GEOMORPHOLOGICAL CORRELATION OF LATE PLEISTOCENE GLACIAL COMPLEXES OF WESTERN AND EASTERN BERINGIA (2001)Many fundamental problems exist in comparing the chronology and correlation of Late Pleistocene glaciations between Western and Eastern Beringia. However, geomorphological analysis, complemented by palynological studies ...
-
(2001)Geomorphological investigations in the catchment area of the Baydragiyn river along the southern slope of the Khangay and in the Valley of the Gobi Lakes in western Mongolia provide evidence for Late Quaternary glaciations ...
-
(1992)The study of samples from collections from one of the geological provinces of the Ukrainian shield that formed under different pressures and temperatures revealed a clear-cut connection between distribution features of ...
-
(2004)In this paper, we present the results of integrated observations of optical, infrasonic, and seismic perturbations caused by the flight of a bolide over the middle course of the Vitim River at a distance of approximately ...
-
(2001)New 2-D seismic reflection data from the South Caspian Sea, offshore Azerbaijan, document for the first time in the deep water (up to 650m) of this area, the presence of gas hydrates. Geophysical evidence for gas hydrates ...
-
(1999)This paper presents the results of geophysical measurements that were performed above the Belyankin and Smirnov submarine volcanoes during cruises of the R/V Vulkanolog. The morphology of the volcanoes, the distribution ...
-
(1999)It has been inferred previously that the lower mantle is much less degassed than the upper mantle, by about two orders of magnitude, based on estimates of the amount of 40Ar expected to have been generated during earth ...
-
(2003)In this article we present a geostatistical approach to the transmission tomographic inverse problem, which is based on consideration of the inverse problem variables (velocity and traveltime errors) as regionalized variables ...
-
(2003)Practical application of geostatistical inversion to coupled problems is hampered by a number of difficulties. In this paper, we address two of them: first, the computational cost of sensitivity (Jacobian) matrices and, ...
-
(2004)An issue that often arises in such GIS applications as digital elevation modeling (DEM) is how to create a continuous surface using a limited number of point observations. In hydrological applications, such as estimating ...
-
(2003)Automatic methods used in geosciences to interpolate between orientation data have often limited applicability and strength, in particular where large ranges of orientations occur. In this paper, we show that geostatistical ...
-
(2004)This paper introduces geostatistical approaches (i.e., kriging estimation and simulation) for a group of non-Gaussian random fields that are power algebraic transformations of Gaussian and lognormal random fields. These ...
-
(1995)Heating ortho-undecyltoluene with an acidic clay catalyst and hexamethylbenzene as a methylating agent resulted in the formation of hydrocarbon mixtures containing undecyltoluenes and dimethylundecylbenzenes. At short ...
-
(2004)There are more and more prerequisites for the fundamental theoretical synthesis of new concepts concerning the anthropogenic transformation of our planet. One can recognize three most important groups of factors among these ...
-
(2004)The geological position and structure of the large uranium-bearing Novoukrainsk ore field, confined to the Novoukrainsk granitic massif in the central part of the Ukrainian Shield, is reviewed. It is shown that the ...
-
(1999)The bulk of the Kamchatkan hydrothermal manifestations and all high-temperature hydrothermal systems are located in three volcanic belts: the East Kamchatka, South Kamchatka, and Sredinnyi Ridge volcanic zones. The fact ...
-
(1985)Geophysical data indicate that beneath Late Cenozoic continental rift zones there are asthenospheric upwellings with their upper surfaces reaching the Moho at depths of 30–40 km. Under neighboring stable regions the ...
-
(2003)A new investigation of the thermal conductivity of the drill cores from the research drill hole Nördlingen 1973 in the Ries impact structure was conducted. The 1206 m deep drill hole penetrated 331 m of post-impact lake ...
-
(2003)There are two well-founded hypotheses of the Ninety-East and Chagos-Laccadive Ridges genesis: the hypothesis of the extrusive source disposed at a junction of the spreading axis with transform fault and the hot spot ...
-
(1987)A comparison of the probability density distribution of the heat flux with the distribution of dimensions of blocks shows that the two are qualitatively identical. Two characteristic peaks are identified on these distributions: ...
