“…Paleocene assemblages of agglutinated foraminifera from the Eastern Carpathians (Romania) were mentioned in the Tarcău Nappe (between Suceava and Bistriţa valleys) by Ionesi and Tocorjescu (1968), Săndulescu (1973), Dicea (1974), Ionesi (1974), Bindiu and Filipescu (2011) and Mare (2014). Similar assemblages from equivalent formations in other areas of the Carpathians were studied by Szczechura and Pozaryska (1974), Olszewska (1981, 1982), Geroch and Nowak (1984), Bubík (1995), Olszewska (1997), Cieszkowski and Waśkowska-Oliwa (2002), Bąk (2004), Oszczypko et al (2005), Waśkowska-Oliwa (2008), Cieszkowski et al (2012), Waśkowska et al (2014).…”

Representative assemblages of agglutinated foraminifera from the Paleocene deposits of the Suha outcrop in the Tarcău Nappe (Eastern Carpathians, Romania) were analyzed using diversity indices, morphogroups and foraminiferal biofacies in order to describe the paleoenvironmental and palaeobathymetrical conditions of the studied area. The results suggest bathyal environments, close to the Carbonate Compensation Depth (CCD) and a flysch type biofacies. The assemblages are dominated by coarsely agglutinated flysch-type taxa: tubular (Nothia, Rhizammina, Rhabdammina), globular (Saccammina), flattened planispiral and streptospiral (Rzehakina) and flattened streptospiral forms (Paratrochamminoides and Trochamminoides). The agglutinated foraminifera morphogroups display variations through the section suggesting changes in the amount of organic matter, oxygen and seafloor disturbance caused by the local influence of the turbiditic flows. Based on the presence of the index taxa Rzehakina fissistomata throughout the entire section, the deposits were assigned to the Paleocene Izvor Formation.

Abstract:The Karpatian deposits of the central part of the Carpathian Foredeep in Moravia, which are deeply buried under the Outer Western Carpathians, provide a unique opportunity to reconstruct the former evolutionary stages of this peripheral foreland basin and its paleogeography. A succession of three depositional units characterized by a distinct depositional environment, provenance, and partly also foreland basin depozone, have been identified. The first depositional unit represents a proximal forebulge depozone and consists of lagoon-estuary and barred coastline deposits. The source from the "local" crystalline basement played here an important role. The second depositional unit consists of coastline to shallow marine deposits and is interpreted as a forebulge depozone. Tidalites recognized within this unit represent the only described tide-generated deposits of the Neogene infill of the Carpathian Foredeep basin in Moravia. The source from the basin passive margin (the Bohemian Massif) has been proved. The third depositional unit is formed by offshore deposits and represents a foredeep depozone. The provenance from both passive and active basin margin (Silesian Unit of the Western Carpathian Flysch Zone) has been proved. Thus, both a stepwise migration of the foredeep basin axis and shift of basin depozones outwards/cratonwards were documented, together with forebulge retreat. The shift of the foreland basin depozones more than 50 km cratonward can be assumed. The renewed thrusting along the basin's active margin finally completely changed the basin shape and paleogeography. The upper part of the infill was deformed outside the prograding thrust front of flysch nappes and the flysch rocks together with a strip of Miocene sediments were superposed onto the inner part of the basin. The width and bathymetric gradient of the entire basin was changed/reduced and the deposition continued toward the platform. The basin evolution and changes in its geometry are interpreted as a consequence of the phases of the thrust-sheet stacking and sediment loading in combination with sealevel change.

“…Fossils: Red algae-Sporolithon, Lithothamnion, and Mesophyllum-and bryozoans-Cyclostomata and Cheilostomata-are the main components of the facies association. Additionally, Corallinaceae are represented by Arhaeolithothamnion, Paleothamnium, Ethelia, Lithoporella, Spongites, Neogoniolithon, Distichoplax, and Karpathia (e.g., [38,45,105,106]). They occur mainly as bioclasts in organodetritic limestones, but also as components of organic buildups.…”

“…The large concentrations of the bioclasts were basis for distinguishing "allodapic" limestones (calcareous turbidites) or so-called clastic limestones, such as the Bircza Limestone [37,38], Łu żna Limestone [39,65,107,115], Koniaków Limestone [116], and Skalnik Limestone [40,117,118]. So-called Lithothamnion sandstones/beds such as Goryczkowiec, Czerwin, Klokočov, and Stráž sandstones [18,42,106,110,[119][120][121] belong to this group. Numerous rhodoids are known from the thick-bedded deposits of the Silesian Nappe [22,101,104,105,122].…”

The present work focuses on palaeogeographic reconstruction of shallow-water carbonate deposition in the Outer Western Carpathian Tethys. Platform deposits are preserved only as a component of turbidites and olistostromes, and reconstructions of these platforms are based on clastic material redistributed into slopes and deep basins and occurring among the Outer Carpathian nappes. Similar platforms were also present on the Tethys margins. These reconstructions were performed using the global models of plate tectonics. Several ridges covered by carbonate platforms developed in that area during the latest Jurassic–Palaeogene times. Three main shallow-water facies associations—Štramberk, Urgonian, and Lithothamnion–bryozoan—could be distinguished. The Tithonian–lowermost Cretaceous Štramberk facies is related to early, synrift–postrift stage of the development of the Silesian Domain. Facies that are diversified, narrow, shallow-water platforms, rich in corals, sponges, green algae, echinoderms, foraminifera, microencrusters, and microbes are typical of this stage. The Urgonian facies developed mainly on the south margin of the Outer Carpathian basins and is characterised by organodetritic limestones built of bivalves (including rudists), larger benthic foraminifera, crinoids, echinoids, and corals. Since the Paleocene, in all the Western Outer Carpathian sedimentary areas, Lithothamnion–bryozoan facies developed and adapted to unstable conditions. Algae–bryozoan covers originating on the siliciclastic substrate are typical of these facies. This type of deposition was preserved practically until the final stage in the evolution of the Outer Carpathian basins.
