“…Marls and limestone intercalations of the siliciclastic series are practically barren of fauna. It seems that the transporting agent of the carbonate as well as siliciclastic grains was the continental water, which anyway was the main inflow during evaporite deposition in the Carpathian Foredeep Basin as proved by Cendón et al (2004).…”

“…This transition reflects a major environmental change from hypersaline to marine conditions, although it should be mentioned that the geochemical modelling showed that the continental water was the main inflow source during the entire evaporite deposition in the Carpathian Foredeep Basin (cf. Petrichenko et al 1997;Cendón et al 2004). These brackish conditions apparently prevailed during gypsum precipitation and afterwards, when the basin became desiccated, forming gypsum microbialites, and then was rapidly reflooded by brackish water.…”

Abstract:The Kudryntsi section in West Ukraine documents a major environmental change from hypersaline to marine conditions during the Middle Miocene. There are very few (or no) specimens of foraminifers in samples of the siliciclastic series (4 m thick, with limestone intercalations) which occurs above the gypsum (and below the transgressive deposits) in the southern part of quarry. The limestone intercalations are first sparitic and microsparitic, and then become pelletal. The pelletal depositional textures are interpreted as originated in restricted environments in contrast to mixed-fossil lithoclastic packstones/grainstones overlying the siliciclastic series. The diversity of fauna increases up section. Foraminifers, bivalves, ostracods and gastropods appear first and then, additionally, brachiopods, bryozoans, crinoids, and echinoids occur. Foraminiferal assemblages are dominated by elphidiids forming 70 to 90 % of the population. The most common species are Elphidium crispum (Linné) and E. macellum (Fichtel & Moll). The limestones show a wide range of δ 13 C values (from -1.6 ‰ to -18.2 ‰) and δ18 O values (from -0.2 ‰ to -9.4 ‰) indicating that the cementation and some recrystallization took place in meteoric-water-dominated fluid but the restriction-controlled trend can be recognized. The siliciclastic series was deposited in an evaporitic lagoon influenced by large inflows of continental waters carrying the siliciclastic and other detrital material from the older Badenian rocks as well as from their substrate. The Kudryntsi section documents a stepwise decrease in water salinity -from ca. 150-300 ‰ during the Badenian gypsum precipitation, through ca. 80-150 ‰ during deposition of the siliciclastic series to ca. 35 ‰ during sedimentation of the basal transgressive deposits. The basal deposits originated in shallow subtidal (0-20 m) environments of normal marine salinity (30-35 ‰) and temperate to warm waters (8-18 °C) as indicated by requirements of the E. crispum association in recent seas.

“…The marine salina model, formerly mentioned by a few authors, was suggested for the Fore-Carpathian Basin, particularly for its northern Ca-sulphate margin by Peryt et al (1995), Peryt (2001Peryt ( , 2006a, Bąbel (2004bBąbel ( , 2007b and Cendόn et al (2004). This model assumes that the basin is a depression separated from the sea by a topographic barrier, and is supplied with seawater seeping through it or overflowing this barrier, occasionally in the form of short-term marine transgressions.…”

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.
