Opis:
This is the first Paratethyan record of a minute scallop species Parvamussium fenestratum (Forbes, 1844). The species was found in Middle Miocene (Upper Badenian) clayey deposits in the Surzha borehole, the Ukrainian Carpathian Foredeep Basin. Examination of other Parvamussium specimens stored in the Museum of the Earth in Warsaw and in the Hungarian Natural History Museum in Budapest revealed further Paratethyan records of Parvamussium fenestratum. These specimens, previously referred to Parvamussium felsineum (Foresti, 1893), were identified in the Middle Miocene faunas of Poland (Monastyrz and Długi Goraj, Roztocze Hills) and Hungary (Makkoshotyka, Tokaj Mts.). In the Mediterranean Neogene this extremely rare species has been reported from the Lower Miocene (uppermost Burdigalian) of Italy and from the Lower Pliocene (Zanclean) of Spain. Research on the Oligocene-Miocene succession in the Paratethys has shown representatives of Parvamussium Sacco, 1897 to be moderately abundant in clayey facies in different basins and the genus is regarded as biostratigraphically important. Data on the distribution of other Paratethyan and Neogene Mediterranean Parvamussium species viz., Parvamussium bronni (Mayer, 1861), P. duodecimlamellatum (Bronn, 1831), P. felsineum (Foresti, 1893) and P. miopliocenicum (Ruggieri, 1949) are reported. Finally, palaeobiological and palaeobiogeographical characteristics on the genus Parvamussium Sacco, 1897 the Early Cretaceous to Recent time span are described.

Opis:
Globorotaliids of the Skawina Formation (Badenian) come from deposits representing CPN 7 (Orbulina suturalis Zone) and CPN 8 sub-evaporite Wielician (Globigerina druryi–G. decoraperta Zone alias Uvigerina costai Zone) age. There are two taxonomic groups of globorotaliids in the studied material: globoconellids (Globoconella bykovae and G. minoritesta) and jenkinsellids (Jenkinsella mayeri and J. transsylvanica). There are five stratigraphically-rank intervals of these foraminifers prior to the Middle Badenian salinity crisis in Central Paratethys. The investigated Badenian begins with G. bykovae–J. mayeri association followed by the first occurence (FO) of J. transsylvanica. The closing member of the CPN 7 biozone is the G. bykovae–J. transsylvanica assemblage. The jenkinsellids disappear during CPN 7: J. mayeri first and J. transsylvanica after. Since the base of CPN 8 in situ jenkinsellids have not been noted in the Badenian deposits. The CPN 8 begins with a stratigraphic interval barren of globorotaliids (biozone IIC in the Polish Paratethys). It is followed by episodic appearances of globoconellids (G. bykovae and G. minoritesta) in the sub-evaporite Wielician (IID biozone in Poland). G. minoritesta has been found in only one case so far. The globorotaliid stratigraphic units are distinct and well-correlated with changes in climate and the circulation of water masses in Paratethys. This study provides additional data on Mi3 in Paratethys. It documents a cryptic cooling event in the late Orbulina suturalis Zone (mid CPN 7) located at the late IIA–B assemblage (alias upper lagenide zone) in regional biostratigraphic scale. The event is recorded by J. transsylvanica Acme, matching with circa 1‰VPDB δ18O positive excursion. The event must have resulted in a considerable sea level drop – a trigger of the Moravian ecosystem demolition in the Paratethys environment.

Opis:
The Middle Miocene (Badenian) gypsum sequence was investigated by means of facies analysis on the Miechów Upland in the environs of Racławice, about 40 km northeast of Cracow. The region lies at the northwestern margin of the Carpathian Foredeep and has been omitted in detailed investigations until now. Five gypsum facies were distinguished: giant gypsum intergrowths, grass-like gypsum, palisade gypsum, sabre gypsum and microcrystalline gypsum. Except for the palisade gypsum, the other facies were described from the adjacent Nida area. The vertical arrangement of the facies is generally the same along entire northern margin of the Carpathian Foredeep. The studied sequence is reduced in thickness (up to 30 m) in comparison to the Nida area (up to 50 m). The lower part of the section, composed of the giant gypsum intergrowths and grass-like gypsum, is distinctively reduced. It is often replaced by a thin layer of palisade gypsum. The microcrystalline gypsum and the sabre gypsum are the most common facies. The giant gypsum intergrowths and the grass-like gypsum occur in the northern part of the Racławice area, while the palisade gypsum dominates in the southern part. The gypsum basin of the Miechów Upland developed in a similar way as the basin of the Nida area, but was shallower and its brines underwent more often dilution. The basin-floor morphology probably showed a variety of features.read in the deeper waters of the northwestern Proto-Caribbean basin.
Badeńskie osady ewaporatowe zapadliska przedkarpackiego wzbudzają coraz większe zainteresowanie dzięki rozwojowi analizy facjalnej. Utwory gipsowe Wyżyny Miechowskiej w południowej Polsce były omijane w dotychczasowych szczegółowych analizach ze względu na brak dużych odsłonięć w tym rejonie. W niniejszej pracy przedstawione są pierwsze wyniki analizy facjalnej gipsów okolic Racławic w południowej częoeci Wyżyny Miechowskiej, 40 km na północny-wschód od Krakowa (Fig. 1). W pracy porównano profil gipsowy badanego obszaru z dobrze rozpoznanym profilem gipsów nadnidziańskich. Osady ewaporatowe Wyżyny Miechowskiej są podoecielone przez utwory dolnego lub środkowego badenu, do których należą piaski heterosteginowe oraz warstwy baranowskie (Fig. 2; Krach, 1947; Radwański, 1968). Gipsy mogą również leżeć bezpośrednio na górnokredowym podłożu (Radwański, 1968). Osady ewaporatowe są przykryte przez utwory górnego badenu lub sarmatu lub przez utwory czwartorzędowe (Osmólski, 1972; Woiński, 1991). Badaniami objęto 10 następujących odsłonięć: Kowary, Małoszów, Pałecznica, Podgaje, Głupczów, Racławice-źródło, Racławice-góra Widnica, Kooeciejów, Kowalówka i Działoszyce (Fig. 3). Wyróżnionych zostało pięć facji gipsowych: gipsy szklicowe, gipsy trawiaste, gipsy palisadowe, gipsy szablaste i gipsy mikrokrystaliczne (sensu Bąbel, 1999a, oprócz gipsów palisadowych). Gipsy szklicowe i trawiaste występują na badanym obszarze jedynie w postaci niewielkich bloków i rumoszy (Głupczów, Kooeciejów, Kowalówka, Działoszyce) dlatego nie zostały one dokładnie scharakteryzowane. Gipsy palisadowe, gipsy szablaste i gipsy mikrokrystaliczne są odsłonięte stosunkowo dobrze (Fig. 4). Gipsy palisadowe, po raz pierwszy opisane szczegółowo w niniejszej pracy, a stwierdzone już przez Bąbla (1987, Pl. 7, Fig. 2; 1990, Phot. 3-5, 16) są zbudowane z kryształów gipsu osiągających do 0.7 m długości, podobnych do kryształów szklicowych (Fig. 5). Kryształy palisadowe mają kształt zbliżony do prostopadłościanów i nie tworzą zrostów. Częste są ślady rozpuszczania. Gipsy palisadowe tworzyły się w podobnych warunkach jak gipsy szklicowe (Bąbel, 1999a; Kasprzyk, 1999; Peryt, 1996). Narastały one na dnie płytkiego basenu ewaporatowego w postaci zwartych pokryw. Krystalizacja gipsu była często przerywana epizodami dopływu wysłodzonych wód, które częściowo rozpuszczały powsta ły gips. Gipsy szablaste zbudowane są z długich, zakrzywionych kryształów gipsu, przypominających szable (Fig. 6; Bąbel, 1999a; Kasprzyk, 1999; Peryt, 1996 etc.). Warstwa gipsów szablastych dzieli się na dwie części, dolną i górną, o różnym wykształceniu. W dolnej części przestrzenie pomiędzy kryształami szablastymi (do 0,5 m długości) wypełnione są przez chaotycznie ułożone, drobne kryształy o pałeczkowatym pokroju. Struktura ta przypomina gipsy szkieletowe sensu Kasprzyk (1993). W górnej części przestrzenie pomiędzy kryształami szablastymi (do 1,18 m długooeci) wypełnia gips mikrokrystaliczny. Sedymentacja gipsów szablastych przebiegała identycznie jak na Ponidziu (Bąbel, 1999a; Kasprzyk 1993, 1999). Kryształy narastały na dnie basenu w solance o rozwarstwieniu gęstościowym. Pod koniec sedymentacji zasolenie wzrosło na tyle, iż doszło do krystalizacji gipsu w toni wodnej. Gipsy mikrokrystaliczne są zbudowane z bardzo drobnych kryształów gipsu (do 0,05 mm, Kwiatkowski, 1972; Niemczyk, 1988; Kubica, 1992; Bąbel, 1999a). Najczęstszymi strukturami sedymentacyjnymi są: płaska laminacja, laminacja falista, powierzchnie rozmycia, brekcje, mikrouskoki i mikrofałdy (Fig. 7). Ślady po kryształach halitu występują rzadko. Gipsy mikrokrystaliczne powstały z osadzenia na dnie basenu kryształów wytrąconych w toni wodnej lub redeponowanych (Pawlikowski, 1982; Bąbel, 1999a; Kasprzyk, 1999). Do nasycenia solanki względem halitu dochodziło epizodycznie. Gipsy mikrokrystaliczne zostały częściowo diagenetycznie przekształcone w gipsy porfiroblastyczne (Bąbel, 1992). Gipsy szablaste i mikrokrystaliczne są najbardziej rozprzestrzenione i występują na całym badanym obszarze (Fig. 8). Gipsy palisadowe dominują na południu badanego terenu, pomiędzy Kowarami i Głupczowem, podczas gdy gipsy szklicowe i trawiaste występują głównie na północ od Głupczowa (Fig. 8). Pionowa sukcesja gipsów Wyżyny Miechowskiej jest stała, identyczna jak w całym północnym obrzeżeniu zapadliska przedkarpackiego (Fig. 9). Całkowita miąższooeć sekwencji gipsów rzadko osiąga 30 m, czyli jest o ok. 20 m mniejsza niż na Ponidziu (Fig. 10). Szczególnie zredukowana jest dolna część profilu obejmująca gipsy szklicowe i trawiaste, które często zastąpione są jedną cienką warstwą gipsów palisadowych (Fig. 10). Przebieg sedymentacji gipsów nie odbiegał znacząco od sedymentacji gipsów Ponidzia. Basen Wyżyny Miechowskiej był prawdopodobnie płytszy i miał bardzo urozmaiconą morfologię dna. Często dochodziło również do rozcieńczania wód basenu przez wody z lądu.

Opis:
Zooxanthellate corals in the Badenian (Langhian to lower Serravallian) of western Ukraine occur in different lithofacies, but are most abundant in the upper Badenian coralgal reefs of the Ternopil Beds. The coral assemblage consists of five genera, with two predominant (Tarbellastraea and Porites) and three strongly subordinate (Favia, Heliastraea, Siderastrea). The present study is the first record of Heliastraea defrancei in the Fore-Carpathian Basin. The taxonomic composition of the corals indicates that their development occurred in conditions of some ecological stress, most probably connected with climate (location at the northern limit of coral distribution) and sedimentary environment (possible influx of terrigenous material). The coral assemblage shows similarities to numerous fossil reefs of Miocene age from the Paratethyan and Mediterranean realms.

Opis:
The facies variation of the Badenian sulphate deposits in the Polish Carpathian Foredeep Basin reflects distinct depositional and diagenetic environments. In these environments the primary sulphate (mainly gypsum) was deposited and then underwent different pathways of diagenetic evolution, recognized on the basis of sedimentological, petrographic and geochemical studies. Diagenetic sulphate facies (anhydrite and secondary gypsum) formed in successive stages: syndepositional (the depositional stage), early diagenetic (at the surface and during shallow burial) and late diagenetic (during deeper burial and exhumation). Most anhydrite deposits show sedimentological and petrographic features characteristic of a diagenetic facies formed by replacement (anhydritization) of the precursor gypsum deposits. Four basic genetic models of anhydrite have been proposed: (1) syndepositional interstitial anhydrite growth de novo, (2) syndepositional anhydritization (via nodule formation and pseudomorphous replacement), (3) early diagenetic anhydritization (displacive anhydrite growth), and (4) late diagenetic anhydritization (replacive anhydrite growth). The succession of diagenetic processes and their paragenetic relationships within the Badenian sulphate deposits display a complex diagenetic evolution. Many controlling factors, such as a palaeogeographic setting, tectonic activity, geostructural constraints and physico-chemical changes of the pore fluids, related to sedimentary and diagenetic environments, have been involved in the sulphate diagenesis. The results may be applied to other ancient evaporite basins including the marginal gypsum deposits and anhydrite in the more buried, basinward part.

Opis:
Pale brownish celestine-rich salt rocks were found near the Franciuszek Müller gallery, in the chambers of the 3rd level in the Wieliczka Salt Mine. The complex of rock salts subjected to exploration occurred within a large seam approximately 15 m thick. Detailed research revealed that the salt has the form of a block incorporated within the gray salts body and being similar to other blocks of green salts, well known in the upper part of the deposit. A characteristic petrographical feature of the pale brown rock salt owed to the presence of celestine (SrSO 4 ). That strontium mineral was re-examined, using X-ray powder data, and scanning microscope observations, with EDS analysis. The investigated rock salts exhibited a mineral association of halite (main component), anhydrite, celestine, calcite, gypsum, clay materials, iron compounds and a small amount of bitumen. Interrigenous sediments and the insoluble part of salt occurred higher content of strontium that in halite. Celestine crystals were observed in two forms: elongated platy crystals, forming fan-shaped aggregates and granular aggregates, strongly associated with anhydrite. On carbonate and sulphate strontium usually appearing as needle shaped aggregates of celestine. No barium minerals were observed. The development and paragenesis of celestine suggested a post-sedimentary origin of these rocks that ought to be connected with diagenetic processes. An important observation that confirmed that thesis was the transformation of fine crystalline anhydrite into platy crystals, recrystallization and primary accumulation of strontium, as a result of evaporation processes.

Opis:
Study of foraminiferal and dinoflagellate cyst assemblages and palynofacies occurring in 2 m-thick marls cropping out beneath a giant gypsum intergrowth unit in the Borków gypsum quarry in Southern Poland, one of the key Badenian evaporite sections in the Polish Carpathian Foredeep Basin, has shown the presence of 49 species of benthic foraminifers and 11 species of planktonic ones, and 51 dinoflagellate (including 8 redeposited ones). The composition of the foraminiferal fauna and its isotopic signal indicate temperature-stratified, nutrient-rich and thus less-oxygenated marine water. Changes in the relative abundance of epifaunal and infaunal species indicate a clear environmental change during the deposition of the marls. A middle to outer shelf marine, well-ventilated environment with moderate primary productivity existed during the deposition of the bottom part of the marls. Subsequently, infaunal bottom-dwellers became dominant due to a massive increase in food supply to the sea bottom and shallowing of the sea to inner - middle shelf depths, and than a decreasing trend of a relative abundance of the infaunal morphogroups is observed until the top of the marls that were deposited in an inner shelf environment with moderate primary productivity. The calculated palaeotemperatures for particular foraminifer taxa (Globigerina spp., Cibicidoides and Bulimina elongata) show a slight upsection decrease and a decrease in the temperature differences between the bottom and intermediate water beds. Palynofacies are composed of elements of mixed origin, including terrestrial, marine (mainly dinoflagellate cysts) and elements of uncertain derivation (structureless organic matter). The palynological content of most samples indicates their deposition in an open-marine marine environment, in the stable marine conditions of an open shelf basin with no salinity fluctuations. The sample just below the gypsum contains no dinoflagellate cysts, perhaps due to a drastic change in the photic zone leading to a complete collapse of the dinoflagellate flora. Very rare occurrence of planktonic foraminifers in that sample suggest the shallowing of the basin accompanied by a decrease in the temperature gradient between the upper (warmer) and lower (colder) water beds. A shallow, cold water marine environment is indicated for the topmost foraminiferal assemblage.

Opis:
The Badenian (Middle Miocene) evaporite deposits of the Carpathian Foredeep in Poland, Ukraine and Czech Republic, contain large bottom-grown primary gypsum crystals (selenite) which are some of the largest in the world. The 0.5-3.5 m long crystals are arranged in a palisade manner and create specific intergrowths similar to the contact swallow-tail {101} twins known in other areas. They occur in one stratigraphical interval that is several metres thick. The largest specimens were found near Busko in Southern Poland. The selenite crystals are commonly 1-1.5 m long, but specimens exceeding 2.5 m in length are present but are rare and poorly documented. Some years ago one specimen approaching 3.5 m in length was recognized at Bogucice-Skałki and seems to be the largest known and existing mineral crystal in Poland. Recently another ca. 3.5 m long selenite specimen was exposed at nearby Gacki. Both these crystals are partly damaged, and one is not fully exposed, and therefore it is difficult to establish which is (or was) actually the largest one.

Opis:
Multiproxy sedimentological, gamma-spectrometric, foraminiferal, calcareous nannoplankton, and otolith data were used for the reconstruction of the Badenian (Middle Miocene) history of the Moravian part of the Carpathian Foredeep. The study material originated from the new borehole LOM-1, which drilled >20 metres of monotonous clayey siltstones with exceptionally rich and well-preserved microfossil assemblages. Distal parts of the Carpathian Foredeep (a forebulge depozone) are exposed in this succession. Generally, a quiet environment of outer shelf to upper bathyal of monotonous clayey silts was interpreted, which is typical for the proximal parts of a peripheral foreland basin. The section studied can be subdivided into six intervals, confirming the cyclical character of Middle Miocene sedimentation in the Central Paratethys. Interannual oscillations of nutrient content, temperature and/or salinity are interpreted based on the oscillations of geochemical as well as palaeobiological data. The turnover connected with the initiation of the Middle Miocene Climatic Transition is recorded above the LO (last occurrence) of Helicosphaera waltrans in agreement with previous observations in the Carpathian Foredeep. The changes include cooling, a decrease in nutrients, a probable increase of the salinity of surface water, and increase of seasonality. Seasonality was manifested by an alternation of mixed and stratified water columns with a seasonal input of nutrients. Concerning nutrients, sources of seasonal riverine input or seasonal upwelling are both possible.

Opis:
The Middle Miocene (middle Badenian) "gypsum-ghost" limestones composed of calcite and/or sulphur pseudomorphs after selenitic gypsum, are a salient feature of the Polish sulphur deposits from the northern Carpathian Foredeep (S. Poland). Sulphurous rocks (including the gypsum-ghost limestones) are present within the evaporite unit, the so-called "Chemical Series", and are commonly believed to be lithological equivalents of synchronous gypsum deposits, resulting from regionally extensive, wholesale replacement of the sele-nite lithofacies by limestones and limestone + native sulphur. However, detailed geochemical examination of regional major and minor element compositions in these unusual carbonates suggests considerable internal differences. Distinct variations in chemical distribution along the main development of the Osiek-Baranów Sandomierski native sulphur deposit, together with the associated barren limestone areas, are clearly recognized. The pattern of the geochemical parameters of these gypsum-ghost limestones is inconsistent with an epigenetic model of formation of the Polish sulphur deposits (wholesale replacement of sulphate deposits by carbonates + native sulphur) and argues for their formation within a sedimentary-early diagenetic regime.

Opis:
Foraminifers occurring in marls underlying the Middle Miocene Badenian gypsum in the northern Polish Carpathian Foredeep in one borehole section [Młyny (Busko) PIG 1] and in two dewatering pits in operating quarries (Leszcze and Borków) contain well-preserved foraminifers. Sixty-seven species of benthic and twenty-one species of planktonic foraminifers are recorded in the 12-m-thick section of the Młyny borehole. Benthic assemblages are characterized by the dominance of Bulimina and Uvigerina while planktonic assemblages are composed mainly by warm-water orbulinids and Globigerinoides spp. in the lower part of the Młyny section and by temperate-cold water Globigerina spp. in the upper part of the Młyny section as well as the Leszcze and Borków sections. The taxonomic composition of foraminiferal assemblages makes it possible to distinguish two foraminiferal zones in the Młyny borehole: the Orbulina suturalis and Uvigerina costai zones, and only the latter zone is accessible at Leszcze and Borków. The benthic foraminiferal successions in the studied interval suggest oxygenation and productivity changes in the Carpathian Foredeep Basin prior to the Badenian salinity crisis. Four intervals of lowered oxygenation and/or elevated organic flux to the sea-floor are recognized; the intervals in which foraminiferal assemblages suggest marine environments with lowered oxygenation in bottom waters alternate between the intervals where stress markers form less than 50% of the benthic foraminiferal assemblages. Benthic assemblages are moderately to highly diversified, and species have more equal frequencies. The upsection decrease in the proportion of planktonic foraminifers reflects the shallowing of the basin accompanied by a decrease in the temperature gradient between the upper (warmer) and deeper (colder) water beds. The average palaeotemperature of water based on d18O of Uvigerina and Globigerina decreased by ca. 2 and ca. 6°C, respectively (from 9.9 and 17.4°C in the Orbulina suturalis Zone to 7.9 and 11.5°C in the Uvigerina costai Zone, respectively). Below the gypsum, the d18O values of both benthic and planktonic foraminifers show quite large variations possibly due to the salinity increase. Coeval domination of benthic foraminiferal assemblages by Bulimina suggests increased surface water productivity and an increased organic flux to the sea-floor prior to the onset of evaporite deposition and/or salinity increase.

Opis:
The most abundant benthic foraminifers recorded in the Wielician salt-enclosed xenoliths are: Bulimina spp., Uvigerina spp., Valvulineria complanata, and Cibicides pseudoungerianus. The predominant taxon in the planktonic assemblage is Globigerina bulloides with a median 98.9% in biozone IIC and 89.1% in the later IID. The IIC assemblage differs from the IID one in both taxon composi tion and abundance. The most pronounced differences are those revealed by Valvulineria complanata counts, number of benfhic taxa and the plankfonic/benthic (P/B) rafio. Pseudotriplasia minuta (one of the Wielician index taxa) occurs only in the IID biozone, present in 16 among 28 samples. There is a noticeable difference in sur- face sculpture morphology pattern in the predominant Bulimina and Uvigerina taxa in the IIC versus the IID biozones. There are smooth (Bulimina elongata) and weakly striate (Uvigerina semiornata plexus) forms in the IIC biozone, foll owed by heavily costate (Bulimina striata) and spinose-pustu l ate (Uvigerina orbignyana plexus) forms in the IID. Globigerina druryi and G. decoraperta- the CPN 8 planktonic index taxa - had not been found in the material studied. Globigerinita uvula is un- usually common in the samples studied. The samples analysed display an abundance of Globigerina bulloides typical of the sub-evaporite Wielician. Hence the studied Wielician stratotype area supports the thesis of the Globigerina bulloides Acme as the valid name designation for the substage.

Opis:
The Badenian section of Anadoly near Kamyanets Podilskyy (Ukrainian Carpathian Foredeep Basin) consists of the Tyras Fm. (gypsum and Ratyn Limestone) and the Ternopil Mb. of the Kosiv Fm. The latter are 5.3 m thick and are composed of dark grey mudstones with limestone intercalations. This study indicates the occurrence of over 54 species of benthic foraminifers and 10 species of planktonics. Benthic foraminifera are represented mainly by calcareous forms; agglutinated tests are very rare. Planktonic foraminifera appear in the upper part of the succession studied. Five benthic foraminiferal assemblages are recognized: A (Elphidium/Lobatula/Astrononion) B (Hauerinidae), C (Cibicidoides/Lobatula), D (Porosononion) and E (Uvigerina/Bulimina). The foraminiferal record indicates deposition in a shallow subtidal environment (20 m depth) of normal marine salinity and temperate waters followed by gradual deepening of the basin to >50 m. Analysis of foraminiferal assemblages indicates that bottom waters were highly oxygenated during deposition of the lower and middle parts of the Anadoly sequence. During deposition of the upper part of the sequence the oxygenation of bottom water gradually decreased, as expressed by a large decrease in the proportion of oxic species and an increase in dysoxic ones. The same set of samples yielded low amounts of palynological organic matter represented by dominant black opaque phytoclasts; bisaccate pollen grains and dinoflagellate cysts are rare. Taxonomically impoverished assemblages of the latter consist of dominant Polysphaeridium and Cleistosphaeridium placacanthum associated with Lingulodinium machaerophorum and a few other taxa. The taxonomically richest assemblage was found in the topmost sample. These changes were interpreted as indicative for increased salinity in the surface water layer, with its maximum in the middle part of the section; the assemblage from the topmost part is characteristic for normal marine salinity.
