Abstract:The tectonic evolution of the pre-Cenozoic basement, as well as the Cenozoic structures within the Danube Basin (DB) and its northern periphery are presented. The lowermost portion of the pre-Cenozoic basement is formed by the Tatricum Unit which was tectonically affected by the subduction of the Vahicum / Penninicum distal continental crust during the Turonian. Tectonically disintegrated Tatricum overlaid the post-Turonian to Lower Eocene sediments that are considered a part of the Vahicum wedge-top basin. These sediments are overthrust with the Fatricum and Hronicum cover nappes. The Danube Basin Transversal Fault (DBTF) oriented along a NW-SE course divided the pre-Neogene basement of the DB into two parts. The southwestern part of the DB pre-Neogene basement is eroded to the crystalline complexes while the Palaeogene and Mesozoic sediments are overlaid by the Neogene deposits on the northeastern side of the DBTF. The DBTF was activated as a dextral fault during the Late Oligocene -Earliest Miocene. During the Early Miocene (Karpatian -Early Badenian) it was active as a normal fault. In the Middle -Late Miocene the dominant tectonic regime with NW -SE oriented extension led to the disintegration of the elevated pre-Neogene basement under the simple and pure shear mechanisms into several NE -SW oriented horst and graben structures with successive subsidence generally from west to east. The extensional tectonics with the perpendicular NE -SW orientation of the S hmin persists in the Danube Basin from the ?Middle Pleistocene to the present.

“…The Rožňava Fault as well as the Darnó Zone show similar orientations to the main extension oriented in a NNE-SSW to NE-SW direction during the Late Miocene (Mello et al, 1996;Petrik et al, 2016). Orientation of the stress field extension component (Littva et al, 2015) yielded a NE-SW striking extension most probably during the Pliocene-Early Pleistocene, and a younger (Late Pleistocene-Holocene) WNW-ESE striking extension. Two caves were selected in the eastern part of the Slovenský kras Mts., close to a significant geomorphological contact with the Košická kotlina Basin ( Fig.…”

The fault displacement monitoring network EU-TecNet was established to define microdisplacements across faults in the territory of Central Europe (www.tecnet.cz) using threedimensional optical-mechanical extensometers. The results of long-term neotectonic activity obtained from two caves localized in the eastern part of the Slovenský kras Mts. (SE Slovakia) show generally NE-SW oriented dilatation. This orientation is in a good accordance with the orogen-parallel extension monitored in the Western Carpathians. Differing short-lasting trends were distinguished in 2011-2012 and 2013-2015, which supports the significance of the tectonic pulse at the end of 2012 and the beginning of 2013. Moreover, simultaneous short-lasting faulting occurred at both sites under the transtensional tectonic regime, where the principal maximum compressional axis operated in a NW-SE direction (σ 1). The observed results were compared to data from monitoring points in distant areas of the European plate.

“…The morphotectonic analyses reveal that the depression located SE of Bešeňová consists of several partial blocks. This could suggest the local hierarchical neotectonic structure of the mentioned part of the LKB resulting from a changed stress field (Pešková andLittva et al 2015).…”

Morphotectonic analysis for improvement of neotectonic subdivision of the Liptovská kotlina Basin (Western Carpathians)The Liptovská kotlina Basin (LKB) belongs to the most neotectonically active intramountain basins of the Western Carpathians (Halouzka 1993). Its last neotectonic subdivision was carried out at the scale ~ 1:200,000 (Halouzka 1993), later included in the Neotectonic map of Slovakia . This paper presents a more detailed subdivision and delineation of borders of neotectonic blocks of the LKB on the basis of the set of morphotectonic analyses. The Váh River terraces, thickness of Quaternary deposits, faults and morpholineaments and SL index were employed to more precisely delimitate the neotectonic blocks. A long profile analysis of the river terraces bedrock (inferred from 127 drillings and outcrops) and bedrock surface of the recent floodplain (65 drillings) was carried out to detect neotectonic faults within the fluvial systems. Based on the relative height of the surfaces under a terrace and previous fluvial sediment investigations (e.g. Droppa 1964 andGross 1979), eleven terrace levels were confirmed. 1,958 boreholes and 1,085 geophysical points were used to identify the spatial distribution of the thickness of the Quaternary fill of the basin. Tectonic faults and morpholineaments were used as borders of particular neotectonic blocks. Suggesting the alternation of neotectonic borders, the LKB was subdivided into 60 neotectonic blocks comparing to 24 blocks of former subdivisions . Moreover, a new Quaternary depression filled with glacifluvial deposits was identified (min 50 m of thickness) in close vicinity to Pribylina, which could be added to the depressions list (Maglay et al. 2011a).
