Description:    In addition to ophiolites in the structure of the Otrozhnaya sheet, the igneous rocks were established within the Middle Devonian-Lower Carboniferous tuffaceous-terrigenous complex earlier considered to be the cover of the ophiolite association. In order to establish their geodynamic formation setting, the geochemical study of igneous rocks was conducted. The volcanic rocks from the ophiolite complex are similar to MORB; subvolcanic rocks of tuffaceous-terrigenous complex have a suprasubduction origin. An abundance of pyroclastic rocks and the type of sediments allow us to conclude about their formation in an island arc setting. The existence of the Middle Devonian-Lower Carboniferous island arc complex within the Ust’-Belaya Mountains gives rise to continue the Koni-Taigonos arc inside the region and testifies to its subsistence in the Devonian.

Description:    In recent years, much attention has been paid to nontraditional hydrocarbon sources. Today the portion of nontraditional gas in the world extraction is 15% or 450 billion cubic meters, which hat makes up the volume of total gas exports from Russia. As is known, the easy-prospecting oil has been already found. The innovative technologies in geophysics, drilling, and excavation and the increased extraction coefficient expect further development and industrial compliance with these requirements. Based on calculations, the world oil reserves are now one trillion of stock tank barrels and one trillion barrels have been already extracted. The evergrowing demand for energy gives rise to the necessity of searching for and extracting more oil resources, and both these aspects are unique problems. The search for profitable petroleum deposits has become more and more difficult even in the leading companies. The increment of the world resources is a key vital question; therefore, the elaboration of criteria for the discovery of nontraditional deposits take on special significance in the economic respect. The authors are working out a conception that will be a guideline for future finding of the richest oil deposits in active geodynamic zones. For the first time, we suggest the polygenic formation model of the planet’s bituminous belts. Content Type Journal Article Pages 617-621 DOI 10.1134/S1028334X1105031X Authors A. N.

Description:    The results of detailed studies of the January 6, 2006, Balei earthquake ( K p = 13.1, M b = 4.7 [7]), which occurred in an almost aseismic area of the east Trans-Baikal Region, are presented. The focal mechanism and dynamical characteristics of the focus are considered, and the structural-tectonic position of the focus is analyzed. It is supposed that the focus of this seismic event coincides with an activated segment of the northwest-striking Balei-Darasun fault. The maximal observed macroseismic intensity was 5–6 points by the MSK-64 scale (in the town of Baleis). The origination of foci for the earthquake with such intensity and magnitude takes place substantially owing to subhorizontal northeastern compression, the varied-rank block structure of the medium, and low rate values of tectonic motions; on aggregate, all these factors promote the accumulation of stresses in the Earth’s crust. The obtained data can be useful for the purpose of assessment in seismic danger of the region. Content Type Journal Article Pages 552-556 DOI 10.1134/S1028334X11040222 Authors V. I.

Description:    This article-one of the results of a unique expedition of sub ocean manned vehicles “Mir-1” and “Mir-2” on the lake Baikal. The Author of the article took part in 10 dives to depths of up to 1600 meters, during which he for the first time discovered the ancient layers of gravel material. The origin of these layers was associated with wave-cut activity in the early days of filling the lake basin. These underwater terrace-good indicators of a four lap increase in lake level, which corresponds to the stages of melting of continental ice formations in North Asia.

Description:    This paper discusses the prospects of application of the laser deformographs, broadband seismographs, and GPS/GLONASS receivers for the purpose of prediction of a probable crustal earthquake with magnitude 7 at the depth of 20 km by variations of the stress-strain field of the Earth on its surface. The measurement carried out have shown that the application of laser deformographs can solve this problem, while the application of various seismographs and GPS/GLONASS receivers cannot help to do this.

Description:    40 Ar/ 39 Ar isotopic ages of magnesioarfvedsonite (725.9 ± 6.3 myr) and phlogopite (637.6 ± 5.7 myr) from carbonatites of the Penchenga rock complex located in the South Trans Angara segment of the Yenisei Ridge have been determined. Based on this, the formation of the rock complex is associated with the start of the period of Neoproterozoic (725–700 Ma) rifting and alkaline magmatism in the region, the latter being associated with the former. The appearance of zones penetrable for magma of the “disseminated” rifting type is associated with the development of late collision shear dislocations in a consolidated marginal continental crust. The primary melts had a plume nature, but matter from different mantle sources intermixed in the environment of the changing geodynamic regime. The younger age of the mica was apparently caused by partial remelting of carbonatites under the influence of heat and fluids generated during the formation of the adjacent large granite massif of a younger age.

Description:    This paper presents new data on numerous small metallic particles of iron, copper, Fe-Ni, Fe-Ni-Co, and Fe-Cr alloys, magnetite, and aluminosilicate balls of cosmic origin found in the black clay boundary layer between the Cretaceous and Paleogene in the Stevns Klint Section (Denmark). The findings imply that a fall of an asteroid to Earth 65 Ma ago was accompanied with falling of finely dispersed metallic particles of extraterrestrial nature related to the asteroid fragments or to micrometeorites following the asteroid or to the intense supply of cosmic dust. The huge amount of finely dispersed matter that fell to Earth at that time should be considered in further reconstructions of events at the boundary of the Cretaceous and Paleogene.

Description:    The regularities of reaction of the viscous bitumen (maltha) structure when affected by modulated and impulse electromagnetic and acoustic fields via recording of infrared emission spectra are studied. It has been found that characteristic reactions of viscous oil clusters and links between them are located in the THz range for electromagnetic waves and in the MHz range for acoustic actions, which are revealed in absorption and emission spectra. The reaction of the rest (non-THz) part of the infrared spectrum is described on the basis of the physical-mathematical model of the process of a photon-phonon soliton, which causes decrease of emission IR spectrum intensity after microwave action due to fixation of the electromagnetic field by a soliton. The obtained results, which establish selectability of the maltha specimen reaction on spectral composition of the affected radiation, are important for increasing the efficiency of ultrasonic and electromagnetic microwave actions on the productive stratum during application of secondary methods for oil deposit exploration.

Description:    High-precision catalogues containing data on the spatial distribution of earthquake sources associated with several fault zones have been processed. The analysis shows a high degree of spatial localization of seismicity. Most of the events are observed in a narrow zone with a characteristic width of about 100 m. This value is a part of a percent of the fault zone length and corresponds to the upper boundary of estimates concerning the effective fault width, which are made on the basis of data on the characteristic parameters of roughness and waviness of rock discontinuities.

Description:    The intraplate activity within the Siberian Craton in the Phanerozoic is related to continental migration above the hot spot agglomeration compared to the African superplume. The continuity of intraplate activity within this superplume testifies to its age identity to the antipodal to the Rodinian superplume that destroyed the Rodinia supercontinent. This allowed us to conclude that the African superplume has existed for no less than 1 Ga. Because the Rodinian and Pacific superplumes are compared, it may be gathered that superplumes are the most long-lived deep-seated structures of the Earth. Their relation to the formation of supercontinents probably reflects the antiphased activity caused by the thermostating effect and energy accumulation by superplumes when being overlapped by supercontinents. When analyzing the evolution and generation of modern continents, it is necessary to consider both processes related to the plate boundaries and the activity of superplumes determining the intraplate magmatism therein.

Description:    From the viewpoint of precision and reliability of radioisotopic dating, deposits whose quantitative age can be determined through several methods of geochronometry are of special interest. The mutually conforming finite 14 C and 230 Th/U dates of buried Neopleistocene organic deposits, taken from the Tolokonka section by the North Dvina River (100 km downstream from the city of Kotlas), have been obtained for the first time in Russia. The stratigraphical reference of these results to those obtained via the optically induced luminescence for upper and lower bedding layers has been established. The presented geochronometric data have allowed us to consider the age of oxbow lake organic deposits completely reliable and refer the time of their formation to the Tyrbei warming within the MIS-3. The applicability of the new version of the 230 Th/U method for dating of interglacial and interstadial deposits, for the purpose of solving the Middle and Late Neopleistocene chronostratigraphy issues, is confirmed.

Description:    This paper discusses the results of U-Pb isotopic dating of zircons from hornblendites that cut dunites of the East Khabarny dunite-clinopyroxenite-websterite-gabbro complex in the South Urals. This complex is included into the structure of the large Khabarny mafic-ultramafic allochthon, and the set of rocks and their petrogeochemical peculiarities allow this complex to be compared with the Ural-Alaskan-type complexes. Zircons from hornblendites have been dated on a SHRIMP-II ion microprobe and by the classical thermo-ionization mass spectrometric method by five fractions. The obtained results are comparable between each other within the analysis deviation interval and show that hornblendites were formed in the Early Devonian (408–402 Ma). This age is the upper geochronological limit in estimation of the time when dunites of the East Khabarny complex were formed. The synchronity of intrusive hornblendite manifestation in most of the Urals in the Early Devonian is discussed. The probable Early Devonian stage, in addition to the found Vendian and Ordovician-Silurian ones when dunite-clinopyroxenite-gabbro complexes formed in the Urals, is suggested.

Description:    Electrical conductance of lower crust and mantle rocks samples from the Tarim and Tien Shan junction zone were measured in a laboratory under P-T conditions determined on the basis of thermobarometry data. The geothermic curve for the moment of xenolith delivery corresponding to a thermal flux of 80 mW/m 2 was determined. Its comparison with the present-day geothermic curve corresponding to 60 mW/m 2 demonstrates general cooling of the lithosphere. The Moho surface position also changed from 35–40 km (as the boundary between lherzolites and granulites) to 55–60 km, as a proper geophysical Moho discontinuity. Results of laboratory measurements of electrical conductance of upper mantle and lower crust rocks samples in correlation to geoelectric and thermal models make it possible to define lherzolite, granulite, and eclogite massifs in the depth zone of the Tarim and Tien Shan junction.

Description:    The patterns of renewal of bottom waters in Lake Baikal under the influence of deep convection and intrusion of cold waters have been considered based on the data of temperature surveys of Lake Baikal conducted in 1993–2009. The volumes of the cold bottom layer with the maximums of 200–470 km 3 in individual years and the values of its total cooling (−20–60 × 10 9 MJ) have been determined for South, Middle, and North Baikal. The renewal process is asynchronous and proceeds with different activity in these parts of the lake, which indicates that the mechanisms that cause deep convection in the context of the great latitudinal length and differences in the climate and hydrological processes manifest themselves regionally. The volume of intrusions has been determined. Its average value for the period was higher in South Baikal (20 km 3 ) than in Middle Baikal (9.8 km 3 ) and North Baikal (8.6 km 3 ). The volume of the intrusions in these parts of the lake was 30–70 km 3 in some years. Content Type Journal Article Pages 652-655 DOI 10.1134/S1028334X11050096 Authors M. N.

Description:    This paper presents the results of Sm-Nd isotopic-geochemical and U-Pb geochronological studies of metamorphic (Ilikan Sequence) and associated igneous rocks from the Ilikan lithotectonic zone (terrane) located in the Dzhugdzhur-Stanovoi Superterrane from the Central Asian Foldbelt. The Nd model age, T Nd (DM), of metamorphic rocks from the Ilikan Sequence is 2.6–3.2 Ga pointing to the likelihood that the lower boundary of their protolith formation probably does not exceed 2.6 Ga. The age of detrital zircons from metasedimentary rocks of the Ilikan Sequence is 2700–2900 Ma, which absolutely agrees with Sm-Nd isotopic-geochemical results. The U-Pb zircon age of metagabbro that intruded the rocks of the Ilikan Sequence and underwent high-temperature amphibolite metamophism with subsequent structural transformations is 2635 ± 4 Ma. The obtained results allow us to conclude that the age of the Ilikan Sequence is 2630–2700 Ma. All this gives grounds to state that the Dzhugdzhur-Stanovoi Superterrane in the Central Asian Foldbelt was formed due to amalgamation of non-Siberian terranes as is assumed for the Argun, Bureya, and Mamynskii terranes of the Amur Superterrane from the Central Asian Foldbelt.

Description:    U-Pb dating of zircons (SHRIMP-II) has been performed for the first time for granites, granodiorites, and synplutonic granodiorite and melanodiorite bodies of the Shartash and Shabry massifs in the Middle Urals. The time of the formation of the massifs is 300–306 Ma, which is 25 Ma younger than the previous estimates. The age data obtained are in line with the time of the formation of the adamellite-granite series of the Verkhisetsk Batholite (the master sample of tonalite-granodiorite-granite magmatism in the Middle Urals), the series of which is petrochemically close to the rocks of the massifs.

Description:    Progress in understanding the surface dynamics above the subglacial Lake Vostok is achieved owing to use of the ICESat satellite laser elevation measurements, which enabled us to determine surface fluctuations with precision up to 3 cm. A new idea on punctuated equilibrium of the surface above Lake Vostok is elaborated; this idea is concluded in irregular, sharp vertical displacements of the ice surface by up to 40 cm. Deformation of the surface is accompanied with a common raising or lowering, and with local vertical displacements up to 20 cm in amplitude. It has been proved experimentally that snow transport on the surface above the lake causes only redistribution of snow and forms fractal structures that do not have any effect on surface deformation. The form of the surface is not an inclined plane due to many bends that are particularly related to ice flowing on the lake water area.

Description:    Theoretical ideas based on the results of numerical modeling of mantle convection are presented. The thermochemical model has taken into consideration such factors as two-layer structure of the mantle, formation of light substance in the D” layer (owing to transition of metallic components into the core), and heavy substances in subduction zones (eclogite-alteration of the oceanic crust). Numerical experiments have shown that this system allows phenomena of global mantle overturns, which make possible to model the general pattern of the Earth’s geologic evolution. The suggested theory establishes cause-effect relationships in the sequence of geological events and is conformed to all the empirical data.

Description:    Three strong earthquakes that occurred since the end of 8th century have been identified by archeoseismic data in the southwestern part of the Tere Khol’ Depression. The dates for these events are the 9th, 12th, and first two-thirds of 19th century, and the average recurrence interval is 500 years. The relative seismic passivity of the Tere Khol’ Depression at present may be related to the relatively recent discharge of stress in seismogenerating sources.

Description:    The mass balance of the Antarctic Ice Sheet has been calculated based on instrumental estimates of the grounded ice discharge and snow accumulation data. The boundaries and sectional areas of the main ice catchment basins in West and East Antarctica have been determined, and the data on the grounded ice discharge and snow accumulation in these basins have been systematized. The intensity of accumulation and ablation processes in Antarctica has noticeably increased over the last 50 years. The mass balance of the ice sheet in East Antarctica has been and remains positive, while in West Antarctica it was positive in the middle of the last century and has become negative by now. The mass balance of the entire Antarctic Ice Sheet has been and remains positive, while the mass growth has noticeably decreased over the last 50 years.

Description:    On the basis of landscape-climatic reconstructions for warming periods in the past, likely scenarios of future global warming have been developed for various warming levels that might be reached during the current century. The paleoanalogue of global warming by 0.7–1°C is the Holocene climatic optimum (5.5–6 ka B.P.) and that by 1.7–2°C is the last interglacial optimum (about 125 ka B.P.). The complex analysis concerning response of the principal ecosystem components to the expected warming signifies that there will not be any shifts of vegetation zones during the 21st century; reconstruction will touch only the internal structure of vegetable associations and broadening of interzonal ecotones.

Description:    The Mesozoic-Cenozoic rhythmic continental sedimentary rocks are analyzed for every particular period and epoch from the Triassic to the Pliocene. The maximal distribution areas of rhythmic deposits are within the latitudinal zone of 20°-40°. Investigation of rhythmic Mesozoic-Cenozoic carbonate-containing deposits of Europe and North America enables us to attribute rhythmicity to climate change owing to insolation and eustatic variations of oceanosphere’s level, on the one hand, and to compare duration values of the rhythmic unit and rhythmic sequence with cycles of orbital precession, ecliptic plane inclination, and the eccentricity of the Earth’s orbit, on the other hand.

Description:    We have investigated the relationship between periodic trajectories of barotropic atmospheric model and the modes of the model variability. In particular, we have studied the nature of “25 day” mode of variability (Branstator, 1987; Kushnir 1987). This mode arises as a first complex empirical orthogonal function (or “Hilbert EOF” according to (H. von Storch, Zwiers)) for a given system and is a dominant rotational component of the system dynamics. It was shown that the mode structure coincides with several least unstable periodic orbits of the system. The phase portrait of the system in the plane of the first complex EOF has regular shape with maximum of the probability density function in the vicinity of these weakly unstable periodic orbits.

Description:    The Northern Kamchatka and southern part of the Koryak Highland is considered to be an accretion-collision system in the Late Cretaceous and Cenozoic the development of which was caused by the subsequent accretion of various large terranes to the Asian continental margin. The Paleogene Goven Terrane accreted in the Miocene closes this system. Its boundary with the Olyutor Terrane is hidden under the Cenozoic sediments of the Il’pino-Pakhachino interarc trough. The destructive Khaily (March 8, 1991) and Olyutor (April 20, 2006) earthquakes are characterized by an aftershock area extended in the northeastern direction along the axial part of the Il’pino-Pakhachino trough. The aftershock area was intersected by a profile of the earthquake converted-wave method (ECWM) the interpretation of which reveals a correlation loss of the deep reflecting horizons under this area and three faults dipping to the southeast on seismograms.

Description:    This method pertains to oil and gas geology and to geology of sedimentary basins prospective for oil and gas. It includes identifying catagenesis zones in drilled areas within the sedimentary cover of the basin based on assay results for drill cores and cuttings using the standard methods. Analysis is primarily made in order to determine rock catagenesis based on the optical characteristics of vitrinite. A correlation between catagenesis zones and layer seismic velocities obtained from regional and exploration seismic data is made for a drilled area. Both the layer seismic velocities and the degree of rock catagenesis increase with depth under the influence of increasing rock density. Correlations between layer velocities and the degree of rock catagenesis have been established. The following ratios have been determined for the Scotian shelf, Canada, and the Barents shelf, Russia: a protocatagenesis zone (the cap) corresponds to layer seismic velocities ( V lay ) of 1.5–3.3 km/s, a mesocatagenesis zone (the principal hydrocarbon generation area) corresponds to V lay of 3.3–5.0 km/s, and an apocatagenesis zone (an area with a very low hydrocarbon potential) corresponds to V lay of over 5.0 km/s. An advantage of the new method of identification of catagenesis zones is that it can be used prior to drilling. Its conceptual originality and cost efficiency lie precisely in this.

Description:    The study results of modern geodynamics and tectonophysics of the lithosphere of Baikal Rift System (BRS) are generalized. By the data on radii of dislocations, three areas of maximal strain-strength anisotropy of the medium are distinguished, while analysis of seismic moments of earthquakes has showed that in these parts of the lithosphere mostly dip-slip fault-causing quakes of various energy classes take place; i.e., riftogenesis processes dominate. Within the framework of the theory of nonlinear dissipative dynamical systems, these areas are classified as attractor structures of riftogenesis (ASR). ASRs are located in the central part and in the flanks of the BRS, and they form nonlinearity and instability of modern geodynamical and tectonophysical processes in the lithosphere, which are manifested in seismicity of the Baikal Region and Mongolia.

Description:    The characteristics of the short-period shear wave attenuation field in the lithosphere of the Turanian Plate, West Tien Shan, Pamir, and Hindu Kush have been studied. The method based on analysis of the logarithm of the ratio between maximal amplitudes of Sn and Pn waves ( Sn / Pn parameter) has been applied. More than 400 records of earthquakes, obtained at distances of ∼400–1000 km from the AAK digital station, have been processed. It has been found that relatively weak attenuation is observed in the regions of the West Tien Shan and Pamir. The largest area of strong attenuation is located in the region of the Afghan-Tadjik Depression adjacent to Hindu Kush. A wide band of low Sn / Pn parameter values, stretched northeastwards, has been distinguished. Along with the analogous band of strong attenuation, distinguished before in the regions of Central Tien Shan and Dzungaria, it is the continuation of the largest Chaman Fault, which stretches 850 km along the boundary of the Indian Plate. Source zones of strong earthquakes with M ≥ 7.0 that occurred in the first half of 20th century correspond to relatively weak attenuation. Areas of high attenuation, where strong seismic events have not occurred for the last 110 years, are outlined. Analogously to other seismoactive regions, it is supposed that these areas are related to preparation of strong earthquakes.

Description:    Old and modern data are given and discussed. They allow us to decide where the real position of the south marginal suture of the East European Craton is. According to the geophysical and aerogeophysical studies, Paleozoic deposits of the Karpinskii Ridge are bedded upon deeply sunken continuation of Archean-Proterozoic complexes comprising the Voronezh massif and crystalline rocks belonging to the Astrakhan Dome. The latter have a pre-Riphean age. It is possible that the crust in the southeastern part of ridge in a narrow zone with 〉20 km depth of the basement surface (BS) and, partially, in the Sarpinskii trough has oceanic origin.

Description:    Cartographic neotectonic models have been created for the key areas of the coastal sea zone (CSZ) in the Western Arctic. These areas were identified within platforms of different ages. The neotectonics predetermines the most durable component of the CSZ, i.e., a wireframe with a fault block structure, and is one of the principal factors governing its development. In particular, it manifests itself in the difference between the exodynamics of parts of the CSZ, with their morpholithodynamic boundaries being similar to the structural aspect, their lithology being close, and the exposition to sea waves being the same. In predicting the development of the CSZ in the 21st century, one can say that there is a reason for some concern, but not for panic. The results of the investigations performed will assist in developing a more effective concept of shoreline protection and solving other applied and scientific problems associated with the junction zone between land and sea.

Description:    The unity, interrelationship, and interdependence of the processes proceeding in anthropogenic provinces caused by the activity of mining industries are considered from the viewpoint of the concept of hierarchical passivity of natural components. The processes of degradation of natural complexes under the influence of mining industries and the processes of rehabilitation of the vegetation cover when the anthropogenic pressure decreases are analyzed taking the ZAO Karabashmed’, Chelyabinsk region, and the Severonikel’ Combine, Murmansk region, as examples. The intrinsic potential of rehabilitation of natural systems (air, water, and soil) is assessed, and the most passive components are identified. A strategy of reclamation of disturbed territories is enunciated based on the information obtained taking the natural self-recovering ability of ecosystems in different climate zones into account.

Description:    Analysis of major- and trace-element compositions of water in hypersaline soda closed basin lakes of Northwestern Mongolia and Chuya basin (Gorny Altai) shows high enrichment in 238 U (up to 1 mg/l). Proceeding from new data, uranium accumulation in water has been attributed to (i) location of the lakes and their watersheds in potential provinces of U-bearing rocks and (ii) uranium complexing with carbonate in presence of carbonate (bicarbonate) anions. Among the explored hypersaline soda lakes of the area, the greatest uranium resources are stored in Lake Hyargas Nuur (about 6000 ton).

Description:    Micropaleontological and isotope-geochronological investigations of calcareous sedimentary rocks and volcanites dredged out from the central portion of the submarine Vitoria-Trindade Ridge during the 24th cruise of R/V Akademik Vavilov have been conducted. It has been established based on micropaleontological analysis, which included determination of the species composition of foraminifera and nannoplankton, that the sequence of sedimentary rocks having a pelagic nature formed on the slopes of the volcanic seamounts in the central portion of the Vitoria-Trindade Ridge from the Early to Mid-Miocene to the Holocene; a good correlation between the degree of lithification of these rocks and their age is observed. It has also been established that the carbonate platforms on the abraded tops of the Davis Seamount and the Dogaressa Bank, which are located in the east-central portion of the Vitoria-Trindade Ridge, started forming in the Early Miocene (19–24 Ma). It has been determined using local U-Pb dating of zircon grains with a SHRIMP-II high resolution secondary ion mass spectrometer that the volcanites forming the upper portion of the volcanic rock sequence of the Jaseur Seamount (29.8 ± 6.6 Ma) located in the west-central portion of the Vitoria-Trindade Ridge date to the Oligocene. The investigations conducted have confirmed the opinion that the Vitoria-Trindade Ridge formed in general because of the activity of the hot spot located under the volcanic Trindade and Martin Vaz Islands. However, separate extended lenticular segments of this ridge existed for a long time as single structures, within which the age of the seamounts was not linearly dependent on the distance from the location of the hot spot. Lenses of hot mantle matter that form at the sublithospheric level as a result of impulses of plume activity and move along with the lithospheric plate play a defining role in the development of individual segments forming the Vitoria-Trindade Ridge.

Description:    Magmatic rocks from the copper-porphyritic Lazurnoe deposit (Central Primor’e) have been studied. It has been found that rocks from the Lazurnyi massif are referred to gabbro-monzodiorites, monzodiorites, and monzo-granodiorites formed during two magmatic phases of different ages. The earlier phase is represented by gabbro-monzodiorites and diorites of the North Stock, and the later one, by gabbro-monzodiorites and monzo-grano-diorites of the South Stock. On the basis of isotopic dating by the U-Pb (SHRIMP) method for zircon and by the K-Ar method for hornblendes and biotites, the age of magmatic rocks is determined at 110 ± 4 for the earlier phase and at 103.5 ± 1.5 for the later one. Examination of the isotopic composition for Nd, Sr, Pb, Hf, δ 18 O, and REE spectra has shown that melts of the first phase are contaminated with crustal rocks and they are typical for a high degree of secondary alterations. Potassiumfeldspar, biotite, propylitic alterations, and sulfidization are manifested in these rocks. The rocks of the later stage of magmatism are characteristic for a primitive composition of isotopes and the absence of secondary alterations. They carry the features of adakite specifics that allows us to consider them derivatives of mantle generation under high fluid pressure. The intrusion of fluid-saturated melts of the second phase into the magmatic source of the first phase caused both an alteration pattern of rocks and copper-porphyritic mineralization. Isotopes of sulfur and oxygen allow us to consider the ore component to be of magmatic origin. Content Type Journal Article Pages 569-577 DOI 10.1134/S1028334X11050072 Authors V. G.

Description:    The U-Pb(Pb-Pb) age was determined for limestone from member III of the Sorna Formation out- cropped on the Azyr-Tal Range, Kuznetsk Alatau. The weighted average value from three calculated values is 523 ± 5 Ma (MSWD = 0.02, 2σ). This age coincides with the Early Cambrian age interval determined with Sr isotopic chemostratigraphy ( 87 Sr/ 86 Sr ratio is 0.70850–0.70852). The low value of μ 2 = 238 U/ 204 Pb for limestone is due to the evolution of diagenetic fluid containing lead from the mantle reservoir into the Sorna sediments.

Description:    Calculation of the downward continuation for the anomalous magnetic field at the Knipovich Ridge showed more complicate segmentation of the spreading oceanic basement than was earlier considered. The structural pattern of the field is evidence that the area consists of no less than four segments separated by transform fracture zones with the azimuth of oceanic crust accretion about 310° and the normal position relative to the rift segments with the azimuth of 40°. The modern location of the axis of the Knipovich Ridge straightens the complicate divergent boundary between the plates in the strike-slip conditions between the spreading centers of the Mohns and Gakkel ridges. The axis is a detachment zone intersecting the oceanic basement having formed from the Late Oligocene. A new magnetoactive layer composed of magmatic products has not yet been formed in this structure. Content Type Journal Article Pages 343-348 DOI 10.1134/S1028334X11030275 Authors S. Yu.

Description:    Experiment on electromagnetic sounding of the Kola Peninsula using unique mobile measuring complex of the low-frequency sounding was conducted, allowing to investigate a geoelectric section with a depth of several kilometers on distances up to 100 km from the stationary transmitting aerial. Excess on the order of amplitudes of the vertical component above the horizontal at all frequencies of sounding was registered in a number of points of measurements. This feature managed to be explained quantitatively by circulation of current on regional faults with the closure of current through the sea—before unknown galvanic coastal effect. Interpretation of the results of modeling and neural network solving of inverse problem essentially specifies the fault tectonics of the central part of the Kola Peninsula. Anomaly remote from the observation profile was found out—local pinch of a crustal conductive layer consisting of graphitized rocks and associated with the zone of overthrust.

Description:    The discovery of the Pliocene red panda ( Parailurus ) in the West Transbaikal area, as well as Asian raccoons in North Eurasia and North America, indicates that forested areas with bamboo bushes were wide-spread in the Holarctic during the Neogene. During the Late Pliocene, due to a gradual cooling of the climate, altiplanation, and other factors, their habitat started disintegrating, and red pandas began dying out, surviving only in China.

Description:    This work is devoted to study of interannual variability of characteristics of Pacific summer waters (PSWs) supplied into the AO in summer. The distribution area, volume, and heat content of PSWs have been calculated for the first time for the entire Arctic Basin in the periods of 1950–1989 and 2008–2009 demonstrating the presence of substantial interannual variability. From 1953 until 1983 a negative trend and since 1984 a positive trend have been observed; the latter lasted until 2009, when the heat content, volume, and distribution area of PSWs reached their maximal values for the entire period considered. It has been shown that PSW quantity in the Arctic Basin, identified by temperature, rather depends on the intensity of heat flux through the Bering Strait, and the calculated value for PSW life in the Arctic Basin is seven years.

Description:    The Northern Kamchatka and southern part of the Koryak Highland is considered to be an accretion-collision system in the Late Cretaceous and Cenozoic the development of which was caused by the subsequent accretion of various large terranes to the Asian continental margin. The Paleogene Goven Terrane accreted in the Miocene closes this system. Its boundary with the Olyutor Terrane is hidden under the Cenozoic sediments of the Il’pino-Pakhachino interarc trough. The destructive Khaily (March 8, 1991) and Olyutor (April 20, 2006) earthquakes are characterized by an aftershock area extended in the northeastern direction along the axial part of the Il’pino-Pakhachino trough. The aftershock area was intersected by a profile of the earthquake converted-wave method (ECWM) the interpretation of which reveals a correlation loss of the deep reflecting horizons under this area and three faults dipping to the southeast on seismograms.

Description:    This paper presents new data on numerous small metallic particles of iron, copper, Fe-Ni, Fe-Ni-Co, and Fe-Cr alloys, magnetite, and aluminosilicate balls of cosmic origin found in the black clay boundary layer between the Cretaceous and Paleogene in the Stevns Klint Section (Denmark). The findings imply that a fall of an asteroid to Earth 65 Ma ago was accompanied with falling of finely dispersed metallic particles of extraterrestrial nature related to the asteroid fragments or to micrometeorites following the asteroid or to the intense supply of cosmic dust. The huge amount of finely dispersed matter that fell to Earth at that time should be considered in further reconstructions of events at the boundary of the Cretaceous and Paleogene.

Description:    This paper describes seasonal peculiarities of modern climate warming in the European region. It is shown that warming scenarios considerably differ in cold and warm periods of the year. The warming is accompanied with growth and considerable change in the phase of the yearly cycle in solarity data. A strong half-year cycle is recognized in seasonal variation of long-term trends over the last few years. Peculiarities of climate change in Europe and the increased influence of the tropics are discussed in view of the results obtained.

Description:    The contents of 60 macro- and microelements were determined by inductively coupled plasma mass spectrometry in the samples of ferromanganese crusts collected on submarine slopes of the Kuril Islands. Along with a pronounced variability in the chemical composition of the crusts, the contents of several microelements vary according to the values of the europium anomaly. A positive value points to local volcanogenic hydrothermal activity, which provides for the accumulation of manganese and iron at the expense of the accumulation of some nonferrous and rare metals.

Description:    We consider the problem of penetrative convection in the upper ocean under the conditions of sharp surface cooling and a constant momentum flux connected with the existing system of random waves. The Langevin equation with a random right part is used to describe a convective ensemble of thermals. The kinetic Fokker-Planck equation is built for the angular probability density of an ensemble of convective elements. The stationary solution of this equation allows one to find an analogue of the Boltzman distribution for convective currents over speed and height. The Maxwell speed distribution is implemented in this case for convective thermals at a fixed depth. The results allow interpretation of certain data on turbulence in the convective near-surface ocean layer.
