The late Paleozoic sedimentary record is well known for its mixed marine–terrestrial coal-bearing sedimentary sequences, traditionally called cyclothems, and their hypothetical glacioeustatic sea-level control. In contrast, coeval sedimentary cycles deposited in continental, nonmarine settings have received comparatively little attention. These fluvial and fluvio-lacustrine cycles are common in many late Paleozoic basins across paleoclimatic belts ranging from the tropics to the higher latitudes. Several mechanisms explaining the origins of these sequences have been suggested, including autogenic processes and tectonically driven allocycles. However, progress in understanding the climatic signal recorded in paleosols together with cyclostratigraphic analysis indicate that these terrestrial cycles record climate-driven upstream changes in sediment supply, possibly linked to astronomical (”Milankovitch”) forcing. We evaluate this hypothesis by reviewing the existing models for repetitive fluvial facies and the lateral continuity of coal-bearing fluvial cycles in the Upper Silesian Basin (~3°S paleolatitude). In this basin, mixed terrestrial–marine short eccentricity-driven coal-bearing cyclothems of Serpukhovian age are replaced in the Early Pennsylvanian by coal-bearing fluvial allocycles of the Saddle and Lower Suchá Members (Bashkirian). Facies and cyclic pattern analyses suggest that the terrestrial cycles record alternation of contrasting fluvial styles: a low sinuosity avulsive/laterally migrating sand and gravel dominated braided river and fluvial systems with well-developed floodplains and narrow channels transporting minimal sediment load across widespread peat swamps. Tonsteins in coals indicate that peat swamps were broadly isochronous over a large area. Lateraly persistent coals and fluvial channels indicate clastic deposition not coeval with periods of active peat accretion in extensive and long-lasting swamps. Cyclostratigraphic analysis together with new high-precision radioisotopic U-Pb zircon ages of three tonsteins suggest that major fluvial cycles were linked to the ~100-thousand year term of orbital eccentricity. Our conceptual model involves an upstream control on vegetation cover and sediment supply through changes in seasonal rainfall related to interactions of the summer-hemisphere monsoon and the Intertropical Convergence Zone. Furthemore, we develop an integrated time scale for the late Namurian to earliest Westphalian; the Namurian – Westphalian boundary is dated 319.17 ± 0.41 million years ago (Ma); bases of the Marsdenian and Yeadonian substages are estimated as 320.26 ± 0.43 Ma and 319.92 ± 0.43 Ma, respectively.
... These have been regarded since long time to be glacio-eustatic and, therefore, global in distribution (e.g., Ross and Ross, 1985Veevers and Powell, 1987;Izart and Vachard, 1994;Heckel, 2002;Izart et al., 2002;Haq and Schutter, 2008). Changes in the Earth's orbital parameters have been hypothesized to be the driving force since the 1930s (e.g., Wanless and Shepard, 1936;Ramsbottom, 1977;Heckel, 1986Heckel, , 1994Maynard and Leeder, 1992;Weedon and Read, 1995;Rasbury et al., 1998;Izart et al., 2003;Ueno et al., 2013). Correspondingly, assumed periods of cycles in cyclothemic successions were used to estimate durations of stages of the time scale (e.g., Heckel, 1986Heckel, , 1991Algeo and Wilkinson, 1988;Boardman and Heckel, 1989;Klein, 1990Klein, , 1991Connolly and Stanton, 1992;Dickinson et al., 1994;Heckel et al., 2007). ...

The Carboniferous Period experienced recovery and major diversification in the marine and terrestrial realms after the end-Devonian mass extinctions. Marked evolutions took place in the terrestrial realm with the development of extended forests and the appearance of reptiles and the first flying organisms. Strong faunal provincialism resulted from geodynamic and climatic changes during the Visean. The Carboniferous Period is also characterized by the onset of the Late Paleozoic Ice Age with characteristic glacial—interglacial cycles, the closure of the western Paleotethys Ocean, and the Variscan orogeny.

An analogous periodicity of sea-level change was inferred from the Donets Basin; the onlapofflap record during the Serpukhovian Stage has periodicities of ∼1 ± 0.2 Myr with moderate magnitude (Eros et al., 2012). The curves from the intracratonic Moscow Basin did not show similar period, likely due to differences in the techniques used to derive sea-level history and different accommodation histories (Izart et al., 2003;Eros et al., 2012) (Fig. 5e). Shorter-term onlap-offlap events with durations of 0.8-1.6 ...

Upper Visean Rudov Beds (V-23) are considered as one of the main source rocks within the northwestern Dniepr Donets Basin (DDB). Average TOC values within the Srebnen Bay (northwestern DDB) exceed 4% (thickness up to 100 m). Average TOC contents north and northwest of the Srebnen Bay (up to 60 m) are significantly lower (2-4%) but still sufficient for unconventional hydrocarbon production, whereas wells along the northeastern basin margin do not hold a shale oil/gas potential (<2% TOC). Insufficient information is available from positions along the basin axis in the central DDB, mainly because of considerable burial depths >5.5 km.Although hydrogen index (HI) values of the most immature samples are ≤300 mgHC/gTOC, basinal Rudov Beds host a potential to generate Paraffinic-Naphthenic-Aromatic (P-N-A) low wax oil according to pyrolysis experiments. A basinward maturity trend is visible, but the maturity cut-offs for shale oil/gas production (>0.8%Rr/>1.2%Rr) are reached at great depths (>4.5 km/5.5 km) only. Furthermore, results of kinetic experiments do not argue for presence of type IIS kerogen potentially triggering earlier hydrocarbon generation.The mineralogy of Rudov Beds varies strongly in lateral and vertical directions, limiting the predictability of mechanical behaviour. Samples from the siliceous (basinal) facies partly contain more than 60% of brittle minerals (quartz, feldspar, carbonates, etc.) suggesting a good fraccability. This value is rarely reached by samples from the transitional and lagoonal (calcareous and clayey) facies. The clay mineral fraction within many investigated Rudov samples is dominated by kaolinite, which is suggested to diminish the fraccability of shales. Apart from that, expandable clay minerals (ECM) are present in samples from more than 5 km depth, a result of low Mesozoic heat flow.

In the approximately 4400 m thick Moscovian to early Asselian succession of the Donets, six tonsteins in coals k 3 , k 7 , l 1 , l 3 , m 3 , and n 1 have been dated with an age resolution of b0.05%, or~100 ka (Davydov et al., 2010). This precision has allowed the duration of the fourth-order sequences of Izart et al. (1996Izart et al. ( , 2003Izart et al. ( , 2006 to be constrained. The calculated duration between pairs of dated tonsteins, regardless of stratigraphical position, confirmed a consistent length of 400 kyr. ...

We report field observations and interpretations from the sedimentary geology of the middle Carboniferous stratigraphy of the Donbas Foldbelt, providing new environmental information in addition to the basin reconstructions based on previous field observations, and mostly borehole and seismic data 3,12,49,[56][57][58][59] . Analysis of the sedimentary characteristics of the sandstone successions in the Donbas Foldbelt, the best exposed lithology, shows that the depositional environment varied between the terrestrial, low-energy coal environments and storm-wave base paleobathymetries: We interpret the four different groups of sandstones described above as river mouth to deltaic environments, with water depths generally confined to the upper tens of meters, above the storm wave-base. ...

The Paleozoic Pripyat-Dniepr-Donets Basin in Belarus, Ukraine and Russia forms a major hydrocarbon province. Although well- and seismic data have established a 20 km thick stratigraphy, field-studies of its sediments are scarce. The inverted Donbas segment (Ukraine) exposes the Middle Carboniferous part of the basin’s stratigraphy. Here, we provide detailed sedimentological data from 13 sections that cover 1.5 of the total of 5 km of the middle Carboniferous and assess the paleoenvironment and paleo-current directions. Middle Carboniferous deposition occurred in a shelf environment, with coal deposition, subordinate fluvial facies and abundant lower and middle shoreface facies, comprising an intercalated package of potential source and reservoir rocks. Sedimentary facies indicate a paleo-depth range from just below the storm wave base, and coal-seams represent near-coastal swamp environments. Sedimentation and subsidence were hence in pace, with subtle facies changes likely representing eustatic sea level changes. Paleocurrent directions are remarkably consistently SE-ward in time, space and across the different sedimentary facies across the Donbas Fold Belt, illustrating a dominantly sedimentary infill along the basin axis, with little basin margin influence. This suggests that the middle Carboniferous stratigraphy of the Dniepr-Donets basin to the northwest probably contains significant amounts of fluvial sandstones, important for assessment of reservoir potential.
... This paper addresses the response of Pennsylvanian fusulinids to global sea-level fluctuations and regional climate change using integrated paleontological and sedimentological observations. The Pennsylvanian succession from the Donets Basin (Ukraine) provides a near continuous record of the response of epicontinental deposition to environmental change during the dynamic climate history of the LPIA given the documented high rates of Pennsylvanian subsidence (Izart et al., 2003;Eros et al., 2012). High-precision radiometric ages (Davydov et al., 2010) provide a calibrated chronostratigraphic framework for detailed lithostratigraphic, biostratigraphic, and cyclostratigraphic study. ...

The paper presents the characteristics of profiles consisting of coarsening-upward and non-gradational cyclothems that correspond to parasequences in the Visean, Serpukhovian and Bashkirian sections of the Lublin Basin in SE Poland. The accompanying single fining-upward cyclothems are also described. Six types of cyclothems are distinguished. The most complete types of coarsening-upward cyclothems Ic, Id and incomplete IIc and IId have been identified. The least complete are non-gradational cyclothems IIIc and IIId. The cyclothems developed within the oscillating environments of shallow carbonate and clay shelf, and in shallow-water deltas. The lowstand systems tract (LST) deposits are composed of fining-upward cyclothems, rarely of coarsening-upward IId and non-gradational IIId. Within the transgressive systems tract (TST), type IIc is dominant, and the quantity of Ic and non-gradational cyclothem IIIc is moderate. The maximum flooding surface (MFS) usually occurs within coarsening-upward cyclothems IIc. The highstand systems tract (HST) consists of similar types of cyclothems as the TST, but their quantity is less. Relative sea-level fluctuations during the Carboniferous deposition in the Lublin Basin are associated with sea-level changes generated by glacial episodes in Gondwana. The relative sea-level fluctations also affected both erosional processes related to the successive relative sea-level lowstands and the formation of stratigraphic gaps. The influence of glacio-eustatic fluctuations was modified by local factors such as the supply of sedimentary material, subsidence rate and local tectonics.
... The Donets Basin is close to the Moscow Basin and is unique for many reasons. First, continuous tectonic subsidence during Pennsylvanian time (Stephenson et al., 1993(Stephenson et al., , 2001Stovba and Stephenson, 1999;van Wees et al., 1996;Izart et al., 2003) has resulted in accumulation of a nearly continuous sequence of sedimentary deposits. Second, high frequency glacial-eustatic sea-level fluctuations led to multiple switching between marine and terrestrial sedimentary regimes. ...

A fusulinoidean taxonomic study of the Gurkovo and Kalinovo sections allows us to refine the biostratigraphy of the poorly studied Myachkovian (upper Moscovian) strata of the “N” Formation in the Donets Basin. Three fusulinid biozones, Hemifusulina graciosa–Fusiella spatiosa , Fusulina cylindrica–Fusulinella pseudobocki , and Fusulinella ? kumpani , are proposed in the interval from the top of Limestone M 10 to the base of N 3 , and they are correlated with coeval strata in the historical type area of the Moscow Basin. A total of 33 fusulinid species and subspecies belonging to eight genera are described, including three new species: Hemifusulina gurkovensis n. sp., Beedeina innaeformis n. sp., and Fusulina sosninae n. sp. The main evolutionary trend in fusulinoidean morphology in the late Moscovian is the appearance of massive secondary deposits in the limestone of the “N” Formation. Specific temporal and distributional patterns of the Middle Pennsylvanian fusulinoidean assemblages indicate variations in sea level stand. Variations are cyclic, with periods ∼600,000–1,000,000 years. A Hemifusulina -association indicates the beginning of transgression; the late transgression–high sea level stand is designated by the Beedeina–Neostaffella–Ozawainella–Taitzehoella assemblage which is successively replaced by the most diverse Fusulinella -dominant association, which occupied a progressively shallowing sea. The similarity of fusulinoidean assemblages in the Moscow and Donets Basins and their cognate evolution trends reveal a connection between both regions at least during Podolskian–Myachkovian time.
