“…Presently, their contact is hidden under the Neogene sedimentary fill of the Danube Basin (a part of the Pannonian Basin – Great Hungarian Basin), which is located between the Eastern Alps and Western Carpathians (Figure 1). The interpretation of the Palaeogene and Neogene depositional systems in the Danube Basin confirmed the Oligocene–Early Miocene exhumation of the basin pre‐Cenozoic basement (Hók et al, 2016, 2022; Kováč et al, 2018; Šujan et al, 2021; Tari et al, 2021), and the eroded remnants from these basement units are included in the basin fill.…”

Caves are unique sedimentary archives that may record the evolution of the surrounding landscape. In this study, we applied combination of mineralogical data on allochthonous sediments with digital modelling of isobase surfaces to reconstruct the multi‐phased geomorphological development of the karst of the Harmanecká dolina Valley. The allochthonous cave sediments contain quartz and translucent heavy minerals (HMs) such as tourmaline, garnet, rutile, apatite, zircon, pyroxene, amphibole, staurolite, spinel, monazite, corundum, epidote, xenotime and florencite. Rounded shape and surface microtextures preserved on quartz and most HM grains point to predominantly a fluvial transport of detritus and its multiple recycling history. Pyroxene and amphibole are exceptions that denoted a very close source and the first‐cycle sedimentation from the adjacent volcanic Kremnické vrchy Mts. corresponding to obtained SHRIMP U–Pb detrital zircon ages of ~13.8–12.8 Ma. Heavy‐mineral geochemistry (e.g., zoned grossular‐rich garnet) and wide range of the Palaeozoic ages (Ordovician to Permian) confirms that the studied detritus sourced dominantly in the Western‐Carpathian crystalline basement rocks of the Veporic/Tatric tectonic units initially distributed by the palaeo‐Hron River and its tributaries from the east. Rare cummingtonite, remarkable tourmaline with omphacite inclusions and florencite point to the mixture of recycled sediments of Neogene Danube Basin formations containing also Austroalpine pre‐Neogene basement detritus, and confirm the original widespread distribution of the Neogene sediments currently eroded. Geomorphometric analyses of a LiDAR digital terrain model and derived isobase surface elevation models indicate the topographic development of wider area and support the findings about the transport direction of detritus. Presented multi‐method approach is suitable not only for the understanding of development of the surroundings of Harmanecká dolina Valley but also for the palaeogeographic and geomorphological reconstructions of similar karst and non‐karst areas.

“…In this study, we investigate the deformation history of the Nekézseny Thrust, a poorly exposed low-angle fault in the southernmost part of the Western Carpathians that bounds the Upper Cretaceous syn-orogenic sediments of the so-called Uppony Gosau Basin (Pelikán et al, 2005;Schréter, 1953). Similar deformed, dominantly siliciclastic successions, commonly referred to Gosau-type sediments (Hók et al, 2022;Kázmér et al, 2003;Ortner, 2001;Tari & Linzer, 2018;Wagreich, 1995;Wagreich & Faupl, 1994;Willingshofer et al, 1999), are known throughout the Alpine-Carpathian-Dinaric orogenic belt, and they may record both syn-orogenic flexural subsidence in front of emerging thrust sheets (Lužar-Oberiter et al, 2012;Matenco & Radivojević, 2012;Tari, 1995;Tari & Linzer, 2018) and/or orogen-parallel extension during the Late Cretaceous to Paleogene (Fügenschuh et al, 2000;Krohe, 1987;Madarás et al, 1996;Neubauer et al, 1995;Plašienka & Soták, 2015;Ratschbacher et al, 1989;Wagreich & Decker, 2001). Here, we combine detailed structural analysis with multi-method thermochronology to overcome the challenges resulting from the poor outcrop conditions and large sedimentary hiatuses.…”

Unraveling the age and kinematics of low temperature deformation events is crucial in understanding the late‐stage evolution of orogens. 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.
