pdf Calcareous algae of the Visean-Serpukhovian boundary beds in the Izyayu River section (south of the Chernyshev Uplift)
We consider changes in the composition of the algaflora in the Visean-Serpukhovian boundary interval in the Izyayu River section. A transgressive trend in changing sedimentation conditions - from extremely shallow water at the end of the Visean to moderately deep water at the end of the Early and early Late Serpukhovian - is observed for the section as a whole. This change in sedimentation conditions led to a consistent reduction in the abundance and diversity of calcareous algae. In general, the composition of the Late Visean-Early Serpukhovian algaflora in the Izyayu River section corresponds to warm shallow-water conditions.

Keywords: calcareous algae, changing sedimentation conditions, Lower Carboniferous, Chernyshev Uplift.

pdf Late Tournaisian shallow-water sequenses of the eastern part of Timan-Pechora Province (Kozhva River)
The shallow-water Upper Tournaisian sequences of the eastern part of Timan-Pechora petroleum Province were studied with biostratigraphical (based on foraminifers, conodonts, and brachiopods) and isotope stratigraphical methods. Poor conodont associations containing Siphonodella obsoleta Hass and S. cooperi Hass are characteristic of this stratigraphic interval in the shallow-water facies. Foraminifer associations are very variable: some of them are composed of numerous late Tournaisian species (Kozhva River section), but some associations comprise just species of wide stratigraphic range. The prominent global positive shift in the carbonate carbon isotope record marks the upper Tournaisian in the region. This shift is considered as reliable stratigraphical marker.

Keywords: shallow-water sequence, Lower Carboniferous, Upper Tournaisian, biostratigraphy, isotope stratigraphy, Timan-Pechora petroleum Province.

pdf Lithofacial characteristics and organic matter geochemistry of the Devonian-Carboniferous section оf folded and thrust belt area of the Kosyu-Rogov Depression southeastern part (using Levogrubeyu-1 well data as reference source)
The results of study of the Middle-Upper Palaeozoic bioherm-shoal association in the east of the Timan-Pechora petroleum Basin (based on the Levogrubeyu-1 well description) are presented. The core lithological study allows distinguishing the facial analogues with the succession types of the Bolshaya Nadota carbonate association. It is supposed that the bioherm-shoal association demonstrates similar architecture along the all shelf border. Foraminifera and Conodont studies allow as to improve the biostratigraphic subdivision of the succession discovered by the borehole. The geochemical investigations reveal that the Devonian-Carboniferous rocks in the core samples disclose low hydrocarbon generation potential. On the other hand high hydrocarbon potential is supposed for the clayey-carbonate units of Middle-Late Frasnian age. Rock-Eval pyrolysis and the Conodont Alteration Index indicate a high level maturity of organic matter corresponding to the main gas generation zone (Ro > 1.5 %).

Keywords: lithofacial study, organic matter, hydrocarbons, Upper Palaeozoic, Kosyu-Rogov Depression, Timan-Pechora petroleum basin.

pdf Conodonts of the Devonian-Carboniferous boundary deposits of the Kozhim River key section (Subpolar Urals)
A new version of conodont biostratigraphy (based on compilation of new author’s and published materials) of Tournaisian part of the Kozhim River key section is given. The zones/subzones expansa, sulcata, Lower duplicata, Upper duplicata-sandbergi, quadruplicata and isosticha are characterized. The bases of all zonal subdivisions except for sulcata and duplicata Zones are shifted (compared to the latest versions of zonal biostratigraphy). The most reliably diagnosed zones (the base of the sulcata, duplicata, and quadruplicata Zones) are established in carbonate graded cycles (calciturbidites). The deposits of the terminal Famennian are very conditionally compared with the Lower and lower part of the Middle praesulcata Zones according to the position in the section. Absence of deposits of the upper part of the Middle and Upper praesulcata Zones suggests the presence of erosion on the D/C boundary interval. The presence of erosion on the D/C boundary interval doesn’t allow using the Kozhim River section as a key section of the stratigraphic boundary (in accordance with the tasks and rules of studying and describing the key stratigraphic sections developed by an interdepartmental stratigraphic committee). However, formally this section can be used as a key section of the structural-facial zone due to the fact that it is the most studied, and by the availability of outcrops, it exceeds all sections within the development of deep-shelf deposits of the Kozhim intra-shelf palaeodepression.

Keywords: conodonts, biostratigraphy, Famennian, Tournaisian, key section, Subpolar Urals.

pdf Lower Serpukhovian (Lower Carboniferous) of the Kozhim River basin (Subpolar Urals)
Results of study of the Visean-Serpukhovian boundary beds of the Kozhym River basin (Nizhniy Nortnichayol’ Creek) are considered. Biostratigraphy based on conodonts, foraminifers, and algae is described. The early Serpukhovian transgression led to sequential environment changes from quite-water shallow inner shoal to active-water shoal border. Correlation of the study section with sequences of the Kosyu-Rogovaya Depression allows elaborating facial model of the Lower Serpukhovian.

Keywords: Subpolar Urals, Serpukhovian, conodonts, foraminifers, algae, environments.

pdf Tournaisian deep-water deposits of the Usa River basin (Polar Urals)
The article presents new data of detailed lithological and paleontological study, and results of stratigraphical investigations of the Tournaisian deep-water deposits of the Malaya Usa River section (Polar Urals). The section is biostratigraphically characterized by conodonts, foraminifers, fishes, and corals. The traces of the Mid-Tournaisian (Lower Alum Shale) Global Event are distinguished. The lithological marker (transgressive clayey beds), biostratigraphical data (FAD of Siphonodella crenulata conodonts), and isotope anomaly (negative shift of б13С) allowed to confidently recognize the Event. The new data fill the gap in the stratigraphical characteristics of the deposits of the base of the Carboniferous System of the Polar Urals and are important for detailing correlation of the tectonically complex sections within the Vorkuta oil and gas bearing complex of the eastern part of the Timan-Pechora Basin. In addition, there are quite rare taxa in the complex of conodonts, which justify the additional paleontological interest to the present work.

Keywords: biostratigraphy, event stratigraphy, conodonts, foraminifers, Tournaisian, Polar Urals.

pdf  Local stratigraphy of the Upper Devonian – Carboniferous of the north of Pay-Khoy
Analyses of stratigraphical data on Upper Devonian and Carboniferous of the north of Pay-Khoy allow elaborating a new stratigraphic scheme comprising the Pechora and Pay-Khoy formation belts. Correlation of the local stratigraphical units of the belts is based on biostratigraphical and event-stratigraphical methods. A number of interfacial correlative levels corresponding to global eustatic events are detected, namely: Middlesex, Kellwasser, Dasberg, Hangenberg, Late Tournaisian-Early Visean, Mid-Visean, and Mid-Carboniferous.

Keywords: stratigraphical data, Upper Devonian, Carboniferous, interfacial correlative level, eustatic events, Pay-Khoy.

pdf  The late Tournaisian Event in the successions of the Kosyu-Rogovaya Depression and adjacent areas (Timan-Pechora Province)
The late Tournaisian Event (Mid-Aikuanian Event) appearing as significant changes in marine and terrestrial biota is considered as consequence of the beginning of the Early Carboniferous phase of the Gondwana glaciation and transition from the greenhouse climate to icehouse climate. The event caused one of the highest Palaeozoic shift in the carbon isotope ratio. This shift was traced in the sections of the Kosyu-Rogovaya Depression and adjacent areas: 1-Kochmes borehole, the Izyayu River section, and the Kozhym River section. The isotope shift is dated by conodonts of the Siphonodella isosticha and Gnathodus typicus zones, foraminifers Eoforschia gigantea and Dainella, and algae Exvotarisella. The traces of the late Tournaisian Event are considered as reliable stratigraphic tool for the eastern part of the Timan-Pechora Province.

Keywords: Lower Carboniferous, Tournaisian, isotopic anomaly, late Tournaisian Event, Timan-Pechora Province, Kosyu-Rogovaya Depression.

pdf  Characteristic of the pore space in the Upper-Devonian - Carboniferous Carbonate section of the Pai-Khoy Parautochthone unit
The characteristics of intergrain pore space in the carbonate deposits of the Upper Devonian - Carboniferous Pai-Khoy carbonate parautochtone unit are given. The total and open porosity of carbonate rocks is characterized by low values; however, small pores with an average diameter predominate in the pore space. The main factors controlling the values of intergranular porosity of the Upper Devonian - Carboniferous carbonates are rock texture and the degree of secondary transformations: the porosity is proportional to the detritus size and decreases in thermally matured rocks.

Keywords: intergranular porosity, carbonates, Late Devonian – Carboniferous, Pai-Khoy Carbonate Parautochtone.

Possibilities of computed microtomography application in micropalaeontological and lithological studies*
*The article is presented in two languages, Russian and English.

Possibilities of the computed X-ray and optic tomography in the micropalaeontological and lithological studies are considered. X-ray microtomography allows determining phosphate microfossils (conodonts) avoiding special sample preparation; evaluate the total porosity and concentration of sulfides. The optic microtomography promises results in histological study of conodont elements.
Key words: tomography, micropalaeontology, conodonts, foraminifers, lithology, carbonates, silicites.

pdf  Devonian and Carboniferous boundary strata in the Kamenka River section (Pechora-Kozhvin megaswell, Timan-Pechora province)
The article deals with the Devonian-Carboniferous boundary in the shallow-water strata (the Kamenka River section as example) on the basis of cyclostratigraphy (maximum of regression) controlled by biostratigraphical data (conodonts and foraminifera). Facial control on the foraminifer and conodont associations is considered. Dependence of the magnetic suscessibility of the rocks on the sea-level changes is detected. The dependence is probably caused by variations of the terrigenous content in the carbonate rocks. Keywords: conodonts, foraminifera, cyclostratigraphic method, magnetic susceptibility of rocks, Devonian-Carboniferous boundary strata, Timan-Pechora province.
Key words: Devonian/Carboniferous boundary, Timan-Pechora Province, conodonts, foraminifers, cyclostratigraphy, biostratigraphy, palaeomagnitology.

New data about the size, shape, composition and structural features of the Devonian organogenic complex (Kara Silova-Yakha interfluve, southeastern Pai-Khoi) are presented. The interpretation of these features is related together with reconstruction of genesis history of this organogenic complex, under the influence of the transgressive-regressive phases of the paleobasin evolution. The study results can be used in geological mapping and in core analysis of wells of the Pre-Urals Trough, where prospective hydrocarbon reservoirs are related to the brecciated aprons, produced by crushing and fracturing of such organogenic structures.

pdf Upper Devonian - Lower Carboniferous key sequence on the Talota river, Timan-Pechora province - results of lithologic, biostratigraphic and paleomagnetic researches
The results of complex studying the Upper Devonian - Lower Carboniferous key sequence on the Talota river (north of the Vashutkino-Talota zone of overthrusts, Timan-Pechora province) are presented. The tectonic twinning of the sequence on the zone of overthrusts is proved by biostratigraphy data. The parautochthonous and allochthonous parts of the sequence are dated by foraminifera and conodonts. The first part contains Early Famenian-Late Visean deposits, the second part - Late Famenian-Serpukhovsk deposits. Breaks in sedimentations are established in the Lower Tournaisian and Lower Visean. The presence of an ancient secondary prefolded component of magnetization, confined to the definite parts of the sequence and caused by tectonic and hypergene processes, is established. The direction of this magnetization allowed reconstructing the prefolded (Middle Paleozoic) position of the allochthone and parautochthone.
