The article considers various types of non-anticlinal traps of the Yamal Peninsula of Western Siberia. The task is to establish the features of their formation and structure. Gas and gas condensate deposits were allocated in the Akhskian formation of the Neocomian section, associated with wedge-shaped traps (Bovanenkovsky, Kharasaveysky fields). This type of lithologically-shielded traps was formed due to clastic material entering the territory of the Yamal Peninsula from the East Siberian Platform, the Yenisei Ridge (from the east) and the Ural Mountains (from the west). Sand and clay material accumulated along the path of underwater hills, where wedging zones formed. Traps of various types are developed in the Jurassic deposits of the region. Traps of tectonically shielded type are formed in areas of the active influence of discontinuous disturbances on the structure of the section (for example, on the Nurminsky Swell). Lithologically-shielded traps are formed on the slopes of the erosive remnants of the paleorelief in zones of terrigenous horizons wedging. Such traps are also formed in zones of their screening by the surface of the pre-Cretaceous erosion. The considered examples made it possible to establish the confinement of various types of traps to the sediment section and their distribution over the area of ​​the Yamal region.

The results of studying the mineralogy of metamorphic schists from the Pre-Jurassic base of the Arctic part of the West Siberian plate are presented. The accessory and ore mineralization of schists from the Zapadno-Yarotinsky license area located in the southern part of the Yamal Peninsula is studied. The schists was uncovered by the Zapadno-Yarotinskaya No. 300 well at a depth of 2762 m. Above the section, the metamorphic rocks are overlain by a young Meso-Cenozoic cover. The schists are mainly composed of quartz, plagioclase (albite), carbonates (dolomite and siderite), mica (muscovite) and chlorite (donbassite). The discovered accessory and ore minerals in the metamorphic schists of the Zapadno-Yarotinsky area can be divided into two groups. The first group includes minerals that were formed during the metamorphism of schists, or were preserved as detrital matter. These minerals include zircon, fluorapatite, and rutile as the most stable compounds. The remaining mineralization (pyrite, sphalerite, chalcopyrite, cubanite, galena, cobaltite, barite, xenotime-(Y), goyazite, synchysite-(Nd), native silver and copper) is clearly secondary and was formed as a result of superimposed metasomatic processes. Judging from the described mineralogy, the schists underwent changes as a result of superimposed propyllitization. The temperature range of this process is determined by the formation of cubanite in association with chalcopyrite at a temperature of 200-210 оС.

Dutch cartographer and merchant Isaac Massa’s activity in Muscovy at the beginning of the XVII century was studied. The information about the origin of the map of the northern coast of Russia, the Yamal Peninsula and the Gulf of Ob in the first place was analysed. In Russian historical publications Massa is considered to be a foreign agent who took a hand in the transfer of confidential information on the cartography of Muscovy to the Netherlands. At the same time, the selection of historical facts and documents and the action logic of Massa suggests otherwise. Massa was certainly one of the first who participated in creating the latest maps of the Arctic Ocean coast and the general map of Russia, and he did it with the direct support of influential Russian circles and in the interests of Russia. We assume that, аt the initial stage of his activity in Russia, Massa represented the interests of the first clan of merchants, the Stroganovs, wishing to include Siberia into the sphere of their direct influence. The material for the preparation of the drawing of Yamal, which was the first image of the peninsula on a map, was probably obtained from the Arkhangelsk coast-dwellers (pomors), who went by sea to trade in their trading station Mangazeya. The assumption that Massa secretly gained access to the so-called Book of the Great Drawing (Kniga Bol’shomu chertezhu) does not stand up to criticism. Massa left Muscovy in the spring of 1609, quite legally taking with him the latest materials on the cartography of Russia and with the task to publish them in the west as soon as possible. Published maps, the actual has consolidated the priority of Russia for the possession of the coast of Western Siberia.

The article is devoted to the four-year (2017–2020) monitoring of gas emissions from the bottom of the Seyakha Crater, located in the central part of the Yamal Peninsula (north of Western Siberia). The crater was formed on 28 June 2017 due to a powerful blowout, self-ignition and explosion of gas (mainly methane) at the site of a heaving mound in the river channel. On the basis of a comprehensive analysis of expeditionary geological and geophysical data (a set of geophysical equipment, including echo sounders and GPR was used) and remote sensing data (from space and with the use of UAVs), the continuing nature of the gas emissions from the bottom of the crater was proven. It was revealed that the area of gas seeps in 2019 and 2020 increased by about 10 times compared to 2017 and 2018. Gas in the cryolithosphere of the Arctic exists in free and hydrated states, has a predominantly methane composition, whereas this methane is of a biochemical, thermogenic and/or mixed type. It was concluded that the cryolithosphere of Yamal has a high level of gas saturation and is an almost inexhaustible unconventional source of energy resources for the serving of local needs.

Relevance of the work. The Arctic part of the West Siberian megabasin is the main source of oil and gas in Russia, therefore, the study of the geological structure of this region is extremely important. Recently, Russia has lodged an application to extend its territory in the Arctic Ocean along the ridges that stretch from the continental shelf. Unfortunately, at the same time, we know little about the geological structure of the Arctic in the region of Western Siberia, where the thickness of the sedimentary cover is very high (about 3–4 km), therefore, the study of the basement of the Yamal Peninsula seems to be extremely urgent. The purpose of this work is mineralogical, petrological and geochemical study of dolerites from the pre-Jurassic basement of the Bovanenkovskaya area (well No. 114) within the territory of the gas condensate field of the same name, located in the western part of the Yamal Peninsula. Scope of the work. This work can be useful in constructing geological maps of the pre-Jurassic basement of the Yamal Peninsula. Results and conclusions. We have studied the mineralogical and geochemical features of dolerites from the pre-Jurassic basement of the Bovanenkovskaya area (well No. 114, sampling depth – 3210 m) of the West Siberian megabasin. The mineralogy of the rocks is represented by augite, diopside, albite, magnesian chamosite, ferrous hornblende, calcite, siderite, dolomite, anorthoclase, grossular, zeolite (gmelenite-K), pyrite, chalcopyrite, and rare lead chloride – cotunnite. The rocks underwent minor transformations in the conditions of the lower greenschist metamorphism, as well as secondary alterations in the form of superimposed propylitization. As a result of this low-temperature metasomatic process, zeolite, carbonate (calcite, dolomite, and siderite) and sulfide mineralization composed of pyrite and chalcopyrite, as well as cotunnite, which apparently replaced the dissemination of galena, were formed in the rock. Judging by geological position of the region, these dolerites are most likely formed at shallow depths during continental rifting. Remelting of the Paleozoic island arc substrate during the Early Triassic rifting and volcanism provided some closeness to the island arc trend in the geochemical features of these rift volcanics.

Two rare species of diatom algae, Chamaepinnularia circumborealis and Neidiopsis wulffii, are recorded in water courses and waterbodies in the Yamal Peninsula (Western Siberia, 69°16′2.8″–70°33′53.6″ N, 68°04′10.3″–68°9′57.46″ E). New data on their ecology and distribution are provided. A SEM study of these species has shown their broader variability in diagnostic characters (valve length and width, number of striae in 10 μm, shape of valve, raphe and central area, structure of striae) in comparison with published data. Descriptions of Chamaepinnularia circumborealis and Neidiopsis wulffii are refined. Their differentiation from morphologically similar species is discussed.

Artikkelissa tarkastellaan, voisivatko vuonna 2016 Jamalin niemimaalla luoteis-Siperiassa ilmenneet pernaruttotapaukset haastaa Venäjällä vallitsevaa diskurssia, jossa mahdollisesti pernaruton ilmenemisen taustalla oleva ilmastonmuutoksen ongelma sivuutetaan. Artikkelissa pohditaan, miten mahdollinen haaste vallitsevalle diskurssille ilmenisi. Tutkimus perustuu rajattuun otokseen kansallisen ja paikallisen tason mediasisältöjä, joissa pernarutto liitettiin ilmastonmuutokseen. Analyysi hyödyntää poststrukturalistisen diskurssiteorian oletuksia sekä dislokaation ja diskursiivisen logiikan käsitteitä ja kohdistuu talouskehityksen ja ympäristön muutoksen suhteeseen alueella, joka on yhtä aikaa keskeinen Venäjän fossiilitaloudelle sekä haavoittuva ilmastonmuutoksen vaikutuksille. Tulokset osoittavat esteitä ja mahdollisuuksia ilmasto-oikeudenmukaisuuden toteutumiselle tässä viitekehyksessä.    Poststructuralist discourse on climate justice in the Russian North This study uses the case of the 2016 anthrax outbreak on the Yamal peninsula in north-western Siberia to discuss whether and how the incident could challenge the dominant discourse in Russia that neglects the problem of climate change – a potential cause of the outbreak. The study draws on a small sample of media materials that linked the incident to climate change on the national and regional levels. The analysis follows the premises of poststructuralist discourse theory and the concepts of dislocation and discursive logics to unpack the intricate relationships between the issues of economic development and environmental change in a region that is at once central to Russia’s fossil fuel economy and most vulnerable to the effects of climate change. The results point to the obstacles and opportunities for climate justice discourse in this context.

Relevance of the work. Comprehensive studies of the geology of the Arctic part of Western Siberia are very important for the search for oil and gas in this vast but understudied territory. At present, unfortunately, we know little about the geological structure of the Arctic in the region of Western Siberia, where the sedimentary cover is mainly investigated (the thickness of which is about 3–4 km) and only a few wells are drilled to the foundation. Therefore, a comprehensive study of core samples from this little-studied territory seems extremely relevant. The purpose of the work is a detailed description of the mineralogy and petro-geochemical features of garnetquartz-chlorite-muscovite schists from the well Verkhnerechenskaya no. 2 from the foundation Arctic part of the West Siberian megasbasin. Scope of application of work. This work can be useful in constructing geological maps of the pre-Jurassic foundation of the Yamal Peninsula. Results of work and conclusions. Mineralogy has been studied in detail and the trace element composition of garnetquartz-chlorite-muscovite schists is obtained. The mineral composition of the rocks is as follows: almandine, muscovite, quartz, chamosite, calcite, albite, rutile, titanite, fluorapatite, zircon, xenotime-(Y) and pyrite. The progressive zonality in the almandine is determined, which is confirmed by the calculated data of metapelite formation temperature, progressive metamorphism. Distribution of rare, scattered and REE in the studied rocks is characteristic of metamorphic schists from the foundation of the Urals part of the West Siberian megasbasin, which compel the framing of monzodiorite-granite massifs of Shaimsko-Kuznetsov meganticlinorium of Western Siberia. Probably, the metapelites studied are the result of warming up the thickness of sedimentary rocks with granite intrusion located in the vicinity of Verkhnerechenskaya area. Later, the rocks underwent propylitization with the formation of secondary carbonate and pyrite.

Ostracods are an effective tool for dissecting and correlating Mesozoic sedimentary strata in closed areas. However, the degree of geologic certainty of ostracods from the marine Lower-Middle Jurassic deposits of West Siberia is very weak. The paper presents the results of monographic and biostratigraphic studies of the Jurassic ostracod complexes of the Yamal Peninsula. 5 stratigraphically important species are described, and images are given for 6 forms. The biostratigraphic division of the Lower and Middle Jurassic of West Siberia by ostracods is substantiated. In the Pliensbachian – Bajocian, a sequence of 6 biostratons was traced by ostracods in the rank of layers with characteristic species: layers with Ogmoconcha longula; with Camptocythere (C.) mandelstami; with Camptocythere (C.) foveolata (established by the author); with Camptocythere (C.) nordvikensis; with Camptocythere (A.) spinulosa; with Camptocythere (A.) arangastachiensis. The West Siberian ostracod biostratons are compared with divisions of the zonal scale for the ostracods of East Siberia, which was developed on natural outcrops of the Jurassic and is сorrelated to the scales for ammonites and other groups of macro- and microfauna.
