Megjegyzések:	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.
