Strike-slip related tectogenesis and structure-forming flow of crustal masses of the Asia-Pacific transition zone

Research subject. This study was aimed at examining the strike-slip related tectogenesis of the Asia-Pacific transition zone (APTZ).Materials and methods. The research was based on the materials collected by the author during long-term fieldwork across the territories of Primorye, Khabarovsk Krai and, partly,Vietnam. Extensive materials on the topic of the APTZ tectogenesis published by researchers fromRussia,China andJapan were analysed. Investigations involved the study of structural and kinematic assemblages representing the forms, directions and time of crustal mass flows under the strike-slip related tectogenesis of the East Asian global strike-slip fault zone (EAGSSFZ).Results. The EAGSSFZ consists of three transit strike-slip fault systems (zones) playing the role of the APTZ basic deep fault structures. Its master system (MS) is NNE (25–30°) trending longitudinally to theAsia edge. The MS is bordered by diagonal NE 50–70° trending near-continental and meridional near-oceanic EAGSSFZ systems. The MS controls the East Asian volcano-plutonic belt (EAVPB), demarcating the APTZ into internal (near-continental) and external (near-oceanic) zones. Two stages of the strike-slip related tectogenesis were established: orogenic-constructive (Jurassic–to–Late-Cretaceous) and riftogenic-destructive (Late Cretaceous–to–Cenozoic). The riftogenic destruction broke the previously formed orogenic foldedthrust structures, thus causing the EAVPB magmatic succession from intracrustal intrusions (Early Cretaceous) to volcanics (Late-Cretaceous-to-Cenozoic). An increase in the crustal destruction during the end of Cretaceous to Cenozoic resulted in the formation of epicontinental sedimentary basins and deep-sea riftogenic depressions of marginal seas. The structure-forming flow of the APTZ crustal masses occurred in the SSW 180–250° direction being opposite and obliquely opposite towards the NNW subduction direction of oceanic plates.Conclusion. The kinematic disconformity as well as the coincidence of the continental crust flow (plate flows) with the direction of inertial-and-equator-oriented forces allowed the author to determine the structuring of the transition zone as a process independent of the geodynamics of oceanic plates and subordinate to the rotational geodynamics of the non-uniformly rotating Earth.

Tourmaline from the Solnechnoe tin deposit, Khabarovsk Krai, Russia

AbstractTourmaline from the Solnechnoe hydrothermal granitoid-related tin deposit in the Khabarovsk Krai, Russian Far East has been studied with electron microprobe, infrared and Mössbauer spectroscopy. Tourmaline formed in three distinct stages with different types of chemical substitution. Tourmaline from the first unmineralised stage is classified as dravite or schorl, which could be enriched locally in Ca, the X-site vacancy and F. This tourmaline is characterised by the Fe ↔ Mg and X vacancy + Al ↔ Na + Fe substitutions. The second, molybdenum-stage tourmaline, is schorl–dravite and fluor-schorl–fluor-dravite enriched in Ca, and a few compositions belong to the calcic group. The predominant substitution is Ca + Mg ↔ Na + Al. The third, tin-stage tourmaline, is classified as schorl–dravite with some tourmalines being fluor-schorl, oxy-schorl, foitite and magnesio-foitite. The tin-stage tourmaline is characterised by the substitutions Fe2+ ↔ Mg, Altot + O2– ↔ Fe2+ + OH–, and Fe3+ ↔ Altot. An increase of the Fe3+/Fetot value from 3–9% in the molybdenum stage to 12–16% in the tin-stage tourmalines indicates an increase in oxidation potential, which possibly contributed to cassiterite deposition. Comparison of tourmalines from greisen, porphyry and intrusion-related tin deposits worldwide shows they differ in primary chemical substitutions so can be characterised by this mechanism. The Fe3+/Fetot value in tourmaline also appears to be one of the indications for the tin deposit type. The Fe3+/Fetot value increases from <10% in greisen tourmaline through 15% in tourmaline from intrusion-related deposits to 20% in tourmaline from porphyry deposits.

Key ornithological territories in western Priokhotye

The results of studying the current state of the habitats of waterfowls and semiaquatic birds in the western part of the coast of the Sea of Okhotsk are reviewed. These habitats are of crucial importance for the reproduction of the birds, as well as for their massive migratory concentrations on the East Asian-Australian migration route in the summer-autumn period. A description of the natural conditions of these territories is provided and the most valuable biotopes are identified, including drying zones rich in marine invertebrates, waterlogged coastal grass fields and moss bogs with karst lakes. Especially significant clusters of birds are formed in the large sea bays – Shchastya, Nikolaya, Ulbanskii, Konstantin, Tugurskii Bays, Udskaya guba, on the Mukhtel Lake, and in the Amur liman. The state of these territories is currently considered as satisfactory, but nonetheless there are certain threats for the ornithologic fauna and bird population. We propose measures for the conservation of birds at the “Okhotsk section” of the East Asian-Australian migration route. We also suggest to organize wetlands of regional significance “Nikolaya, Ulbanskii and Konstantin Bays” in Tuguro-Chumikanskii district and the natural park “Shchastya Bay” in Nikolaevskii district of Khabarovsk Krai.

Phylogenetic analysis and distribution of far eastern tick-borne encephalitis virus subtype (Flaviridae, Flavirus, TBEV-FE) from Asia.

The purpose of the work - revision and comparative analysis of data on complete genomes sequences of the Far Eastern subtype of TBE virus strains distributed in the Asian part of Eurasian continent. The data on the complete genomes of 84 strains of TBEV isolated in Asia were used; phylogenetic analysis was performed. it was shown that variants of the TBEV of the Far Eastern subtype are circulating here and form three separate clusters (Sofjin, Senzhang- и Shkotovo-like strains). Sofjin strain (Sofjin-1953, Sofjin-Chumakov, Sofjin-KSY) was considered to be the reference for Far Eastern TBE virus subtype strains and a cluster of Sofjin-like strains. Sofjin-like strains were not found in China and Japan, but widely distributed throughout the area of Primorsky and Khabarovsk krai. The group of Senzhang-like strains was distributed in China, Eastern Siberia, Khabarovsk krai and northern Primorsky krai, but was not found in Japan (Hokkaido). According to molecular genetic characteristics the youngest and more genetically homogeneous group was the Shkotovo-like strains, isolated in the southern part of Primorsky krai, however not found on Hokkaido Island (Japan). revision of the complete genome characteristics of TBEV strains revealed the features of micro-evolutionary process of viral populations in the Asian part of Eurasia, show the individual affection of strains to certain territories, as well as detect random finds of such strains in the territories of other natural foci.

К биологии Pararctia lapponica lemniscata (Stichel, 1911) (Lepidoptera, Erebidae, Arctiinae) в Северном Приамурье

For the first time certain biological features of the rare Tigermoths taxon Pararctia lapponica lemniscata (Stichel, 1911) (Lepidoptera, Erebidae, Arctiinae) are presented based on the research from the Bureinsky Nature Reserve (Russia, Khabarovsk Krai), where the taxon’s most southeastern habitats are located. Their preferred habitats are mountain larch forests at altitudes of 900–1400 m above sea level, where Sphagnum mosses, Vaccinium vitis-idaea, Rubus chamaemorus and R. arcticus prevail in the lower layer of vegetation. Adult moths appear only in even years, and are active in the daytime with the flight period from June 20 to July 10. The morphology of larvae from first to sixth instars has been studied for the first time. Sixth instar larvae have a black shiny head and a blackgray body with a row of black warts bearing tufts of long black (located only on the dorsal side) and short light hairs along each segment. They differ from the larvae of the nominative subspecies by the absence of polymorphism, and in senior instars light hairs prevail on the body. The number of light hairs increases with each subsequent instar. In their appearance, the larvae P. l. lemniscata are most similar to the larvae of the western North American species Pararctia yarrowii (Stretch, [1874]).

Demographic development of Khabarovsk krai: problems and prospects

Currently, the socio-economic development of the country, any of its subjects is closely linked to the dynamics of demographic processes. The paper provides a traditional analysis of statistical data on the formation of the population of Khabarovsk krai, shows the current distribution of the population of the region on its territory. The study presents the results of the analysis of the processes of natural population movement and shows the role of migration flows (intraregional, interregional and international) in the formation of the dynamics, quantitative and qualitative characteristics of the population of Khabarovsk krai in comparison with the general Far East indicators. The paper identifies the main areas of migration attraction of the population of Khabarovsk krai. There is shown the dynamics of the population of Khabarovsk krai in comparison with other subjects of the Far East. The analysis of the natural reproduction of the population in Khabarovsk krai, presented in the paper, shows the dynamics of fertility and mortality in the region and their opportunities for formation of the demographic potential in the future. The article discusses the current and prospective age structure of the population of Khabarovsk krai, compares it with similar indicators for the Far East region as a whole. Analysis of the transformation of the population structure by age revealed the situation with the reduction of labor potential, which entails the necessity to attract labor using interregional and external migration. On the basis of the established trends in the dynamics of the population, an assumption is made about the possible risks of achieving the indicators provided for by the Concept of demographic policy in the Far East of Russia. The prospective population of Khabarovsk krai is offered for consideration in two variants, the need for implementation of the task to secure population is substantiated.

Grain-Size Composition of Bottom Sediments of the Simmy River in the Bolon Nature Reserve

The composition of bottom sediments in the Simmy River (the Amur River tributary, the Bolon Nature Reserve, Khabarovsk krai, Russia) was studied using laser diffractometry, sedimentation analysis, and electron microscopy. It was found that the grain-size composition of sediments from the area treated was mainly constituted by small-size grains and characterized by the accumulation of fine sand which conformed to lacustrine–alluvial genesis of the territory. The sediments in the near-mouth area were mainly formed by particulate alluvium with prevailing silty fraction. The definitive effect on the composition of sediments is exerted by hydrological conditions of Lake Bolon receiving the riverine waters: the variations in the lake water level conform to those in the Amur River. It was shown that the coagulation and precipitation of suspended solids at low content of organic matter (below 1%) resulted in the appearance of volume-aggregated dense and viscous sediments. A higher content of organic matter (>6% in the Kirpu tributary of the Simmy River) caused the “nodal” differentiation of volume-aggregated spatial structures to form porous microaggregates.

The new locality is situated in the extreme southeastern part of this region (3 km W Kundur village, Khingan Nature Reserve), in 308 – 420 km north-west of previously known habitats in the south of the Khabarovsk Krai. Overwiew of the distribution of S. caudata in Russia is provided.

First Findings of Early Cretaceous Foraminifera in the Lower Stream of Amur River, Khabarovsk Krai

In southeastern Khabarovsk krai, in the basin of the Tumnin River, the foraminifera complex containing the characteristic species Ammosiphonia beresoviensis (Bulatova), represented by exclusively agglutinated shells, is revealed for the first time in sections of Albian deposits. In terms of composition and structure, the complex is closest to the associations widespread in the Albian in the Arctic paleogeographic zone. It differs from the coeval assemblages of Sakhalin and Japan in the absence of warm-water species.

Mass Media Influence on the Population of the Khabarovsk Krai

The article presents the sociological research results on the attitude of the population of the Khabarovsk Krai to regional mass media, in particular, to the TV channel “Gubernia”. The research objectives are to form a socio-demographic image of the audience of the regional mass media, to study the attitude of the people to the quality of the information content of the regional mass media, and to find out the broadcasting needs of the people who are viewers of the regional TV channel “Gubernia”.As a result of the research, it is concluded that there is no marked preference to the TV channel “Gubernia” according to the list of interests of the people of the Khabarovsk Krai. Informative and news broadcasts are among the genre preferences of viewers of all ages and genders. The study showed that the largest audience group is respondents aged 60 and above. The smallest group is young people under 30 years old.According to the research the TV channel “Gubernia” is more in demand among the inhabitants of the provincial municipalities of the Khabarovsk Krai than among the residents of large cities. This can be explained, on the one hand, by the peculiarities of the information space of cities, and on the other hand, the sex and age characteristics of the regional provinces.

Support for regional export activities (cases of regions leaders in growth of export quota)

Foreign trade activity has a strong influence on the socio-economic development of the country. In turn, each of the constituent entities of the Russian Federation contributes, in accordance with the specifics of its location, existing on the territory of the natural resource potential. Due to the fact that the role of the regions in the implementation of the development strategy of the country’s foreign trade is increasing, it is necessary to investigate the problems of foreign trade regulation in order to achieve the required results. To assess the effectiveness of foreign policy conducted, the ranking of all Russian regions for 2010 – 2016 was carried out. in terms of the openness of the economy and the contribution of exports to the size of the gross regional product is estimated. The study analyzed the export activities of the leading regions in the growth of export quotas. Existing measures of state support of foreign trade in the Republic of Buryatia, Magadan region, Kamchatka, Primorsky and Khabarovsk Krai, Orenburg, Rostov, Arkhangelsk, Vologda, Murmansk and Kemerovo regions are considered. The article discusses the impact of government measures to support exports on regional development and suggests ways to adjust them. The study is based on general scientific methods of comparison, analysis and synthesis. As an information base, we used statistical data from state statistical bodies, a strategy for the socio-economic development of regions, and official data from the sites of regional state executive bodies.

Geochemistry and Conditions of the Formation of the Ulsk Thermal Spring (Coasts of the Sea of Okhotsk, Khabarovsk Krai)

The report presents original data on the isotope and chemical composition of the nitric thermal, cold underground, and surface natural waters, along with the water-enclosing rocks, of the Ulsk occurrence of thermal mineral waters (coasts of the Sea of Okhotsk, Khabarovsk krai). The data on the concentrations of oxygen and nitrogen isotopes and rare-earth elements, as well as on the volume activity of radon, in the treated underground and surface waters are obtained for the first time. Based on the data of automated monitoring of the physical parameters, the hydrogeological characteristics of the thermal waters are determined and the balneal properties are evaluated. The results obtained show the atmospheric origin of the nitric thermal waters of the Ulsk spring; however, the indicative chemical elements occurring in the considered waters represent the effects of deep-seated high-temperature processes as well. It is found that the waters warmed to 31°C within fractured Paleocene granites do not show significant variations of temperature, and the chemical composition varies exclusively under the interaction with the water-enclosing rocks. The profiles of the distribution of rare-earth elements (REEs) in the thermal waters represent the REE distribution in the water-enclosing granitoids and point to the limitation of the thermal water circulation with the area of the occurrence of the Paleocene granites of the Bekchi–Ul Massif. The temperature of the deep-seated reservoir measured by geothermometers was 80°C or below, which may indicate a depth of water circulation of 1–2 km or less.

The Depth Distribution of Dominant Species of Macrophytes in the Northwestern Part of the Tatar Strait

This paper investigates the depth distribution patterns of bottom vegetation dominants in the western Tatar Strait (within Khabarovsk Krai). Materials were collected during SCUBA diving surveys performed by the Khabarovsk Branch of the Pacific Research Fisheries Center. The vegetation cover, in the presence of suitable bottom substrates, is formed to depths of 18–22 m and is replaced below by sparse settlements. The abundance indices of most of the dominant species remain relatively stable within depths of 2–20 m. Their ecological optima, as a rule, occur at depths of 2–6 m with increased hydrodynamics. A scheme of the vertical division of vegetation in the area is proposed that corresponds to the results of previous studies on phytal zoning. The location of vegetation horizons and strata is not different from those previously identified, while their boundaries are blurred and correspond to the continuous live cover distribution.
