“…The same assemblage was determined in the ŠVM‐1 well (102.3 m). In the ŠVM‐1 well (Kováč et al ., ), the basal part of the Pannonian (Tortonian) sequence may be an bioevent equivalent of the Mecsekia ultima Zone in Hungary (Sütő‐Szentai, , ) or Mecsekia ultima–Spiniferites bentorii pannonicus (Mul‐Spa) Zone (Bakrač et al ., ), which developed from the Sarmatian (late Serravallian; ca . 11.5–11.3 Ma) zones.…”

“…In the M‐1 well, situated in the southern margin of the Želiezovce depression, the Pannonian (Tortonian) sediments at the depth of ca 1000 m belong to the Spiniferites bentorii pannonicus–S. bentorii oblongus Assemblage Zone, and can be correlated with the S. bentorii oblongus Zone (Sütő‐Szentai, , , ; Magyar et al ., ; Bakrač et al ., ) within the time interval 11.3–10.75 Ma. Towards the overlying strata, the Spiniferites bentorii coniunctus–Pontiadinium pecsvaradensis Assemblage Zone (900–800 m) was documented, and can be correlated with the Pontiadinium pecsvaradensis Zone (Sütő‐Szentai, , , , ; Magyar et al ., ; Bakrač et al ., ) with a time interval between 10.75–10.6 Ma.…”

Changes in Cenozoic depositional environment and sediment provenance in the Danube Basin

et al. 2017

The Danube Basin is situated between the Eastern Alps, Western Carpathians and Transdanubian mountain ranges and represents a classic petroleum prospection site. The basin fill is known from many 2D reflection seismic lines and deep wells with measured e-logs which provided a good opportunity for theories about its evolution. New analyses of deep wells situated in the Danube Basin northeastern margin allowed us to refine stratigraphy and to interpret various depositional systems. This also allowed us to outline changes in provenance of sediment during the Cenozoic. The performed interpretation of the Palaeogene and Neogene depositional systems also confirmed the Oligocene-Early Miocene exhumation of the basin pre-Neogene basement. Opening and development of the Middle to Late Miocene basin depocentres above the boundary between the Western Carpathians and Northern Pannonian domain was recognized. Our analysis contributed to a better understanding of the Hurbanovo-Di€ osjen} o fault which acts as an inherited weakness zone along the boundary of two crustal fragments with different provenance. We document various basin types stacked one on another (retro-arc, back-arc and extensional hinterland basin). The analysis of sediment sources reveals intricate geodynamic processes during the Eastern Alpine-Western Carpathian orogenic system collision with European platform (formation of ALCAPA microplate) and its successive tectonics escape during the Pannonian Basin System origination.

This paper presents the results of a mineralogical, petrographic and palynological study of selected Pannonian calcareous marl and sandstone samples penetrated by the Hódmezővásárhely-I (Hód-I) well, Endrőd Formation (Tótkomlós Member, cores 35 and 40, 5167.0-5183.0 m and 5468.0-5486.0 m, respectively); this formation is part of the Makó Trough of the Pannonian Basin, SE Hungary. The studied sections comprise mixed carbonate-siliciclastic rocks with abundant silt-to sand-sized angular grains such as monocrystalline and polycrystalline quartz, muscovite, biotite, chlorite, carbonate and metamorphic rock fragments. This polymictic and immature clast composition reflects the importance of local provenance, suggesting that intrabasinal structural highs represent additional source areas to the basin. Palynological analysis was carried out on selected core segments of the well in order to provide a biostratigraphic framework and palaeoenvironmental interpretation for the studied interval. In the investigated samples two biozones were distinguished: the Spiniferites bentorii oblongus Zone and the Spiniferites paradoxus Zone. The successive changes of the dinocyst assemblages reflect changes in the distance from the shoreline or the terrestrial input from the margin of the Makó Trough. The older assemblage indicates a more proximal setting in relation to the shoreline and/or a higher terrestrial input; the younger dinocyst assemblage -with a more open-water taxa point in relation to a greater distance from the shoreline -represents an increase in the water level, and/or decreased terrestrial input. The predominance of membranous dinocysts in this assemblage indicates a fluctuation in the lake surface salinity, or possibly a shift to a holoplanktonic lifestyle due to periodical oxygen depletion in the water column. The assemblages of both zones demonstrate their regional distribution throughout the whole Pannonian Basin and therefore they can be used to document regional scale trends in phytoplankton communities, as well as implying the communication of water bodies. The colour and preservation of the palynomorphs suggests significant burial heating and the high maturity of the sedimentary organic matter. In the studied samples a series of paragenetic events have been identified using petrographic methods. Early diagenesis was generally represented by cementation (i.e. of framboidal pyrite and carbonates with variable iron content) and weak mechanical compaction. On the other hand, late diagenesis involved pressure solution (chemical compaction), cementation (late pyrite) and, occasionally, dolomite replacement and mineral transformation (smectite to illite) processes. It is noteworthy that in these two core sections neither significant macroporosity nor microporosity were observed, this being due to pervasive cementation.Keywords: Pannonian, endemic, dinocysts, Spiniferites, diagenesis, paragenetic sequence ÖsszefoglalásMunkánkban a Hódmezővásárhely-I fúrás 35. és 40. magfúrási szakaszaiból (5167,0-5183,0 m, ill...

“…2C). As a consequence, a new pattern of crossed exchanges of organisms between the Mediterranean and the Dacic Basin during high sea-level episodes can be tested to explain the episodes of Lago Mare 1 (before the peak of the MSC) and 3 (after the peak of the MSC) in the Mediterranean, as argued by Clauzon et al (2005), Popescu et al (2009), Suc et al (2011), Bache et al (2012), Bakrač et al (2012) and Do Couto et al (2014).…”

Since the discovery of calcareous nannofossils, dinoflagellate cysts and planktonic foraminifers in deposits from the Dacic Basin, intensive research has been performed in order to evidence which gateway this microplankton used to connect Paratethys and the Mediterranean prior and after the Messinian Salinity Crisis (MSC). Such a gateway is also to be regarded at the origin of successive influxes of Paratethyan organisms (molluscs, ostracods, dinoflagellates) into the Mediterranean Basin ("Lago Mare" events). Observing that the İ stanbul area, usually proposed for this purpose, was inefficient, we examine the succession of marine well-dated pre-MSC and post-MSC deltaic deposits through the Balkans, from northern Greece to southern Romania, that constitutes a reliable candidate for such a marine corridor, the origin of which was caused by the regional tectonic extension. The reconstructed palaeogeography for high sea level episodes that encompassed the MSC clarifies the context of the so-called North Aegean Lake. This marine gateway probably evolved as a powerful river during the peak of the MSC, contributing to the deposition of clastics in the hydrocarbon Prinos Field. A tectonically controlled subsidence to the north and south of the Skopje region caused the closure of such a gateway.
