-
(2001)The L and M X-ray emission spectra of tantalum carbide, boride. nitride, silicide, aluminide and tantalum-hafnium carbide were found to be complex in nature. These spectra were analysed by a curvefit programme and were ...
-
(2004)Brachiopods are among the fossils groups frequently occurring in sections of the southwestern Crimea. The analysis ofjoint stratigraphic distribution ofammonite and brachiopod assemblages that has been stimulated by revision ...
-
(2004)The marginal configurations and ages of the Valdaian (Weichselian) glacial maxima in northern Russia have hitherto not been well established, thus, numerous versions of the Last Glacial Maximum (LGM) positions of the ...
-
(2002)The effect of pressure on the valence and structural state of iron atoms was experimentally studied at pressures up to 5 kbar in natural basaltic melts under closed system conditions. Basaltic glasses were produced by ...
-
(2001)The microstructure of hematite-ilmenite exsolution intergrowth of a natural titanohematite crystal from a granulite has been investigated in a transmission electron microscope equipped with an energy filter. Special emphasis ...
-
(2004)We have studied the polarized optical absorption and EPR spectra of Co-doped beryls grown by hydrothermal, flux, and gas-transport methods, and chrysoberyl grown by the Czochralski method. In beryls three groups of bands, ...

VALER'YANOVSKII VOLCANOPLUTONIC BELT: PROBLEMS OF RELATIONSHIPS BETWEEN MAGMATISM AND ORE FORMATION (2003)Skarn magnetite deposits of the Valer'yanovskii volcanoplutonic belt (Tyumen-Kustanai depression and regions east of the middle and southern Urals) were studied with applications to the problem of the relationship of ...
-
(2003)O1 and M2 observations from well-calibrated spring gravimeters and superconducting gravimeters from the Global Geodynamics Project (GGP) are used to test models of the Earth's body tide and 10 ocean tide models. It is shown ...
-
(2002)Digital drainage direction maps are a prerequisite for analyzing the flow of water on the land surface of the Earth. For continental or global studies, the most appropriate and most frequently used resolution for such data ...
-
(2001)Surface depression storage influences runoff, but is difficult to measure, because water infiltrates into the soil. Therefore, it is usually estimated using a numerical method. This consists of taking height measurements ...
-
(2001)A radiometric color model relating the color of optically complex (non-Case I) waters to the organic and inorganic color-producing agents (CPA) responsible for that color has been previously applied to the waters of Lake ...
-
(2002)A genetic algorithm is used here to guess-estimate a close-to-true set of trial values as input to a three-staged quasi-linear inverse modeling scheme for the determination of aquifer parameters. To validate the parameter ...
-
(2002)Spherical harmonic error analysis fully relies on the validity of the a priori observational and stochastic models. In this paper we validate error analysis results of the gradiometer mission GOCE by a full-fledged spherical ...
-
(2001)Forsterite single crystals doped with vanadium were grown from melt using the Czochralski technique in various oxidation-reduction conditions: nitrogen, nitrogen with oxygen, argon, and argon with hydrogen atmospheres. The ...
-
(1996)We assess the potential of using foraminiferal calcite as a paleoceanographic indicator of seawater V concentrations. Laboratory culture experiments show that living benthic and planktonic foraminifera incorporate V into ...
-
(2003)The compatibility of vanadium (V) during mantle melting is a function of oxygen fugacity (fO2): at high fO2’s, V becomes more incompatible. The prospects and limitations of using the V content of peridotites as a proxy for ...
-
(2002)New measurements of partition of vanadium (V) between spinel, garnet and a pigeonite-like high pressure (P) pyroxene and magnesian liquids on the mantle solidus as a function of oxygen fugacity (fO2) are presented. The ...
-
(2004)We measured the adsorption of V(V) onto goethite (α-FeOOH) under oxic (PO2 = 0.2 bar) atmospheric conditions. EXAFS spectra show that V(V) adsorbs by forming inner-sphere complexes as VO2(OH)2 and VO3(OH). We predicted the ...
-
(2001)Seismograms recorded by the Global Seismic Network can be processed to obtain receiver strips for each earthquake. The receiver strips for all earthquakes can be analysed simultaneously in the time domain by using the ...
-
(1996)Dehydration-melting experiments from 10 to 20 kbar were performed on a metavolcanoclastic rock containing (in vol. %) biotite (16), amphibole (15) and epidote (13) in addition to plagioclase and quartz. At 10 and 12.5 kbar ...
