“…This allowed to obtain a representative sample and the measured dip azimuth as well as to determine the directions of main crack systems occurring in the studied rock mass. In order to illustrate the subsurface structures of rock, the electrical resistivity tomography (ERT) was used as a non-destructive and non-invasive method of measurement (Schrott and Sass 2008;Akca 2016;Amini and Ramazi 2016;Kowalczyk et al 2017;Szczygieł et al 2019). The measurements were taken with the ABEM Terrameter LUND Imaging System applying the Wenner-Schlumberger array.…”

In the area of the Skalni Potok Nature Reserve (Hrubý Jesenik), studies of gneissic cliffs were carried out to determine the role of lithology in the process of their formation. The research included geometric measurements of vertical discontinuity zones of selected rock outcrops and the electrical resistivity tomography (ERT) measurements of strongly weathered subsurface layers. As a result of the measurement, the orientation of the main crack systems (NW-SE and NE-SW) responsible for the location of cliffs within the Skalni Potok Valley was obtained. In addition, the main crack directions for the gneiss occurring in the studied mountain region were identified. Interpretation of the ERT models allowed to characterise the structure of the rock mass, including the reach of the rainwater infiltration level and the depth of the weathering front.

“…5), but the local caves show formation of speleothems at that time. If mountain glaciers did exist in the Carpathians, they must have been short-lived and of limited extent (Szczygieł et al, 2019;Błaszczyk et al, 2020). Speleothems formed contemporaneously in the Alps (Spötl & Mangini, 2007), where recognizable significant cooling occurred at the closure of MIS 8 (ca 240 to 230 ka), indicating short-lived glaciers.…”

This case study from the renowned Demänová Cave System in the Carpathians of Slovakia demonstrates that the conventional methods of fluvial sedimentology, combined with an allostratigraphic mapping and speleothem Useries isotopic dating, can give unprecedented insights into the hydrological history of underground karst conduit. The deposits studied are a relic compound sidebar ranging from gravel to mud and encapsulating the conduit's hydrological history from the middle Pleistocene to the present time. A succession of 10 allostratigraphic units, time-constrained by speleothems, are recognized in the sidebar deposits, and the corresponding morphodynamics of an evolving cave-floor sedimentation are reconstructed in considerable detail. The subterranean river water stages recognized from the deposits, time-constrained by flowstone layers and stalagmites, correlate with and add to the regional record of climate changes. Two distinct episodes of flow ponding (high-stage slackwater conditions) are recognized and attributed to the independently documented downstream cave-roof collapses, probably triggered by the Carpathian post-orogenic earthquakes. This multidisciplinary study may serve as a useful methodological guide for the analysis of fluviokarstic deposits in speleological research and reconstruction of their hosting cave hydrological history.

“…Wet-based mountain glaciers are documented to be efficient agents of erosion (Stern et al, 2005) that commonly create dramatic, high-relief landscapes. Indeed, mountain glaciers have been invoked as both limiting and amplifying relief creation (e.g., Brozović et al [1997] versus Molnar and England [1990]) as well as exhumation (Stern et al, 2005;Thomson et al, 2010;Meyer et al, 2011). Yet the cyclic variation between hothouse and icehouse conditions during the Quaternary makes deciphering the magnitude of erosion attributable to any single glacial episode difficult to quantify.…”

Wet-based mountain glaciers are efficient agents of erosion, which leads to the assumption that each glacial episode results in successive valley deepening. The tendency of subsequent glaciations to obscure evidence of previous events makes it difficult to study the work done by past glacial episodes. Epiphreatic and paleophreatic caves that developed at or under the water table and dried out in response to valley deepening can serve as recorders of the valley incision history. U-series data from speleothems in the cave networks at the base of the present-day valleys in the Tatra Mountains (Western Carpathians) consistently yield the oldest ages of ca. 325 ka. While speleothem ages are typically phreatic-vadose transition minimum ages, they nonetheless unequivocally demonstrate that neither glacial valley deepening nor fluvial incision occurred over the past 300 ka, unlike the successive valley deepening over the same period in the adjacent Alps.
