Abrămuţ Basin
Opis:
Detailed lithostratigraphic data from a borehole in the Abrămuţ Basin, located in the northwestern part of Romania, has revealed the presence of turbiditic deposits containing several layers with tuff/tuffaceous materials in the lower Badenian. The age of these deposits is determined by the presence of the foraminifera Praeorbulina glomerosa and Orbulina suturalis. Detailed quantitative and qualitative X-ray diffraction data (XRD) on 10 different tuff layers situated at depths between 2450 and 2640 m show a mineralogical association comprising analcime, quartz, volcanic glass, smectite, mica, calcite, K-feldspar, glass and minor quantity of chlorite and albite. The presence of analcime suggests that the albite isograd for the interval studied has been never reached and the maximum temperatures have been lower than c. 125degrees C since the early Badenian.

Opis:
The Shaximiao Formation (Sichuan Basin, China), and the corresponding Chuanjie Formation of the neighboring Yunnan Basin (Sichuan-Yunnan Basin), representing continental Mesozoic strata, are distinguished from other Chinese Mesozoic units because of the large area over which they are distributed, their lithological characteristics and their abundant vertebrate fossils. This paper analyses and summarizes the dinosaur fossils from the Shaximiao Formation and compares them to other vertebrate groups of the same or similar ages, both in China and abroad. For the first time, this paper presents the viewpoint that the upper member of the Shaximiao Formation is of Middle Jurassic age (Bathonian–Callovian). Furthermore, we claim that the entire Shaximiao Formation is of Bajocian–Callovian age (middle-late part of Middle Jurassic). This conclusion is supported by the age inferred from invertebrate fossils and radiometric dating (165–178 Ma). The composition, evolution and geological age of the vertebrate fauna (particularly dinosaur fossils), as well as their comparison to the dinosaur fauna from the other parts of the Sichuan-Yunnan Basin (Chuanjie Fm.) is discussed. Middle Jurassic dinosaur assemblages from China show marked differences compared with other dinosaur assemblages in the world, and this is explained by geographical isolation.

Opis:
The Late Cretaceous to Oligocene strata of the Dukla Nappe, which is a part of the accretionary wedge formed in front of the Carpathian orogen, record a history of the basin development from remnant to foreland basin stages. The lower part of the succession indicates the first stage of basin evolution characterized by turbidite systems fed from the E (NE) to W (SW). The system encompasses deposits of the Łupków and Cisna formations deposited in a channel-lobe transition (Łupków Fm.) and in sandstone-rich channelized lobes (Cisna Fm.) The transitional phase is represented by deposits of the Submenilite Formation derived from two different sources (SE and N) and deposited in a submarine slope/ramp environment. The third stage of basin evolution is marked by the advancing front of the Carpathian orogen resulting in peripheral foreland basin development. Increased tectonic activity led to a switch in sediment source from the SE to the NW, more complex topography of the basin and a change in sediment distribution. The initial phase of this stage is characterized by low-density turbidites and suspension fall-out sediments of the Menilite Fm. Discrete tectonic pulses are recorded by the thick Cergowa sandstones, mostly deposited by hybrid flows and high-density turbidity currents. A decrease in tectonic activity is suggested by heterolithic deposits of the Krosno Fm. capping the sedimentary succession.

Five Middle Triassic crinoid taxa: Eckicrinus radiatus (Schauroth, 1859), Holocrinus acutangulus (Meyer, 1847), H. dubius (Goldfuss, 1831), Dadocrinus sp. and Encrinidae gen. et sp. indet., from the North-Sudetic Basin, are described. The occurrence of Eckicrinus radiatus (Schauroth) is reported in the area for the first time. Based on the stratigraphic distribution of the crinoids, the ranges of three crinoid zones (Dadocrinus Zone, acutangulus Zone and dubius Zone) have been constrained. A modified correlation between the Lower Muschelkalk deposits of the North-Sudetic Basin, Upper Silesia and the Holy Cross Mountains is proposed.

Opis:
Evolution of the Pomeranian Basin (NW Poland) dur ing the Devonian saw the development of a characteristic siliciclastic and mixed siliciclastic-carbonate marginal marine-to-open marine carbonate sedimentary succession. This was controlled via proximity of the land areas representing uplifted parts of the East European Craton (EEC): the Fennoscandian High extending in the north, and the Mazury–Belarus High, situated in the east. The depositional history of the Pomeranian Basin began not earlier than at the end of the Emsian or possibly in the Eifelian, after a long break spanning the Lochkovian, Pragian and much of the Emsian when the area was subjected to erosion. Sedimentation started in the north eastern part with marginal-marine clastic deposits with local evaporites which are dated as uppermost Emsian?–Eifelian, passing upwards into lower–middle Givetian marginal-marine siliciclastic and carbon ate de posits; these are followed by upper Givetian marginal-marine siliciclastic rocks. In the south western part of the area, the Devonian succession started with marginal-marine carbonates and siliciclastics which belong to the upper most Emsian?–Eifelian, followed by lower and middle Givetian carbonates, passing upwards into upper Givetian marginal-marine siliciclastics. During the Late Devonian the Pomeranian Basin underwent evolution from a marginal-marine in the earliest Frasnian, through carbonate ramp or platform/shelf basin settings during the rest of the Frasnian and early Famennian, up to a reappearance of shallow subtidal and marginal-marine environments in late Famennian time. At the end of the Famennian an open shelf environment became prevalent almost over the whole area and continued up to the Mid Tournaisian. The lateral relation ships of the lithofacies during the Givetian, Frasnian and Famennian are portrayed on 11 maps, showing relatively short time-intervals, selected to depict the most sigificant environmental changes.

Opis:
In the area of the Polish Basin five deep seismic sounding profiles, recorded during 1991–1997, were used to compare the structure of the crystalline and consolidated crusts with that of the sedimentary cover. Repeated reactivation of deep crustal fractures controlled the thickness distribution and development of faults in Palaeozoic andMesozoic sequences.NW–SE toWNW–ESE basin-parallel and transverse N–S to NE–SW striking fracture systems are evident. The former includes the isseyre–Tornquist Zone that marks the profound crustal boundary between the East European Craton and the typical Trans-European Suture Zone (TESZ) crust that is characterized by a variably thick consolidated upper crustal layer, composed of Caledonian-deformed Early Palaeozoic and possibly Vendian sediments, and defines the NE boundary of the Permian and Mesozoic Mid-Polish Trough (MPT). Its northwestern TTZ segment was intermittently active throughout the whole geological history of the area. The SWboundary of the TESZ, marked by the Dolsk Fault across which the consolidated crustal layer is replaced by a crystalline Variscan upper crust, is only evident on profiles LT-7 and P4. The deformation front of the Variscan Externides is located some 100 km to the NE of the Dolsk Fault within the confines of the TESZ crust. On profiles TTZ-PL and P2, significant lateral changes in the thickness of the consolidated and crystalline crust of the Pomeranian, Kuiavian and Holy Cross Mts. segments of the MPT are noted that coincide with the transverse Bydgoszcz-Poznań-Toruń and Grójec fault zones. These crustal changes are associated with substantial changes in the composition and thickness of supracrustal sedimentary sequences and the degree of inversion of the MPT.

During the Middle Ordovician, the salt deposits of the Majiagou Formation of the Ordos Basin in North China formed, the halite including various genetic types of fluid inclusion. In this study, fit-testing of primary inclusions was performed to reconstruct the physical and chemical conditions during original halite sedimentation. During the post-sedimentation stage, salt was subjected to elevated temperatures (62-70°C) and pressures of tens of megapascals. From these measurements and mathematical calculations, the gas pressure was identified in the primary fluid inclusions, which allowed us to estimate that the brine column thickness in the salt basin was approximately 40 m.

Opis:
A summary of known crinoid taxa in the Polish part of the Triassic Germanic Basin, including their presence elsewhere, is documented. At present, 13 taxa and 3 ecophenotypes of crinoids have been recorded from that area, only one of them being endemic. In the Lower Muschelkalk and lower part of theMiddleMuschelkalk, taxa widespread both in the Tethys and Germanic Basin, or Tethyan taxa, dominate. In the Upper Muschelkalk crinoids are very rare in Poland, being represented by Encrinus liliiformis and Holocrinus sp. Many of the species occurring in the central part of the Germanic Basin in the Upper Muschelkalk have not been recorded in the eastern part of the basin. The degree of endemism of the crinoid fauna in theMuschelkalk is markedly lower than the degree of endemism of the rest of the benthonic macrofauna. This probably resulted from huge number of crinoids forming "crinoid gardens" that produced large number of larvae, increasing the chances of successful geographical expansion of crinoids.

Vertebrate remains, mostly fish teeth and scales, are described from the Lower Muschelkalk of Raciborowice Górne, North-Sudetic Basin, SW Poland. The assemblage occurs in dark grey organodetrital limestone of unit C. Vertebrate remains, represented mainly by vertebrate bones and coprolites, are also known from unit B. Five taxa of chondrichthyan teeth — Acrodus lateralis, Acrodus cf. lateralis, Acrodus sp., Palaeobates angustissimus, Palaeobates sp. and, for the first time from this region, two taxa of osteichthyan remains — teeth of Birgeria sp., scales from Gyrolepis sp. as well as scales from unclassified actinopterygians and enigmatic bones (fishes?) are described from the Lower Muschelkalk at Raciborowice Górne. Reptile teeth represent ing the Nothosauridae or Cymatosauridae have been found for the first time at this locality. They were discovered in the Bone Bed of unit C, that had previously only yielded fish teeth. The material collected has allowed reconstruction of the vertebrate as semblage of the Lower Muschelkalk of the North-Sudetic Basin. It has also helped to constrain reconstructions of the palaeoenvironment, sugesting that it represented a deepening lagoon. The assemblage has been correlated with age-equivalents from other regions of Europe, the faunas from the Holy Cross Mts. (Central Poland) being the closest analogy. The evidence indicates that, during the deposition of units Band C that, contain the vertebrate remains, connection with the Tethys Ocean was through the Silesian–Moravian and East Carpathian marine gateways.

Opis:
The Callovian and Oxfordian marine sediments of the Jaisalmer Basin constitute the uppermost part of the Jaisalmer Formation, which comprises the Kuldhar and Jajiya members. In the present paper the authors illustrate retrogradational-progradational, more or less symmetrical cycles representing low- to high-energy marine environments. Despite an incomplete sedimentary record in a profile disrupted by a number of omission surfaces, it is possible to distinguish seven such sedimentary cycles in less than 24 m of sedimentary succession. The cycles, often bearing in their upper parts a thick-bedded well-cemented calcareous sandstone/pack- to rudstone, or hummocky cross-stratified beds indicative of storm events, are occasionally topped by hardgrounds. Hardgrounds provide well-defined boundaries useful for delineating correlative/bounding surfaces, identified here with sequence boundaries (3rd order cycles). Maximum flooding surfaces characterized by richly fossiliferous marly wackestones provide additional correlative horizons. Within these sequences, subordinate cycles can be tentatively distinguished, some of them may represent parasequences. The stratigraphical significance of correlative surfaces and sequences is tested by their fossil content, and these surfaces can be used for regional correlations with neighbouring basin.

Opis:
The paper presents the changes of coal seams quality near fault zones. Three types of relations have been found. The first one shows an increase of coal quality at the 0.2 m distance from fault surface, as a result of increase of coalification degree. It is assumed that, this type was caused by heat of friction which was rising during faulting. It is revealed as an increase of such parameters as: caking properties, vitrinite reflectance, calorific value and carbon content, as well as the decrease of oxygen, ash, and moisture content. The second type presents differed degree of coal quality decrease. This type was produced due to hypergenic processes. The author found four subtypes of oxidation-type changes of coal quality parameters in fault zones. The first one shows the highest level of hypergenic processes in a coal seam about 1 m off a fault plane. The second presents minor degree of oxidation processes in the coal seam at a smaller distance from the fault. The third one demonstrates minimum oxidation changes of coal quality at a distance of 0.2 m from the fault. The fourth subtype of the oxidation changes of coal quality has been observed only in tectonic breccia and not in the coal seams itself.The third types demonstrates faults which do not show any impact on changes of coal quality parameters. To this type belong faults from SW part of USCB and faults with downthrown up to 20 m.

Opis:
The uppermost Westphalian marine horizon (Dunbarella horizon) is especially important for correlation of Carboniferous deposits in the Lublin Coal Basin and in other basins of the Northwest European Carboniferous Basin. The Dunbarella horizon is characterized by cyclic sedimentation and consequent faunal spectrum variability, typical for Westphalian marine horizons of northwestern Europe. Palaeontological study of the Dunbarella horizon showed the presence of macrofauna representing different palaeoenvironments, from marine to brackish (non-marine) and freshwater conditions. The vertical sea level fluctuations and changes in seawater salinity resulting in palaeontological record changes do not link with geochemical proxies. TOC, redox-sensitive trace element concentrations, and V/Cr, Ni/Co and V/(V + Ni) ratios generally suggest that the Dunbarella horizon sediments were deposited under predominantly oxic conditions (with local exceptions during the initial phase of the Dunbarella ingression; Kopina 1 borehole).

One hundred twenty five miospore taxa were determined and two miospore zones were distinguished. Deposits from Konradów and Biały Kamień belong to the Stenozonotriletes triangulus-Rotaspora knoxi (TK) Zone, correlated to the middle Namurian A. Deposits from Szczawno Zdrój appeared to be younger, because they represents the Lycospora subtriquetra-Kraeuselisporites ornatus (SO) Zone (late Namurian A).
