The Late Pleistocene–Holocene climate history in the western Todzha basin (Eastern Tuva)     

S.G. Arzhannikov  S.V. Alekseev  A.V. Glyzin  N.V. Kulagina  N.V. Ignatova  L.A. Orlova 《Russian Geology and Geophysics》2010,51(2):163-175

The Late Quaternary history of climate and deposition environments in the western Todzha basin has been reconstructed from the respective lacustrine and fluvial deposits. Data from sedimentary sections have provided clues to the causes and timing of sudden deposition changes, including those associated with Holocene tectonic activity in the Taskyl fault. Especially informative are permafrost, diatom, spore-pollen, and tree-ring data from a section at the Merzly Yar locality where frozen ground has preserved the pristine rhythmic pattern of sediments. The Merzly Yar section stores a record of dramatic consequences of large earthquakes generated by the fault which produced a large damlake. The revealed pattern of discontinuous limnic deposition, with prominent tree markers and syngenetic ice wedges, places exact constraints on the stratigraphy of the section and allows its correlation with Holocene climate events within the intervals of fossil soils and vegetation.  相似文献   

Mineralogical attributes and causes of high-pressure crystallization of Li-F granites     

V. I. Alekseev 《Geology of Ore Deposits》2010,52(7):534-542

Mineralogical indications of high-pressure crystallization of Li-F granites from Russia, Kazakhstan, and Mongolia are discussed. Syngenetic deformation of minerals (protoclasis) in these rocks has been revealed and described for the first time. A possible cause of the effect of high pressure on the solid phase during its crystallization from melt is considered. A progressive increase in pressure and manifestation of fluid overpressure in the course of crystallization is established. It is suggested that the idea of overpressure stated by V.S. Sobolev and N.L. Dobretsov may be applied to rare-metal magmatism.  相似文献

Protolith age of eclogites from the southern part of Pezhostrov Island,Belomorian belt: Protolith of metabasites as indicator of eclogitization time     

S. G. Skublov  A. V. Berezin  A. E. Melnik  B. Yu. Astafiev  O. A. Voinova  V. I. Alekseev 《Petrology》2016,24(6):594-607

Several types of metabasites of different age were identified in the southern part of Pezhostrov Island: eclogites with a magmatic protolith age of about 2200 Ma and 2500 Ma old metagabbroanorthosites that retained no eclogitic assemblage. It is shown that the Paleoproterozoic eclogites dominate volumetrically over Archean eclogites in the Belomorian eclogitic province. Eclogites with the youngest Jatulian protolith age (no older than 2200 Ma) occur with the same frequency as those with the Archean protolith age. A new find of eclogites with a Paleoproterozoic age of magmatic protolith and generalization of accumulated geochronological data confirm the recognition of an extended zone of high-pressure metamorphism with an age around 1900 Ma in the Belomorian mobile belt.  相似文献   

The influence of the North Atlantic on climate variations in the Barents Sea and their predictability     

G. V. Alekseev  N. I. Glok  A. V. Smirnov  A. E. Vyazilova 《Russian Meteorology and Hydrology》2016,41(8):544-558

The effects of Atlantic water inflow on the climate variability in the Barents Sea are studied. Initial data are the series of water temperature at the Kola meridian cross-section, monthly values of ice extent, air temperature at the stations, sea level pressure from the reanalysis data, and sea surface temperature. The methods of multivariate correlation, spectral, and factor analysis and EOF decomposition are used. It was found that variations in the Atlantic water inflow define the main part of interannual variability of sea ice extent, water temperature, and air temperature in the Barents Sea in the cold season. The influence of regional atmospheric circulation on the interannual variability of these parameters is small. The effects that water temperature anomalies in the area of Newfoundland and in the equatorial part of the North Atlantic have on climate parameters in the Barents Sea are discovered. The response of these parameters lags behind the respective anomalies by 9-58 months. The high correlation between them makes it possible to develop the method of statistical forecasting of sea ice extent and water temperature in the Barents Sea with the lead time up to 4 years.  相似文献   

Simulation of the Evolution of Wave Fields Induced by a Moving Cyclone over the Northwest Shelf of the Black Sea     

D. V. Alekseev  V. A. Ivanov  E. V. Ivancha  V. V. Fomin  L. V. Cherkesov 《Physical Oceanography》2005,15(1):37-49

The wave fields generated by cyclonic atmospheric disturbances in the region of the northwest shelf of the Black Sea are studied by using a σ-coordinate model. The problem is solved in the hydrostatic approximation with regard for nonlinearity and turbulent viscosity. To improve the space resolution of the model, we realize the procedure of embedded grids. It is shown that the action of a cyclone results in the formation of domains of pronounced surges whose shapes and location reflect the changes in the wind situation. The vertical structure of wave currents first depends only on the location of the atmospheric disturbance over the water area but, in the course time, begins to reflect specific features of the bottom topography.__________Translated from Morskoi Gidrofizicheskii Zhurnal, No. 1, pp. 42–54, January–February, 2005.  相似文献
