {Kövér, Szilvia/0000-0002-6736-4226; Németh, Tibor/0000-0002-1836-6006; Kovács, Ivett/0000-0001-7015-7909; Molnár, Kata/0000-0001-6993-5806; Maros, Gyula/0000-0002-2973-4513} } @CONFERENCE{MTMT:33830526, title = {Vertical motion patterns in inverted sedimentary basins: competing effects of contraction-induced tectonic uplift, post-rift thermal subsidence and surface processes}, url = {https://m2.mtmt.hu/api/publication/33830526}, author = {Oravecz, Éva and Balázs, Attila and Taras, Gerya and Dave, May and Fodor, László}, booktitle = {19th meeting of the Central European Tectonic Studies Group (CETeG)}, unique-id = {33830526}, year = {2023}, pages = {72} } @CONFERENCE{MTMT:33806220, title = {Structural inversion of rotational and oblique sedimentary basins: inferences from 3D coupled thermo-mechanical and surface processes models}, url = {https://m2.mtmt.hu/api/publication/33806220}, author = {Oravecz, Éva and Balázs, A. and Gerya, T. and May, D. and Fodor, László}, booktitle = {AGU Fall Meeting 2022}, unique-id = {33806220}, year = {2022}, pages = {1} }
