The Meliata Unit (Meliaticum) is a remnant of the Tethyan oceanic suture occurring in the southern Western Carpathian zones. It includes the blueschist-facies Bôrka Nappe and low-grade syn-orogenic accretionary complexes, which are generally assigned to the Meliata Unit s.s. The Meliatic chaotic tectono-sedimentary units related to the closure of t...

As a crucial segment of the geological structure of the Western Carpathians, the Meliata Superunit represents a remnant after the Meliata Ocean's closure. Its composition is defined by the blueschist-facies Bôrka Nappe, the low-grade Jurassic sedimentary complex with olistostromes that constitute the Meliata Unit s.s., and a polygenous mélange that...

The paper summarizes the basic Slovak terminology of the fold and thrust belts and proposes the usage and form of some new terms. In the introductory part, the term fold and thrust belts itself, and its usage in foreign literature is discussed, with original English texts quoted. The second part of the article contains a short glossary of terms wit...

Volcanic rocks in the Pieniny Klippen Belt (PKB) of the Western Carpathians have been the focus of geologists for over a century (e.g. Uhlig, 1890; Małkowski, 1921). Miocene volcanism is most common in the PKB. However, there are infrequent occurrences of Cretaceous volcanic rocks. Several magmatic bodies of Cretaceous age have already been desc...

The Polish-Slovak Pieniny Mountains are the traditional area where ideas about the age of sedimentary formations and tectonics of a peculiar Western Carpathian regional structure-the Pieniny Klippen Belt (PKB)-have been developing for nearly two centuries. However, due to the extraordinary complicated tectonic situation, opinions concerning the str...

Provenance study of the Upper Cretaceous – Paleocene turbiditic deposits of the Pupov Formation with uncertain tectonic affiliation exposed in the Varín sector of the Pieniny Klippen Belt is presented. Petrographic and heavy mineral analyses including geochemistry of detrital Cr-spinels, tourmalines and garnets were carried out. The studied deposit...

The Meliata Unit (Meliaticum) is a tectonic superunit of the Western Carpathians that incorporates the blueschists-facies Bôrka Nappe and the low-grade metasediments and polygenetic mélange, Meliata Unit s.s., both occurring as scattered tectonic slices overlying the Gemeric Superunit. Calcitic marbles were sampled in a wide area within the Bôrka N...

The Oravicum provides a crustal ribbon, whose deposits recently form a major part of the Pieniny Klippen Belt being a mélange zone between the Carpathian internides and externides. The Hauterivian-Albian turnover completely changed its character. The paper brings synthesis of old and new data that reveals processes which had taken place at that tim...

The Pieniny Klippen Belt of the Western Carpathians is a peculiar tectonic and geomorphological zone that is only a few km wide, but up to 600 km long. It separates the External Western Carpathians from the Central Western Carpathians. The Pieniny Klippen Belt is exceptional by its picturesque rugged landscape, being formed by numerous, and often i...

The territory of Slovakia is located in Central Europe and is built up by the Western Carpathian mountain range to the north and the overstepping Cenozoic Basin system in the central and southern parts. The Western Carpathians are an integral part of the northern branch of the Carpathian arc and the whole European Alpine orogenic system, which was...

Occurrences of magmatic rocks were identified north of the settlement Belanskovci (part of Myjava town), on the ridge of the elevation point 464 m a. s. l. east of the settlement Podzámok (part of the Podbranč village). The volcanic rock sample was petrographically studied under the polarizing microscope, BSE and EDAX analyses. Based on these, the...

The investigated area represents a segment of the contiguous Veporic–Gemeric zone characterized by the presence of several major superposed and/or juxtaposed tectonic units, exhibiting contrasting structural and metamorphic histories. Based on the structural, petrological and geochronological (EMPA dating of monazites) investigations, the principal...

To track the evolution and formation of one of the major sub-basins of the Pannonian back-arc basin system, we re-evaluate pre-rift, syn-rift, post-rift, and inversion stages of the Danube Basin. This synthesis builds upon a new compilation of (i) geophysical measurements, (ii) current data about the substratum of the basin, (iii) recent advances i...

The Cretaceous basement of the broader NW Pannonian Basin, including the Vienna Basin, has an Alpine nappe structure that can be correlated between the Eastern Alps and the Western Carpathians. For the first time in this region, based on the systematic integration of petroleum industry vintage 2D reflection seismic data with well data from Austria,...

The thin skinned Hronic nappe system represents the structurally highest tectonic unit in the Late Cretaceous thrust-stack of the Central Western Carpathians. It mostly comprises a Permian volcano-sedimentary sequence and Triassic carbonate sediments which crop out in different parts of the Central Western Carpathians. We carried out a systematic p...

The Pieniny Klippen Belt (PKB) and adjoining zones form a narrow, but lengthy belt that separates the Cretaceous nappe stack of the Central (Austroalpine) and the Cenozoic accretionary wedge of the External Western Carpathians (Flysch Belt). The PKB shares units and structures of both, in addition to the distinctive Oravic units, derived from a con...

Based on macrostructural, microstructural and CPO characteristics the group G3 records deformation in the vicinity of the Veporic unit in the west. Group G1 represent typical occurrences of Bôrka Nappe in the eastern part of study area and samples of group G2 are transitional member between east and west occurrences.

The paper deals with the structure and evolution of the Pieniny Klippen Belt in its classic area in western Slovakia. The so-called Peri-Klippen Zone provides a transition from the Pieniny Klippen Belt s.s. built up by Jurassic to Eocene Oravic units (Šariš, Subpieniny and Pieniny from bottom to top) to the outer margin of the Central Western Carpa...

The Pieniny Klippen Belt contains thickening and coarsening upwards synorogenic sedimentary successions witnessing the collision of the Oravic ribbon continent with the Central Carpathian orogenic wedge after the closure of the Vahic Ocean in the Late Cretaceous to Early Palaeogene. The sedimentary record of this event is represented by flysch/wild...

This paper presents geochemical data on sedimentary rocks from the Upper Cretaceous to Lower Eocene formations of the Pieniny Klippen Belt (Western Carpathians, Slovakia). On the basis of geochemical analyses of 15 samples, the plate tectonic setting of sediment accumulation and paleodepositional environment were reconstructed, which may help to un...

This study is focused on the westernmost occurrence of the Pieniny Klippen Belt (PKB) between village Podbranč and Myjava town. Near Podbranč, the PKB emerges from the substratum of the Neogene Vienna Basin and then spreads for some 600 km further eastward as a narrow, extremely complicated zone that separates the Cretaceous basement cover nappe st...

The Western Carpathian Meliata Superunit (Meliaticum) includes a heterogeneous group of units—the blueschist-facies Bôrka Nappe and the very low-grade chaotic complexes—polygenous mélange containing material derived from various tectonic settings (Jaklovce Unit) and Jurassic oceanic sediments with olistostrome bodies (Meliata Unit s.s.). The high p...

Based on the literature examinations and field investigations in various parts of the Pieniny Klippen Belt of the Western Carpathians, a tentative classification of the klippen forms and types is presented. The mode of the klippen separation (genetic aspect), inclination of klippen long axes (structural factor), and alterations impressed by superim...

The Manín Unit represents a transitional tectonic element between the Central Western Carpathians and the Pieniny Klippen Belt. The overall map-view structure of the Manín Unit is dominated by elliptical antiforms composed of comparatively competent Jurassic and Lower Cretaceous strata, surrounded by soft Upper Cretaceous shales, marls and sandston...

Key Points Limited Cenozoic shortening of the Western Carpathians facilitates a comprehensive tectonic model of their pre‐Late Eocene evolution Western Carpathian orogeny was driven by pull of the Meliata oceanic slab and by the northward drift of Adria Multiple rock record data provide valuable constraints for evolutionary tectonic models of colli...

Infratatic evolutionary model

The Inner Western Carpathians (IWC) orogenic wedge formed in the course of progressive closure of the Meliata(-Hallstatt) and the Penninic oceanic basins and related subduction-collision processes (e.g., Kozur 1991, Putiš 1991, Neubauer 1994, Faryad 1995, Plašienka et al. 1997, Schmid et al. 2008). This study targets the frontal IWC Infratatric Uni...

In summary, our results demonstrate that: (1) based on the structural and metamorphic criteria and in line with the earlier views of Klinec (1966, 1971), the Early Paleozoic age of HDC is favoured; (2) only Permian age of the Veporic post-Variscan cover in the investigated area is proposed; (3) the pervasive low-grade Alpine metamorphic foliation i...

This paper presents geochronological data for the volcanic dykes located in the northern Považský Inovec Mts. The dykes are up to 5 m thick and tens to hundreds of metres long. They comprise variously inclined and oriented lenses, composed of strongly altered grey-green alkali basalts. Their age was variously interpreted and discussed in the past....

The Súľov Conglomerates represent mass-transport deposits of the Súľov-Domaniža Basin. Their lithosomes are intercalated by claystones of late Thanetian (Zones P3-P4), early Ypresian (Zones P5-E2) and late Ypresian to early Lutetian (Zones E5-E9) age. Claystone interbeds contain rich planktonic and agglutinated microfauna, implying deep-water envir...

The data on the Neogene geodynamics, palaeogeography, and basin evolution of the Western Carpathians, Northern Pannonian domain and adjoining areas (ALCAPA Mega-unit) are summarized, re-evaluated, supplemented, and newly interpreted. The proposed concept is illustrated by a series of palinspastic and palaeotopographic maps. The Miocene development...

The protracting debate about the position and tectonic affiliation of the Upper Jurassic to Upper Cretaceous sediments occurring in the Považský Inovec Mts has got a revived impulse by a new interpretation presented in the recent paper of Pelech et al. (2016). We discuss several aspects of their alternative explanation which considers the wedge-top...

The Middle Carnian (Julian) detritic sediments of the Lunz Formation were deposited during of the so-called Carnian Pluvial Event. They are the only siliciclastic sediments embedded in purely carbonatic formations. The paper brings the first provenance analysis of this formation from the Western Carpathians (Slovakia), where it occurs in the Hronic...

This study aims at quantitative kinematic analysis of fault-slip data and palaeostress reconstruction of polyphase brittle structures developed in the Manin Unit cropping out in the Middle Vah River Valley of western Slovakia. The Manin Unit neighbours the Pieniny Klippen Belt that follows the boundary between the Paleogene accretionary wedge of th...

D. Plašienka, J. Michalík, J. Soták & R. Aubrecht comment: In their recent paper, Golonka et al. (2015) described the Cretaceous and Palaeogene olistostromes and other types of mass-transport deposits occurring within the Pieniny Klippen Belt (PKB) of the Western Carpathians. After a short introduction into the olistostrome concept and an overall d...

Abstrakt New data gathered in the Pieniny Klippen Belt (PKB) and adjacent zones along the Central–External Carpathians boundary in western Slovakia allow for a formulation of an updated model of its structure and tectonic evolution. In general, these zones evolved as an accretionary complex in front of the prograding Central Western Carpathian orog...

The causes for the Middle to Late Jurassic tectonic processes in the Northern Calcareous Alps are still controversially discussed. There are several contrasting models for these processes, formerly designated “Jurassic gravitational tectonics”. Whereas in the Dinarides or the Western Carpathians Jurassic ophiolite obduction and a Jurassic mountain...

We present results of reinvestigation of two areas where, according to published geological maps, the Meliatic rocks should occur as tectonic slices inserted between the Turnaic Slovenská skala Nappe and the underlying Palaeozoic complexes of the Gemericum. However, these occurrences were not confirmed by our research. Instead, we document a contin...

Although no undoubted oceanic crustal rock complexes of Penninic affinity participate in the present surface structure of the Western Carpathians, indirect lines of evidence suggest prolongation of the South Penninic-Vahic oceanic tract into the ancient Carpathians. The sedimentary record of both the syn-rift and syn-orogenic clastic deposits revea...

Continental core complexes are generally interpreted to result from extensional doming due to gravity-driven upflow of lower crust. In contrast, the Vepor Dome is characterized by the lack of inverted density profile and relatively cold metamorphic field gradient which precludes an activation of Rayleigh-Taylor instability. Instead, the crustal str...
