Similarly oriented magnetic lineation is also documented in some Huty Fm. sites. Magnetic and structural results reveal the dip of the post-trusting Paleogene strata covering the Chočské vrchy Mts. horst block differs from both the dip of magnetic lineation and the dip of statistical fold axis from the Krížna nappe within this uplifted block, suggesting complex uplift-related deformations. We conclude that Krížna nappe folds together with AMS lineation, both formed during Late Cretaceous thrusting, have been later rotated by an angle of 20° as an effect of Neogene transpression, which also affected the magnetic fabric of the post-thrusting cover. © 2022 Sciendo.

The calculations indicate that seismic waves can be amplified up to 10 times and the expected resonance frequency is ~17.05 Hz. We argue that the observed SSDS formed in two stages. First, brittle and ductile deformation structures developed due to gravity-induced slumping. Next, liquefaction produced water-escape structures. The studied SSDS were likely seismically triggered. Favorable conditions occurred during the withdrawal of the last glacier (MIS 2) when the sediments were oversaturated and the Tatra Mts. experienced a strong earthquake (M7.0). Alternatively, high-frequency microearthquakes could have been triggered by slope failure cutting into Kalacka Cave. © 2020 Elsevier Ltd

abstract = {Detailed structural analysis and geomorphological observations supplemented by the analysis of the distribution of karst conduit directions have been performed in 23 morphologically diverse caves in the Tatra Mountains. Based on these studies, a development scheme of vadose cave passages has been proposed for the most common geological settings in the fold-and-thrust-belt: (1) single-plain faults, (2) multiple fault cores, (3) bedding plane fractures and (4) hinge zones of recumbent folds. Results indicate that the dynamics of the massif (local gravity sliding in the nearby slope zone and regional stress fields), along with the structural pattern, influences the predisposition of structural and stratigraphic discontinuities to karst drainage. Constant tectonic stress fields affected the massif during the entire speleogenesis.

Detailed structural analysis and geomorphological observations supplemented by the analysis of the distribution of karst conduit directions have been performed in 23 morphologically diverse caves in the Tatra Mountains. Based on these studies, a development scheme of vadose cave passages has been proposed for the most common geological settings in the fold-and-thrust-belt: (1) single-plain faults, (2) multiple fault cores, (3) bedding plane fractures and (4) hinge zones of recumbent folds. Results indicate that the dynamics of the massif (local gravity sliding in the nearby slope zone and regional stress fields), along with the structural pattern, influences the predisposition of structural and stratigraphic discontinuities to karst drainage.
