The early Alpine tectonic evolution of the Western Carpathian orogenic system is differentiated into four main periods: (i) Middle-Late Triassic rifting and spreading of the Meliata Ocean, but its relationships to the Tethyan realm remain uncertain; (ii) Jurassic subduction of the Meliata oceanic lithosphere and coeval rifting of the Carpathian lower plate and oceanic breakup and spreading of the Atlantic-related Piemont-Váh Ocean, as well as short-term back-arc rifting of the Adriatic upper plate; (iii) Early Cretaceous slow and continuous but intermittent growth of the asymmetric, doubly vergent orogenic wedge still driven by the Meliata slab, concurrently with expansion of the outer Pennine oceanic zones; and (iv) Late Cretaceous to Middle Eocene northward drift of the Adriatic microplate with Austroalpine domains appended at its front that eliminated the external oceanic zones with intervening continental ribbons and sequentially accreted the Carpathian Penninic units. While dynamics of the periods (i) and (iv) was governed by the large-scale plate motions, periods (ii) and (iii) are interpreted as driven by the self-generated forces exerted by the subduction pull of oceanic and lower continental lithosphere. Tectonic evolution of particularly the latter two periods is documented in detail by rich structural, sedimentary, metamorphic, and magmatic rock records. It is inferred that periods of accelerating activity of the orogenic wedge progradation, distinguished as the regional tectonic phases, resulted from interactions between buildup of tectonic stresses and their structural realization dependent on the rheological properties of crustal rocks.

“…For the terms in brackets, the ISS values were computed autonomously in particular sub-regions In the Western Carpathians, the main region of higher ISS values is limited by important tectonic lines: mainly by the west boundary of the Central Slovak Fault System and the south boundary of the Muráň fault zone (Figure 7). These are the most marked limits of the most consolidated central part of the Western Carpathians (the Fatra-Tatra neotectonic block, after Fusán, Ibrmajer, Kvitkovič, & Plančár, 1981), characterized by the thickest crust (Bielik et al, 2018) and lithosphere (Alasonati Tašárová, Fullea, Bielik, & Środa, 2016;Dérerová, Zeyen, Bielik, & Salman, 2006) and extensive remnants of Neogene planation surfaces in the south (e.g., Lacika, 1993;Vojtko et al, 2017). The late neotectonic uplift and consequently small erosional dissection mainly in the intramountain basins keep the region very far from the topographic steady state, which corresponds to the independence of the ISS from height.…”

Metamorphic Conditions of Neotethyan Meliatic Accretionary Wedge Estimated by Thermodynamic Modelling and Geothermobarometry (Inner Western Carpathians)

et al. 2020

Metamorphic evolution of an accretionary wedge can be constrained by a reconstructed P–T conditions of the oceanic and continental margin fragments. This paper deals with the metamorphic overprinting of the Inner Western Carpathians (IWC) Meliatic Triassic–Jurassic paleotectonic units after the closure of the Neotethyan Meliata Basin. Medium to high-pressure and lower temperature conditions were estimated by Perple_X pseudosection modelling, combined with garnet–phengite, calcite–dolomite and chlorite thermometers and chlorite–phengite and phengite barometers. The Late Jurassic subductional burial to a maximum 50 km depth was estimated from the Bôrka Unit continental margin fragments at 520 °C and 1.55 GPa. This is compatible with the metamorphic peak garnet–glaucophane–phengite assemblage of blueschist facies in metabasites. The Jaklovce Unit oceanic fragments were subducted to maximum 35–40 km at 390–420 °C and 1.1–1.3 GPa. Metabasalts and metadolerites contain winchite, riebeckite, actinolite, chlorite, albite, epidote and phengite. A glaucophane-bearing metabasalt recorded an intra-oceanic subduction in blueschist-facies conditions. Rare amphibolite-facies metabasalts of this unit indicate the base of an inferred oceanic crust sliver obducted onto the continental margin wedge. The Meliata Unit oceanic/continental margin flysch calciclastic and siliciclastic metasediments suggest the burial to approximately 15–20 km at 250–350 °C and 0.4–0.6 GPa. This is indicated by a newly formed albite, K-feldspar, illite–phengite and chlorite associated with quartz and/or calcite and dolomite in these rocks. Magnesio-hastingsite to magnesio-hornblende bearing metagabbro with newly formed metamorphic magnesio-riebeckite and actinolite is an inferred detached Meliatic block tectonically emplaced in a Permian salinar mélange in the Silica Nappe hanging wall. Reconstructed P–T paths indicate variable metamorphic conditions from the medium-pressure to high-pressure subduction of the Bôrka and Jaklovce units to the Meliata Unit shallow burial in an accretionary wedge during Late Jurassic to Early Cretaceous Meliaticum evolution. Mélange blocks of Meliaticum incorporate different juxtaposed Meliatic paleotectonic units exposed in nappe outliers overlying the IWC Gemeric and Veporic superunits.
