“…The Maeotian transgression (Rögl, ), reconnected the Paratethys basins again putting an end to the late Miocene dry and endorheic phase in Central Eurasia. The age of the Maeotian transgression is seriously disputed with ~5 Myr age discrepancies between the different models (11.6 Ma—Moghadam, ; 10.5 Ma—Rögl, ; Maţenco, Bertotti, Cloetingh, & Dinu, ; 9.8 Ma—Semenenko, Andreeva‐Grigorovich, Maslun, & Lulieva, ; Gozhyk, Semenenko, Andreeva‐Grigorovich, & Maslun, ; 9;.5 Ma—Nevesskaya, Goncharova, Ilyina, Paramonova, & Khondkarian, ; 8.85 Ma—Andreescu, 2009; 8.6 Ma—Vasiliev et al., ; 7.6 Ma—Trubikhin, ; Radionova et al., ) and the underlying tectonic or climatic triggering mechanisms are therefore still unexplained.…”

The end of the Great Khersonian Drying of Eurasia: Magnetostratigraphic dating of the Maeotian transgression in the Eastern Paratethys

Central Eurasia underwent significant palaeoclimatic and palaeogeographic transformations during the middle to late Miocene. The open marine ecosystems of the Langhian and Serravallian seas progressively collapsed and were replaced in the Tortonian by large endorheic lakes. These lakes experienced major fluctuations in water level, directly reflecting the palaeoclimatic conditions of the region. An extreme lowstand of the Eastern Paratethys lake (−300 m) during the regional Khersonian stage reveals a period of intensely dry conditions in Central Eurasia causing a fragmentation of the Paratethys region. This period of “Great Drying” ended by a climate change towards more humid conditions at the base of the Maeotian stage, resulting in a large transgressive event that reconnected most of the Paratethyan basins. The absence of a robust time frame for the Khersonian–Maeotian interval hampers a direct correlation with the global records and complicates a thorough understanding of the underlying mechanisms. Here we present a new chronostratigraphic framework for the Khersonian and Maeotian deposits of the Dacian Basin of Romania, based on integrated magneto‐biostratigraphic studies on long and continuous sedimentary successions. We show the dry climate conditions in the Khersonian start at 8.6–8.4 Ma. The Khersonian/Maeotian transition is dated at 7.65–7.5 Ma, several million years younger than previous estimates. The Maeotian transgression occurs later (7.5–7.4 Ma) in more marginal and shallower basins, in agreement with the time transgressive character of the flooding. In addition, we date a sudden water level drop of the Eastern Paratethys lake, the Intra‐Maeotian Event (IME), at 6.9 Ma, and hypothesize that this corresponds to a reconnection phase with the Aegean basin of the Mediterranean. Finally, we discuss the potential mechanisms explaining the particularities of the Maeotian transgression and conclude that the low salinity and the seemingly “marine influxes” most likely correspond to episodes of intrabasinal mixing in a gradual and pulsating transgressive setting.

The study is fo cused on the tax o nomic in ven tory of an in trigu ing bi valve fauna from the Lower Oligocene Menilite Beds (Dynów Marls) within the Silesian Nappe, Pol ish Outer Carpathians. Six teen bi valve spe cies have been iden ti fied within the ma te rial col lected in two small quar ries in Jabłonica Polska near Krosno. Strati graphic and geo graphic dis tri bu tions of all recog nized spe cies are con sid ered. This as sem blage, the first of this kind in Po land and one of three rec og nized in the Outer Carpathians, shows clear af fin i ties to co eval typ i cal Solenovian fau nas from Ukraine to Kazakhstan, with par tic u lar com par ison made to bi valve fau nas from the Menilite For ma tion (Subchert Mem ber) within the Boryslav-Pokuttya Nappe, Ukrai nian Outer Carpathians.

“…Wysocka) For almost two centuries, the geological record of the Fore-Carpathian Basin has attracted geological studies (e.g., Staszic 1815; Alth 1850; Hilber 1882; Łomnicki 1897, 1898Teisseyre 1900;Nowak 1938;Pazdro 1953;Kudrin 1966;Ney et al 1974). Numerous new geological and geophysical studies, related to prospecting for hydrocarbon sources, started recently (e.g., Oszczypko 1996Krzywiec 1999;Dziadzio 2000;Porębski et al 2002;Krzywiec et al 2005Krzywiec et al , 2008Mastalerz et al 2006;Popadyuk et al 2006;Ślączka et al 2006;Pietsch et al 2010;Warchoł 2011;Lis and Wysocka 2012;Gozhyk et al 2015).…”

Studies of Miocene sediments in the Fore-Carpathian Basin, conducted by geologists from the University of Warsaw have provided new insights on the distribution of the facies infilling the basin, particularly in the forebulge and back-bulge zones. The origin of the large-scale sand bodies, evaporitic deposits and large-scale organic buildups is discussed, described and verified. These deposits originated in variable, shallow marine settings, differing in their water chemistry and the dynamics of sedimentary processes, and are unique with regard to the fossil assemblages they yield. Many years of taxonomic, biostratigraphic, palaeoecologic and ecotaphonomic investigations have resulted in the identification of the fossil assemblages of these sediments, their age, sedimentary settings and post-mortem conditions. Detailed studies were focused on corals, polychaetes, most classes of molluscs, crustaceans, echinoderms, and fishes.
