Opis:: The paper presents a set of maps illustrating the internal geometry of the Upper Cretaceous-Danian sedimentary sequence in the Polish Lowlands. Qualitative lithofacies are used for reconstructions with the dominant lithofacies component and accessory components indicated. The following maps are produced: (1) base Upper Cretaceous structural map; (2) Upper Cretaceous (including Danian) thickness map; (3) thickness map of succession K3 (Cenomanian–lower Turonian, excluding the upper Albian cycle K3-I, which is the lowermost cycle of succession K3, but formally belongs to the Lower Cretaceous); (4) succession K4 (upper Turonian–Danian) thickness map. The maps of successions K3 and K4 illustrate the post-inversion geometry of the basin for the pre-inversion (Cenomanian–lower Turonian) and syn-inversion (upper Turonian–Danian) successions. Thickness analysis shows an increasing difference in subsidence rate during the Late Cretaceous between the areas extending on the two sides of the present-day Mid-Polish Swell. Much higher subsidence rates during deposition of succession K4 occurred in the area extending to the SW of the swell. The maximum subsidence zone migrated with time from the Pomeranian and Kujavian segments towards the Kujavian and Lublin segments. The lithofacies pattern is presented in seven maps constructed for individual eustatically and tectonically controlled cycles: K3-II–K3-III (early Cenomanian–early late Cenomanian), K3-IV (latest Cenomanian–early Turonian), K4-I (late Turonian–Coniacian), K4-II (Santonian–earliest Campanian), K4-III (late early Campanian–earliest Maastrichtian), K4-IV–K4-V (late early Maastrichtian–late Maastrichtian) and Pc-I (Danian–?earliest Selandian).

Opis:: Silurian strata, stretching along the western margin of the East European Platform from the Baltic to the Black Sea, represent a potential target for both conventional and unconventional hydrocarbon exploration. Distribution of the black shale facies, prospective for shale gas, and the reef facies, prospective for oil, has been studied in respect of palaeoenvironments. The Silurian sequence has been investigated in the territory of Ukraine (Volyn-Podillyan Plate, Dobrogean Foredeep) and correlated with the data on Moldova and Romania (Moldovian Platform). The occurrence of Silurian strata, their thickness, and petrographic and lithological characteristics allowed reconstructing the distribution of open-shelf, reef and lagoonal facies. The reef facies migrated during the Wenlock–Middle Pridoli, shifting towards the open sea and back towards the shore, and therefore has been termed a migrating reef facies. Correspondingly, the boundary between the open-shelf and reef facies was shifting. The facies distribution was controlled by the transgressive-regressive cycles, which caused the fluctuations of the shelf water depth in different time intervals of the Silurian. The shelf water depth of about 100 m, where the top of the oxygen-minimum layer impinged on the sea bottom, was the boundary between the open-shelf facies, represented by organic-rich sediments, and the reef buildups.

Opis:: Praca jest podsumowaniem wieloletnich badań autora prowadzonych nad stratygrafią, litologią i paleogeografią kredy górnej Niżu Polskiego. W wyniku syntezy danych z 1018 otworów wiertniczych skonstruowano 6 map litofacjalno-paleogeograficznych, odpowiadających wydzielonym dla basenu późnej kredy na obszarze Niżu Polskiego cyklom transgresywno-regresywnym: K3-II–K3-III (wczesny cenoman–starszy późny cenoman), K3-IV (najmłodszy cenoman–środkowy turon), K4-I (późny turon–koniak), K4-II (santon–najstarszy kampan), K4-III (młodszy wczesny kampan–najstarszy mastrycht) i K4-IV–K4-V (młodszy wczesny mastrycht–późny mastrycht). Na mapach zastosowano jakościowe rekonstrukcje litofacjalne, ze wskazaniem na dominujący składnik litologiczny oraz składniki litologiczne towarzyszące. Wydzielono dziewięć kategorii litofacjalnych, odpowiadających określonym środowiskom i systemom depozycyjnym. Są to litofacje: kredy piszącej, węglanowa (wapienna), węglanowo-krzemionkowa, marglista, ilasto-marglista, mułowcowo-marglista, mułowcowo-piaszczysto-marglista, węglanowo piaszczysta i piaszczysta. W ramach prac nad prezentowaną w artykule wersją map, autor dokonał też kompleksowej analizy materiałów z wierceń Niżu Polskiego, uwzględniając przede wszystkim profilowania geofizyki wiertniczej. Niektóre profile wierceń zostały zweryfikowane i ponownie zinterpretowane. W szczególności, akcent położono na analizę poziomów twardych den, przerw sedymentacyjnych i wszelkich przejawów cykliczności sedymentacji. Umożliwiło to, w kilku przypadkach, logiczne korelacje odpowiadających sobie kompleksów litologicznych, które wcześniej stwarzały problemy interpretacyjne i były niewłaściwie skorelowane. Scharakteryzowano ogólne następstwo litofacji w basenie, zaprezentowano uwagi o subsydencji i batymetrii basenu oraz przedyskutowano pokrótce problem inwersji tektonicznej bruzdy śródpolskiej. Przedstawiona także została historia rozwoju litofacjalnego basenu późnej kredy.
The report is a general overview of the author’s many-year studies on the Late Cretaceous stratigraphy, lithology and paleogeography of the Polish Lowlands. Six lithofacies maps are presented for individual transgressive-regressive cycles in the Late Cretaceous of the Polish Basin: K3-II–K3-III (Early–early Late Cenomanian), K3-IV (latest Cenomanian–Middle Turonian), K4-I (Late Turonian–Coniacian), K4-II (Santonian–earliest Campanian), K4-III (late Early Campanian–earliest Maastrichtian), K4-IV–K4-V (late Early–Late Maastrichtian). The maps were constructed using qualitative lithofacies reconstructions with the dominant lithofacies component and accessory components indicated. Nine lithofacies types, corresponding to specific sedimentary environments and depositional systems, have been identified within the Upper Cretaceous succession of the Polish Lowlands: chalk, carbonate, carbonate-siliceous, marl, claystone-marl, mudstone (siltstone)-marl, mudstone-sandstone-marl, sandy-carbonate and sandstone lithofacies. The present version of the maps is based on an integrated analysis of drilling materials, mainly wireline logs. Lithology and stratigraphy in some boreholes were verified and reinterpreted by the author. In particular, special emphasis was laid on analysing hardgrounds, sedimentary breaks and any signs of sedimentary cyclicity. It enabled logical correlations between corresponding lithological complexes, which were previously incorrectly correlated. General succession of lithofacies in the basin is characterised, remarks on its subsidence and bathymetry are presented and a brief discussion of the problem of Late Cretaceous tectonic inversion of the Mid-Polish Trough is given. The report also presents the history of lithofacies evolution in the Late Cretaceous basin.

Opis:: Sedimentological analysis of the Early Jurassic Höör Sandstone in Central Scania, Sweden shows that two units representing different lithofacies may be distinguished. The lower Stanstorp Member is characterised by texturally and mineralogically heterogeneous sediments. Mature arenites and immature quartz and subarkosic wackes form two clearly separated groups, interpreted as fluvial channel and alluvial plain deposits respectively. The fluvial character of this member is supported by a dominance of unidirectionally oriented trough sets, abundant plant detritus, the presence of plant roots and palaeosols and a lack of marine body fossils and trace fossils. An intercalated composite polymict conglomerate layer is interpreted as the result of an extraordinary flood. The overlying Vittseröd Member is characterised by mature quartz arenites and large-scale tabular sets with multidirectional orientations. The Vittseröd Member arenites are of storm- and possibly tide-dominated shoreface origin. Bidirectional wave and tide-induced longshore currents and unidirectional onshore migration of sand ridges were the chief depositional processes. Longshore currents towards the NNW prevailed. Upper flow regime features, and erosion and reworking of sediments are attributed to the storm-induced rip currents. Lithofacies characteristics are used to define the following lithostratigraphical units: the Stanstorp and the Vittseröd members, as well as the Höör Sandstone (Fm) above. Lithofacies and palaeoenvironmental characteristics of the Vittseröd Member and their comparison with the facies of the Helsingborg and Döshult members in Western Scania suggest a Sinemurian age for the Vittseröd Member.

Opis:: The Hoanh Bo Basin is a multiple period formed basin which is associated with the tectonic mechanism due to the activity of the Chi Linh-Hon Gai and Trung Luong Faults during the late Paleogene – early Neogene time. The basin is filled with continental sediments, comprising mainly polymictic conglomerates, sandstones, siltstones, claystones and shales. Coarser-grained polymictic deposits predominate along the northern and western margins of the basin, while different types of siltstones, claystones, even sandstones occur in its center, as well as along its southern and eastern parts toward the Ha Long Bay. The source rocks for sedimentary materials are mainly originated from rocks of the Hon Gai and Ha Coi Formations. Based on the dominant grain-size class, texture, stratification, degree of clast rounding and sorting, 17 lithofacies were determined in the Hoanh Bo Basin infill. The basin is filled by gravelly, sandy and fine-grained lithofacies just covers a modest area but it represents a full of succession of 4 depositional systems including alluvial fan, fluvial, deltaic and lacustrine environments. Alluvial fan and fluvial environments are characterized by an assemblage of lithofacies such as sand- and mud-supported disorganized breccias (Gb), clast- to sand-supported conglomerates (Gmm), clast-supported inverse-graded conglomerates (Gig), planar-cross-bedded conglomerates (Gp), trough cross-bedded conglomerates (Gt), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), trough cross-bedded sandstones (St), ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), massive sandstones (Sm), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C); the deltaic assemblage is dominated by planar-cross-bedded conglomerates (Gp), horizontally stratified conglomerates (Gh), planar cross-bedded sandstones (Sp), horizontally bedded sandstones (Sh), low-angle cross-bedded sandstones (Sl); while the lacustrine assemblage consists of ripple cross-laminated sandstones (Sr), horizontally bedded sandstones (Sh), normally graded sandstones (Sng), massive mudstones, siltstones (Fsm), laminated siltstones and mudstones (Fl), massive claystones (Fm) and coaly lithofacies (C).

Opis:: Markov chain analysis was applied to studies of cyclic sedimentation in the Coal Complex of the Bełchatów mining field (part of the Bełchatów lignite deposit). The majority of ambiguous results of statistical testing that were caused by weak, statistically undetectable advantage of either cyclicity over environmental barriers or vice versa, could be explained if only the above-mentioned advantages appeared in the neighbourhood. Therefore, in order to enhance the credibility of statistical tests, a new approach is proposed here in that matrices of observed transition numbers from different boreholes should be added to increase statistical reliability if they originated in a homogeneous area. A second new approach, which consists of revealing statistically undetectable cyclicity of lithofacies alternations, is proposed as well. All data were derived from the mining data base in which differentiation between lithology and sedimentary environments was rather weak. For this reason, the methodological proposals are much more important than details of the sedimentation model in the present paper. Nevertheless, they did reveal some interesting phenomena which may prove important in the reconstruction of peat/lignite environmental conditions. First of all, the presence of cyclicity in the sedimentation model, i.e., cyclic alternation of channel and overbank deposits, represents a fluvial environment. It was also confirmed that the lacustrine subenvironment was cut off from a supply of clastic material by various types of mire barriers. Additionally, our analysis revealed new facts: (i) these barriers also existed between lakes in which either carbonate or clay sedimentation predominated; (ii) there was no barrier between rivers and lakes in which clay sedimentation predominated; (iii) barriers were less efficient in alluvial fan areas but were perfectly tight in regions of phytogenic or carbonate sedimentation; (iv) groundwater, rather than surface flow, was the main source of CaCO3 in lakes in which carbonate sedimentation predominated; (v) a lack of cyclic alternation between abandoned channels and pools with clayey sedimentation; (vi) strong evidence for autocyclic alternation of phytogenic subenvironments and lakes in which carbonate sedimentation predominated was found in almost all areas studied.

Opis:: The Markov chain analysis was used to study on lithofacies sequences in alluvial fans enclosed in the main seam of the "Bełchatów" lignite deposit. Quantitative approach supported the qualitative results of sedimentological analysis - the origin of muds, clays and coaly clays as well as the presence of a barrier (peat bog) between the fans and the lake with carbonate deposition. It was found that ephemeral lakes located on the fan surface were favourable sites for development of peat bogs. Similarly, the same lakes evolving into the peat bogs were favourable environments for expansion of sand lobes of the fans. It was discovered that cyclicity in sediment succession was disturbed by erosion. The new model of lacustrine limestone deposition was proposed for the northwestern part of lake which borders the fans from the northwest.

Opis:: The results of lithofacies analysis of clay-marl package (CMP) at Northern Prospect of Petrikov potash deposit are discussed. The analysis has been undertaken to increment waterproof thickness. Lithofacies subdivision has been carried out with ArcGIS 10 software. The following three lithofacies have been defined: sulfate-carbonate-clay, sulfate-clay-carbonate, and clastic-carbonate-clay. An inclusion of gypsum-bearing sub-package of the CMP into the waterproof thickness, based on the lateral lithofacies variation of rocks, will allow pillar mining at the areas, where the mining is prohibited at present by local regulatory documents.
W pracy omówiono wyniki analizy litofacjalnej warstwy ilastomarglistej (WIM) północnej części Pietrykowskiego złoża soli potasowej na Białorusi przeprowadzonej w celu rozpoznania warstw nieprzepuszczalnych. Rejonizację litofacjalną wykonano za pomocą programu ArcGIS 10. Wyróżniono trzy litofacje: siarczanowo-węglanowo-ilastą, siarczanowo-ilasto- -węglanową oraz klastyczno-węglanowo-ilastą. Włączenie do warstwy nieprzepuszczalnej subwarstwy gipsowej WIM, które oparto na lateralnej zmienności litolofacjalnej skał, w przyszłości pozwoli na eksploatację złoża systemem filarowym. Obecnie eksploatacja złoża jest zabroniona.

Opis:: The Stormberg Group comprises the Molteno, Elliot and Clarens formations and is one of four stratigraphical groups that make up the Karoo Supergroup in South Africa. The group is the highest unit in the Karoo Basin, representing the final phase of preserved sedimentation. The major problem with the Stromberg Group is that the mode of transport, hydrodynamic energy conditions and depositional environment are still poorly understood. For the present paper, grain size and lithofacies studies on selected sandstones from the Molteno, Elliot and Clarens formations were performed so as to elucidate their textural characteristics, depositional processes, sedimentation mechanisms and hydrodynamic energy conditions and to discriminate different depositional environments. The statistical parameters of grain size distribution (mean grain size, standard deviation, skewness and kurtosis) show that the sandstones are predominantly unimodal, fine grained, moderately well sorted, mesokurtic and near symmetrical. The bivariate diagrams of the aforementioned statistical parameters demonstrate that river and aeolian dune had the greatest impact on the depositional environments. Likewise, the C-M pattern (Passega diagram) shows that the sandstones were mostly deposited through tractive current process. Furthermore, the C-M diagram reveals the prevalence of rolling, suspension and graded suspension modes of sediment transportation. Seventeen sedimentary lithofacies were identified and grouped into seven lithofacies associations. These lithofacies associations indicate braided channel, overbank and swamp deposits for the Molteno Formation, alluvial fan/floodplain and playa deposits for the Elliot Formation and aeolian deposits for the Clarens Formation.
