M1 formation tectono-structural features and gas-oil potential within Archinskaya area Paleozoic basement (Western Siberia)
- Authors:
- Vladimir B. Belozerov
- Mikhail O. Korovin
Western Siberian Plate basement oil and gas potential evaluation largely depends on structural and stratigraphic complex architecture representation. New modern procedures for seismic data processing, detailed Paleozoic deposits stratigraphic studies and expanded geophysical well logging significantly change the representation of the basement rocks fold-block structure and previously developed hydrocarbon reservoirs models. Detailed studies conducted within the Archinskii uplift showed that Paleozoic sediments form a contrasting folded structure complicated by block tectonics. The significant block displacements amplitude determines the lithological and stratigraphic basement rocks erosional-tectonic surface, while the identified stratigraphic blocks control the oil productivity distribution within the Archinskaya area. The filtration-capacity heterogeneity folded structure of the Paleozoic sediments is reflected in the distribution of hydrocarbon saturation in the well section, forming independent gas, oil, and oil-water zones for the development process. The relationship between anticlinal structural forms of basement rocks to lowered, and synclinal to elevated blocks, determines the necessity to conduct exploration prospecting within younger stratigraphic blocks when assessing the deep Paleozoic oil and gas potential.

Analysing the problems of reproducing the mineral resource base of scarce strategic minerals
The results of studying the scarcity of strategic minerals in the Russian Federation are presented, domestic consumption of which is largely provided by forced imports and/or stored reserves. Relevance of the work is due to aggravation of the geopolitical situation and a growing necessity to meet the demand of national economy for raw materials from own sources. Analysis of the state of mineral resource base of scarce minerals in the Russian Federation was accomplished, problems were identified and prospects for its development were outlined taking into account the domestic demand for scarce minerals, their application areas and the main consumers. Reducing the deficit through the import of foreign raw materials and the development of foreign deposits does not ensure the reproduction of the domestic mineral resource base, independence of the country from imported raw materials as well as additional competitive advantages, economic stability and security. It was ascertained that a major factor holding back the development of the mineral resource base is insufficient implementation of new technological solutions for the use of low-quality ore. Improving the technologies in the industry is relevant for all types of scarce minerals to solve the problem of reproducing their resource base. Taking into account the prospects for the development of the resource base for the minerals under consideration (manganese, uranium, chromium, fluorspar, zirconium, titanium, graphite) requires a set of legal and economic measures aimed at increasing the investment attractiveness of geological exploration for subsoil users at their own expense without attracting public funding. The proposed measures, taking into account the analysis of positive experience of foreign countries, include the development of junior businesses with expansion of the “declarative” principle, the venture capital market, various tax incentives, preferential loans as well as conditions for the development of infrastructure in remote regions. The proposed solution to the problem of scarcity of strategic minerals will make it possible in future to present measures to eliminate the scarcity of certain types of strategic minerals taking into account their specificity.

Vs sustainable development: scenarios for the future
Issues of sustainable development began to concern mankind starting from the 20th century, when mass industrialization and the depletion of natural resource potential contributed to the formulation of environmental issues at one of the leading places in scientific discourse. However, what if the goals of sustainable development would not be achieved to 2030? What other way we can identify for humanity to survive? So, the study is about the problems of studying the understanding of the term “sustainable development”, considering the evolution of the formation of the concept of sustainable development and analyzing the modern goals of sustainable development for attainability. From an analysis of domestic and foreign experience, possible scenarios of the development of mankind are identified (such as 1. Creating an environmental framework, 2. Implementation of sustainable nature management practices in the conditions of natural and man-made objects, 3. Implementation of “geoengineering projects”, 4. Construction of autonomous ecosystems, 5. Space exploration in search of a new planet for life, provided that the goals of sustainable development would not be achieved. It has been established that today probability of achieving all the sustainable development goals by 2030 is too small, and the indicated scenarios require, firstly, the development of science and technology, and secondly, a competent assessment of the value of nature and solving the issue of specifying property rights for natural goods.

Combined 2D inversion of electrotomographic and audio-magnetotellurgic sounding data to solve mining problems
- Authors:
- V. A. Kulikov
- A. E. Kaminskii
- A. G. Yakovlev
Electrical methods of exploration are widely applied in prospecting and estimation of ore mineral resources. It is not always that geoelectrical models obtained in the course of interpretation of different types of electric and electromagnetic sounding are in line with each other. This leads to difficulties in geological interpretation of electrical exploration results. In single cases a geological model can be built that with great precision satisfies data from different electrical explorations, for instance, results of geometric and inductive electromagnetic soundings. For this purpose an algorithm of combined inversion of electrotomographic and audio-megnetotellurgic sounding data has been developed and implemented by A.E.Kaminskii in software ZondRes2D. Advantage of combined inversion has been shown for investigation of sections up till 400-500 m deep on synthetic models and actual field data.

Geological and mathematical model of secondary sulphidisation zone polarizability as a function of oil and gas deposit depth
- Authors:
- O. F. Putikov
- S. A. Ivanov
The differential-normalized method of electrical exploration (DNME), by means of polarization study of the secondary sulphidation zone (depth ~ 0,4-0,6 km), allows making conclusion about existence and parameters of an oil and gas deposit (depth up to ~ 2-5 km). The approximate solution of the system of nonlinear differential equations in partial derivatives for concentration of sulfur-hydrogen and pyrite (polarizability) as the function of oil-gas deposit depth has been received. The results are confirmed by experimental investigations in the North Sea.

On the classification of industrial pegmatites of Northern Karelia and the direction of exploration work on mica
- Authors:
- A. V. Skropyshev
Many researchers have attempted to classify the pegmatite formations of Northern Karelia, but all proposed schemes suffer from a one-sided approach to taking into account the existing geological factors and use only one or two guiding ones, ignoring the rest. Thus, some divide all the pegmatites of the region into mica-bearing and ceramic [1], others classify them by mineral composition [3], others only by shape, and others by shape and the nature of the distribution of mica in the veins. None of the proposed classifications take into account the geological and structural factors characterizing the conditions of formation of industrial pegmatites. For these reasons, the listed classifications of industrial pegmatites of Northern Karelia are almost never used in prospecting and exploration work, as well as in assessing these deposits. The most perfect classification of pegmatites of Northern Karelia should be considered the classification proposed by V.D. Nikitin and P.P. Borovikov, in the compilation of which the author's materials were used. Studies of pegmatites in Northern Karelia conducted in recent years have provided a significant amount of material for determining the conditions of formation of pegmatites and classifying them according to genetic characteristics.

Field accuracy of geophysical observations
- Authors:
- E. M. Kvyatkovskii
He solution of various geological exploration problems by geophysical exploration methods is generally divided into two main operations: 1) the study of the physical field (magnetic, gravitational, etc.), against the background of normal values of which anomalous values, caused by the influence of various geological objects, are more or less clearly distinguished; 2) geological interpretation of the physical field, i.e. decoding (quantitative or qualitative) of anomalous values As a result of these measurements, sometimes quite complex, including in the overwhelming majority of cases elements of mathematical processing, and in some cases interpretation (seismograms, spectrograms), exploration geophysicists will receive for each point where the measurement was made, a certain value of the parameter of the physical field. Based on these values, graphs, contour maps, vector plans, hodographs, etc. can be constructed, which are the main and only material subject to interpretation in the geological sense of the word. However, before proceeding to the interpretation of the obtained graphs, maps, hodographs, etc., it is necessary to have a very clear idea of their reliability, or, in other words, it is necessary to take into account the magnitude of the error made during measurements, which characterizes the field accuracy of observations. Although the field accuracy of observations is not the only factor determining the accuracy of the geological interpretation of results, in a number of cases it plays a very significant role along with other factors (observation network, physical properties of rocks, etc.).

On accelerated spectral quantitative determination of copper in pyrite ores
- Authors:
- V. V. Khokhlov
Thanks to the creation of high-quality domestic equipment for studying minerals and ores, spectral analysis methods are becoming increasingly important both in studying the material composition of deposits, host rocks, mineralization zones, etc., and in quantitatively assessing the content of ore components in them. Spectral analysis is of particular value in field conditions, increasing the efficiency of geological exploration and allowing a preliminary assessment of the objects under study. Experimental studies conducted by us on the material of studying copper pyrite ores allowed us to develop a method for rapid quantitative spectral determination of copper in field conditions without the use of complex additional equipment. Methods of quantitative spectral analysis are based on an unambiguous relationship between the intensity of the spectral lines of elements and the concentration of these elements in the substance under study. This relationship is established by comparing the spectra of samples and standards visually or with a microphotometer by measuring the blackening of the spectral lines.
