Five macerals were identified that compose the organic matter of the studied formation: “standard” bituminite, “atypical” bituminite, radiolarian organic matter, alginite and vitrinite, as well as bitumen and bitumen films, which are the products of the original organic matter transformation. The metamorphosis in macerals during catagenesis is described, and the order of their entry into the generation phase is established. It has been shown that alginite starts transforming first, then “standard” bituminite, “atypical” bituminite, and the last one is the radiolarian organic matter. The results obtained were confirmed by the laboratory modeling of the further organic matter transformation. New bitumens are formed with different fluorescent properties compared to the initial ones. The results obtained in combination with the study of changes in the composition of both macerals and bitumen can make it possible to assess the contribution of individual organic matter microcomponents to the process of petroleum hydrocarbons generation.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

The heterogeneity of the seabed topography and the presence of islands formed by protrusions of the pre-Jurassic basement led to the formation of the Vogulka strata as a result of the removal of clastic material from the land. At the same time, far from the islands, in relatively calm shallow environments, clayey and glauconite-clayey sediments of the Abalak Formation accumulated. Gravelites and sandstones of the Vogulka strata were formed unevenly. The greatest thickness of these deposits is observed to the west of the central upland. The difference in the thickness of clastic strata on the western and eastern slopes could probably be caused by the specific horseshoe shape of the island and the absence of active currents on the western part of the slope, as well as its greater steepness. The upper member of the Vogulka strata, composed of detrital limestones, is extremely thin (no more than 1 m), and contains numerous unconformities. Probably, these traces of erosion can be indirect evidence of the influence of the Late Oxford regression on the structure of the section, which was previously noted in adjacent territories.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

Dispersed dolomite in situ formed during the maturation of TOC from syngenetic magnesium in the rock matrix increases the void space of the rock, thereby forming an unconventional reservoir filled with autochthonous hydrocarbons and oil components. In the process of TOC maturation and hydrocarbon migration, the TOC components are redistributed in the void space, thereby, the released volume of rocks is filled with stationary resinous asphaltene substances, which sharply reduces the reservoir properties of unconventional reservoirs. As a result, the definition of “organic” porosity includes a broader concept than just the porosity of kerogen. This is a more complex physicochemical process of transformation of the organic matter itself and the redistribution of elements within the formation as a result of the maturation of TOC components and hydrocarbon migration. When assessing the oil and gas potential in the section, we distinguish three groups of rocks: unconventional reservoirs with an increased TOC content and the presence of mobile hydrocarbons; bituminous rocks, in which part of the pore volume is filled with resinous-asphaltene substances and host dense carbonate rocks without organic matter. Also, sporadically developed traditional reservoirs are distinguished throughout the section of the Domanik type of rocks.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.

The relief of the studied territory has an inherited character; it was formed in several stages during the neotectonic stage. The most intense vertical movements occurred at the early phases of the neotectonic stage. At Pleistocene time the intensity of vertical movements decreased significantly. At this time, the modern erosion-denudation forms of relief was formed. At the final stages of neotectonic development (at the end of the Pleistocene — Holocene), there was a slight activation of vertical movements with a changes in the structural plan and the manifestation of NNE stretched structures in the relief, which was reflected in the features of the residual relief. The boundaries of areas with increased residual relief coincide with areas of increased seismicity in the region. A modification of the complex self-similarity parameter PRNS was proposed, the use application of which allowed us to improve the correlation of this parameter with the latest (youngest) movements detected by the morphostructural method. Zones of maximum PRNS values correlate with the areas of greatest relief increment, and zones of it’s minimum correlate with areas the smallest relief increment, or areas of most significant erosion. The results of the analysis of the characteristics of self-similarity of the stream network are mainly comparable with the manifestations of vertical tectonic movements at the final stages of neotectonic development.","PeriodicalId":253271,"journal":{"name":"Moscow University Bulletin.
