Paleostress reconstruction of faults recorded in the Niedźwiedzia Cave (Sudetes): insights into Alpine intraplate tectonic of NE Bohemian Massif

Abstract: Brittle structures identified within the largest karstic cave of the Sudetes (the Niedźwiedzia Cave) were studied to reconstruct the paleostress driving post-Variscan tectonic activity in the NE Bohemian Massif. Individual fault population datasets, including local strike and dip of fault planes, striations, and Riedel shear, enabled us to discuss the orientation of the principal stresses tensor. The (meso) fault-slip data analysis performed both with Dihedra and an inverse method revealed two possible main op… Show more

“…During the Late Cretaceous, recurrent marine transgressions resulted in the formation of a >3 km thick sedimentary cover, subsequently removed during the Late Cretaceous-Cenozoic tectonic exhumation [13]. Late Cretaceous-Cenozoic tectonic activity resulted in bedrock jointing and faulting under compressional WNW-ESE conditions [14]. During the Paleogene, after the tectonic movements ceased, a regional peneplaine evolved, characterised by a generally flat and hilly landscape.…”

“…During the Neogene (Late Miocene-Pliocene? ), active fault-block movements in the eastern part of the Śnieżnik Massif associated most-likely with WNW-ESE compressional regime (Sobczyk & Szczygieł, 2021) resulted in fluvial erosional cutting through strongly folded marbles of the Stronie formation and water-table cave formation. For the Quaternary (Pleistocene?)…”

“…Importantly, recent GNSS measurements combined with geological, geomorphological and geophysical data show significant, mainly dextral movements along the SMF (Roštínský et al, 2020). Within a range of 30-40 km from Niedźwiedzia Cave, one of the most seismically active structures is the Hronov-Pořiči Fault Zone (Sobczyk & Szczygieł, 2021), the easternmost part of the important central European tectonic structure-the Elbe Fault system (Málek et al, 2008). The Elbe Fault system contains mostly dextral NW-SE and NNW-SSEstriking faults and is suspected to be responsible for the most intense historical earthquakes in the NE Bohemian Massif (Špaček et al, 2006).…”

“…The cave was formed within the marbles dated from Middle Cambrian to Early Ordovician (520–470 Ma) 2 . Their karstification began after the Paleogene basin inversion climax (65–45 Ma) 3 before its final post-Mid-Miocene uplift 4 . The karstification process in Kleśnica Valley aligned with WSW–ENE trending sub-vertical faults and fractures, with N–S to NNW–SSE steeply dipping foliation playing a subordinate role 5 .…”
