pdf Organic geochemistry of the Frasnian sections of the northern Chernyshev Ridge area (Timan-Pechora Basin)
For the first time, data are presented on the geochemistry of organic matter belonging to the Darshor stream section (northern part of the Chernyshev Ridge). Lithologically studied section is represented by siliceous-clay-carbonate rocks with interbedding of fine-grained dark gray to black bituminous limestone. The biostratigraphical data correspond to the upper part of the Sargayev - the lower reaches of the Domanik level of the Frasnian age. The distribution of saturated and aromatic hydrocarbon biomarkers, the isotopic composition of carbon kerogen, bitumoid and its fractions are characteristic for the organic matter of the Domanik Formation of the Timan-Pechora petroleum bearing basin.
The data of the conodonts color indexes as well as a number of geochemical parameters indicate the degree of the middle mesocatagenesis (“oil window”). The studied deposits have a significant generation potential characteristic for the Domanik rocks - Timan-Pechora petroleum basin at these stage of catagenesis.

Keywords: organic matter, Domanik Formation, mesocatagenesis, Chernyshev Ridge, Timan-Pechora petroleum bearing basin.

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  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  Famennian organic matter of the southern part of the Chernyshev Ridge (Iz’yayol River section)
The article presents new data on the stratigraphy and formation conditions of the Famennian siliceous-clayey-carbonate section and about the origin and catagenesis of the belonging organic matter of the Chernyshev Ridge on the Iz’yayol River. The investigated rocks, according to the existing paleofacial reconstructions and new lithological and biostratigraphic (conodonts) data, were formed in the deep-water shelf environment of the western slope of the Kozhym intra-shelf palaeodepression in the crepida and marginifera phases. Hydrocarbons generation potential of the deposits is almost completely realized. The new data are important for understanding of the hydrocarbon generation processes, when realizing the potential of source rocks which had entered in the oil window.

Keywords: organic matter, Famennian, siliceous-clayey-carbonate deposits, Chernyshev Ridge.

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.
