(2006)Within the framework of a Joint Russian–German project, sediments of Lake El’gygytgyn were studied to determine paleoclimatic changes in the Pleistocene and Holocene. A 13-m-thick upper section of the bottom sediments was ...
-
(2006)In this paper, we present the results of experimental measurement of the mechanical rigidity of the Oka sector of the deep Nelidovo–Ryazan tectonic structure (NRTS) and auxiliary faults of order II. The kn and ks values ...
-
(2006)Sakhalin is the only region in the Russian Far East where recent active gas–water–lithoclastic (hereafter, mud) volcanism is widely developed and has long been known. Among four regions of mud volcanism developed on the ...
-
(2006)Based on the application of online satellite images of cloud cover, we studied the influence of different stages of the development of typhoons on seismic processes in the Asian–Pacific region, determined the earthquake ...
-
(2006)The method of revealing probable areas of future strong earthquakes (“seismic gaps”) was first proposed with the Kuril–Kamchatka island arc (KKA). The method is based on the following principle: sources of the strongest ...
-
(2006)The authors of the present paper worked out and produced a device that allows us to model the samples of methane hydrate-containing rocks and to measure their thermal conductivity. Thermophysical parameters can be assigned ...
-
(2006)Numerous deposits and occurrences of high-quality chromites in the Urals are related to the Alpine-type dunite–harzburgite ultramafic rocks. The chromite ore mineralization is characterized by extremely complicate localization ...
-
(2006)We have attempted to analyze the relationship between tide and seismicity with due regard for the development of creep in the Earth’s crust, which depends on the strain duration and, hence, on the harmonic period. We studied ...
-
(2006)The authors of developed the geophysical interpretation of the generation and motion of macroscale ionization inhomogeneities in the ionosphere (MIIIs) in the altitude region of maximal electron concentration. The objects ...
-
(2006)Recent geological–geophysical studies of gold ore districts in the Russian Far East specified the essential role of Precambrian massifs, salients, blocks, deep faults, and protomagmatic chambers in distribution of noble ...
-
(2006)The Barents Sea continental margin (hereafter, Barents margin) differs from other passive margins by the most extensive shelf, the giant thickness of sedimentary rocks in basins and troughs, and its unique tectonic position. ...
-
(2006)Comparative petrological and geochemical characteristics are presented for the rocks from two areas in northern Karelia in the northeastern and southwestern parts of the Belomorian Mobile Belt. Both of the areas were ...
-
(2006)An 1800-km South to North transect (N 53°43′ to 69°43′) through Western Siberia was established to study the interaction of nitrogen and carbon cycles. The transect comprised all major vegetation zones from steppe, through ...
-
(2006)Strong earthquakes in the southern part of Gornyi Altai on September 27 and October 1, 2003 clearly demonstrated the correctness of the previous concepts of the general high seismic potential of the region. On the other ...
-
POSSIBLE GEOCHEMICAL CONDITIONS OF LOCAL REDUCING ENVIRONMENTS IN THE EARTH'S CRUST AND UPPER MANTLE (2006)The proportion of ç2é + ç2 in the gas phase equilibrated with an assemblage of solid phases is buffered by the interaction with Fe and is related to the ratios of FeO (Fe) and Fe3O4 (FeO) activities in the solid phases at ...
-
(2006)The heterogeneous different-aged terranes constituting the Pacific margin of Asia include numerous fragments of ancient accretionary prisms. One of these is the Jurassic prism, exposed over more than 5000 km from the left ...
-
(2006)he present paper is based on the geotectonic interpretation of marine geological–geographical data with consideration of publications devoted to paleomagnetic investigations and isotope datings of rocks from the adjacent ...
-
(2006)Physiographic zones of the Earth are “major units of the geographic (landscape) sphere, which give way to each other in a regular and definite order depending mainly on the ratio of heat and moisture”. The rise in the ...
-
(2006)Oil and especially the related associated bitumen, in particular, are characterized by high metal contents with a predominance of V, Ni, and Zn that make up a specific “oil” assemblage. Based on the prevalence of one of ...
-
(2006)We studied micropolycrystalline diamonds from modern and Neogene–Quaternary alluvial placers found in the main diamondiferous areas of Brazil (Minas Gerais, Bahia, and Mato Grosso). The polycrystalline inclusions were found ...
