|Ydzhid Anticline Late Famennian (south of Pechora-Kozhva Uplift, Pechora Plate)|
|Study of a number of sections in the south-western part of the Lyzha-Kyrtayol Swell (south of the Pechora-Kozhva Uplift) allow elaborating conodont-based biostratigraphy scale and improving lithological description of the lower part of the Nyumylga level. This stratigraphic interval corresponds to the upper unit of the Kamenka Formation represented by shallow-water bitumen bearing carbonates. The study allows improving information on geology of Ydzhid Anticline and local stratigraphic chart of the Upper Devonian.
Keywords: Upper Devonian, biostratigraphy, Nyumylga level, Kamenka Formation, Ydzhid Anticline, Pechora Plate.

|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.

|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.

|Perspectives of application of isotope-stratigraphy (δ13Ccarb) for correlation of the Upper Devonian – Carboniferous interval of the east of Timan-Pechora Province|
|Perspectives of application of the δ13Ccarb - based isotope stratigraphy for regional stratigraphy of the Timan-Pechora Province are considered. Global shifts in δ13Ccarb value, which promise reliable stratigraphical levels, are selected: positive shifts at the Middle/Upper Devonian boundary, in the middle and upper Frasnian, terminal Famennian, upper Tournaisian, near the Visean/Serpukhovian boundary, and in the lower part of the Bashkirian. Some of these shifts had been detected in the Timan-Pechora sequences earlier and are dated with biostratigraphy. The main task of the future researches is obtaining reliable information on primary variations of δ13Ccarb in the sequences of the regional strata.
Keywords: isotope stratigraphy, Upper Devonian, Carboniferous, Timan-Pechora Province.

|Taphonomy of conodont elements in the environments of shallow-water Carbonate shelf – the Lower Carboniferous of the eastern part of Timan-Pechora basin as example|
|Taphonomical peculiarities of conodont elements in the shallow-water clayey-carbonate deposits are considered. All the lithological types demonstrate traces of hydrodynamic sorting of conodont elements, but diachronous reworking is absent. Significant abundance of the conodont elements providing reliable biostratigraphical interpretation is characteristic of mudstones, wackestones, and pack-wackestones; grainstone samples are barren as a rule.

|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.

|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.

|Structure and formation conditions of Frasnian section, northwest Pay-Khoy|
|The Frasnian of the northern part of the Pay-Khoy carbonate parautochton is represented by Pyrkov Formation. The formation disconformally overlays Lower and probably Middle Devonian, and corresponds to beginning of the Late Devonian – Tournaisian cycle of sedimentation. The Pyrkov Formation is composed of the six facial types, which correspond to wide spectrum of environment – from extremely shallow-water up to deep water. The stratigraphical sequence of the facial types allows us reconstructing the appearance of the isolated carbonate platform (shoal) in the late Frasnian. Local microbial and algal bioherms are characteristic for the late Frasnian. The bioherms were partly eroded during the Frasnian/Famennian regression.

|Sedimentation model of the transitional zone from the Elets to Lemva formation belts (Devonian-Carboniferous boundary, Cis-Polar Urals)|
|Shoal and bioherm deposits of the transitional zone form the the Elets formation belt to the Lemva formation belt are considered as perspective object for oil and gas prospecting. Study of the sections in the basins of the Kozhym and Lemva rivers allows us to reconstruct environments in the shoal belt in the Devonian/Carboniferous boundary interval. Area of deep erosion (up to the Middle Famennian) is reconstructed in the Early Tournaisian. Usually the bioherms are considered as having great potential as natural reservoirs for the oil and gas in the Upper Devonian – Lower Carboniferous. Study of the porosity of the rocks of the shoal complex allows supposing debris fans of the frontal and back shoal slopes as promising natural reservoirs for the oil and gas. Shoal and bioherm rocks demonstrate lower porosity.
Key words: Cis-Polar Urals, Upper Devonian, Lower Carboniferous, environments, shoal, debris fans, porosity.

|The article deals with the Devonian/Carboniferous boundary in the shallow-water sequence (the Kamenka River section as example) on the basis of cyclostratigraphy (maximum of regression) controlled by biostratigraphical data (conodonts and foraminifers). Facial control on the foraminifer and conodont associations is considered. Dependence of the magnetic successibility 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.

|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.

|Paleogeographic occurrence and stratigraphic significance of the Gondolelloides genus representatives (conodonts, Late Paleozoic)|
|Conodonts are of great importance in the biostratigraphy of Lower Permian deposits.
is one of the conodont genera typical for the Asselian-Sakmarian interval, Northern cool-water province. At present, the representatives of this genus are found in the different-phase deposits in nine sequences in Northern America, in two sequences in the Novaya Zemlya, in one well in the east of the Timan-Pechora province, in one sequence in Polyarny Urals and in two sequences in Southern Urals. All these finds of the
representatives are confined to the Upper Carbonaceous Upper Gzhelian stage in southern Urals and to the Upper Asselian - Lower Sakmarian stage in other regions. It is not improbable that the center of
origin was located in the southern part of the Paleourals basin from which they subsequently spread in more northern and western regions including the eastern shelves of Panthalassa. The above data show that using the representatives of the
genus for interregional and global correlations is not reliable. However
may be used for local and intrabasin correlations.

|Biostratigraphic subdivisions analysisof the Upper Devonian - Perm by conodonts|
|The factors affecting the level of delineation and units border traceability by conodonts in the Upper Devonian-Permian are being discussed. Detailed zonal schemes based on the inhabitants of the deep water are severely restricted by a relatively limited facial range (at best - deposits of deep shelf and continental slope of warm basins), although they are found in large areas within this facies range. Zonal schemes based on the inhabitants of shallow water are not only facially limited (sediments of shallow water shelf and inner seas), but also paleogeographically limited. The isochronism of their borders still remains in most cases but only within the whole paleobasin or its part. The ways of problems solution of inter-facies and interterritorial correlations by conodonts have been considered.
